Vollmer introduces new grinding technology

November 29th, 2021 9:13 am | by Admin

At the recent EMO exhibition, VOLLMER delivered the exhibition premiere of its new VGrind 360S grinding machine for the complete machining of carbide tools. Acknowledged as the new standard for the complete machining of rotationally symmetric solid carbide tools, the exciting new VGrind 360S is the perfect solution for manufacturing cutting tools for aerospace, medical, automotive and general subcontract manufacturing sectors.

This new 5-axis CNC grinding machine can be used productively to machine carbide tools with a diameter up to 25.4 mm and depending on the machine kinematics and the equipping of the grinding wheel packages, it can even be used for tools up to 150 mm diameter. The VGrind 360S incorporates wear-free linear induction motors on the X, Y and Z-axes to lower maintenance costs for the machine whilst demonstrating higher surface quality for the tool and improved precision.

The tried-and-tested vertical double-spindle concept from VOLLMER now features an oriented spindle-stop for the first time. Also known as spindle indexing, this always stops the spindle at a specific position and the result is a reduction of axial run-out errors and concentricity issues whilst offsetting wear in the HSK holding system. Another new feature is a heat plate exchanger to efficiently cool motors and spindles, which in turn leads to increased thermal stability. Furthermore, this effective cooling concept that has now been optimised and extended demonstrates absolute perfection when processing tools to the tightest of tolerances.

Simple and intuitive operation is at the core of the VGrind 360S and for customers to fully exploit its potential, VOLLMER has created an ergonomic platform whereby users can operate the control panel comfortably whilst having full visibility of the work envelope. Operation via the keyboard or touchscreen allows for precise machining of the tool and the multi-function handwheel ensures even more flexibility as it can be freely positioned on the enclosure. This design allows the setting of a required axis without using the control panel.

The VGrind 360S incorporates VOLLMER’s trusted operating concept and can be operated unmanned around the clock thanks to automation features such as a pallet magazine, free-arm robot or chain magazine. The options for automation include the HP 160 pallet magazine for up to 900 tools with a double gripper to guarantee fast changeovers, the HPR 250 free-arm robot for the automatic machining of tools with various shaft diameters and the HC 4 chain magazine that has space for 39 HSK-63A tools or up to 158 shank-type tools. This automation also extends to the 8-tool grinding wheel changer that ensures you always supply the right grinding wheel for the job at hand with no manual intervention. As an option, coolant nozzles can be automatically exchanged with the wheel sets on both spindles.

VOLLMER has everything covered for maximum productivity and performance. The optional features include the flexible loading automation options for carbide tools, grinding spindles available with direct or belt drive, automatic gripper compensation as an in-process solution, wheel compensation probes, automated changing of intermediate sleeves with bayonet, an automatic stacking unit that enables the abrasive grinding wheel to be opened during the grinding process. Other available features include the simultaneous grinding wheel package and tool change in combination with the HP 160 pallet magazine or the HC 4 to reduce non-productive times during loading and a stable, fully adjustable steady rest with automatic stroke to prevent deflection and ensure optimal grinding results.

Automation is raising grinding technology productivity

November 26th, 2021 1:21 pm | by Admin

GrindingHub to showcase efficient fine machining processes
Fine machining requires a great deal of intuition. That is why many companies still take care of grinding and polishing manually. However, this can quickly become a source of high costs and inconsistencies, especially in series production. Automation solutions deliver reproducible quality at all times. With its combination of grinding technology, automation systems and software, GrindingHub 2022 will be the perfect place for companies to obtain all the information they require on this challenging field.

Unmanned production 24/7
For many manufacturing companies, this is one of the key factors for success in this highly competitive field. This has been the case for turning, milling and drilling technologies for some time, but increasingly now also for fine machining. Exhibitors at GrindingHub will be providing a first glimpse of their solutions for achieving significant increases in productivity and reproducibility levels.

Robot-assisted grinding
Top quality surfaces are essential in metal and woodworking as well as in the automotive and aerospace industries. Fine machining in particular is still performed by hand in many cases, as human sensitivity is difficult to imitate. However, manual polishing, grinding and brushing is time-consuming and exhausting work. Automated processes offer an attractive alternative, allowing flawless surfaces to be created faster and at lower cost. At the same time, they relieve people from monotonous and dusty work.

The new tools for automated machining from Schunk GmbH & Co. KG based in Lauffen am Neckar, have innovative features which compensate for force and positional inaccuracies, allowing near-perfect results to be achieved. For example, a pneumatic random orbit sander with axial compensation is the company’s “specialist” when it comes to grinding and polishing. Its adjustable compliance yields constant contact force and uniform surfaces. Users seeking a highly robust and flexible tool for polishing and brushing workpieces will find a suitable solution in the pneumatic polishing spindle. It shortens machining and start-up times by a significant margin. The compensation force and the axial compliance of the tool are individually adjustable, which yields high-quality and reproducible results regardless of the installation position. Different workpiece geometries can be flexibly machined with just one tool, an economic advantage that almost halves investment costs. Schunk offers its application know-how to support customers in making the change from manual to automatic.

“We don’t just sell the appropriate machining tools for the robots, we keep the entire application in mind. On request, we test and validate every application on the customer’s workpiece in our CoLab robot application centre,” assures Daniel Mayer, director Product Sales Robotic Material Removal. “At the end, you receive a test report and video, giving you certainty that the application works.”

 “The closed loop ensures superior manufacturing quality as well as minute profile tolerances, together with maximum user-friendliness. Even with extremely challenging workpieces, such as grinding wheel bases, turbine blades or grooving inserts, it has proven to be a robust solution on the shopfloor,” says Marie-Sophie Maier-Wember, managing director of Haas Schleifmaschinen in Trossingen. Software is becoming a driver of precision working because mechanical forces are constantly in play during grinding, especially towards the edges of the grinding tools. These forces affect the interaction between the workpiece, grinding tool, clamping device and grinding machine. They result in ever-increasing levels of inaccuracy, which has an adverse effect on workpiece quality, especially if the system does not allow for a continuous exchange of data between the workpiece and the grinding machine. A self-controlling process based on an integrated measuring solution effectively prevents this loss of precision. Any systematic and machine-specific deviations are continuously identified by measurement technology during operation and forwarded to the Haas grinding machine software. This incorporates a large number of compensatory functions which complement each other. Any deviations in shape can thus be compensated down to µ-level precision.

“Without compensation, the tolerance would be several µ. In the closed loop, we create tolerances down to just a few µ without intervention by the machine operator,” explains the managing director. In addition to acting as a driver of precision, Haas grinding machine software solutions have a direct impact on customer shopfloor operations. The Haas grinding machine series can be connected to the ERP system, allowing automatic tool changing and the further processing of production data.

Future-proof: networked and automation
Automation solutions have long been an integral part of the product portfolio of Hamburg-based engineering company Blohm Jung GmbH, part of the United Grinding Group. A typical example of this is the tool changer for the current series of grinding machines. Designed for maximum cost efficiency, the solution offers users numerous benefits from reduced setup times to virtually unmanned processing, even of complex workpieces.

“Automation is only one of the key factors involved in increasing productivity,” explains Stefan Springer, head of Product Management at Blohm Jung. “Machine connectivity is also gaining in importance, as the future of industrial production will be networked.” Machines are communicating with each other, exchanging data, controlling and regulating each other. This makes processes run more efficiently and increases productivity. Blohm Jung’s “digital production monitor”, for example, offers customers the ideal tool for digitally monitoring and optimizing production capacity utilization from anywhere, 24/7. Running and non-running times, piece counts or malfunction times are displayed in real time. This allows any production backlogs to be detected at an early stage. IT security is given top priority here. Online access to the machine is only granted if the customer submits a service request. Data is therefore only exchanged with the customer’s consent and then only the data which is necessary for providing the desired service. Blohm Jung uses a TÜViT-certified connection to ensure that the data is protected from unauthorised access at all times.

The advantages of the latest products and solutions can be clearly explained and discussed in direct meetings with the experts. Do we have the right equipment for the next project? Which is the best fine machining technique for a specific component and how exactly does the software help me with the manufacturing processes? Interested visitors can find out how to future-proof their processes at the individual companies’ stands at GrindingHub 2022 in Stuttgart.

GrindingHub 2022 in Stuttgart
The first ever GrindingHub will be held in Stuttgart from 17 to 20 May 2022 and is the new leading trade fair and centre for grinding technology. It is scheduled to be run every two years by the VDW (German Machine Tool Builders’ Association), Frankfurt am Main, in cooperation with Messe Stuttgart and with Swissmem (Swiss association of mechanical and electrical engineering industries) as its institutional patron. Grinding is one of the top 4 manufacturing processes within the machine tool industry in Germany. In 2020, the sector produced machines to the value of 870 million euros. Almost 80 percent were exported, with about half going to Europe. The largest sales markets are China, the USA and France. Germany, Japan and Switzerland head the list of top global producers. The grinding technology sector produced 4.9 billion euros worth of machines in 2019.

Latest trends in grinding and tool grinding technology

November 1st, 2021 11:17 am | by Admin

e-mobility, digitalisation and automation: these are just some of the key trends in the grinding technology sector at present.

Research experts and the companies exhibiting at the new GrindingHub trade show will be providing insights into the latest technologies and processes in this rapidly developing industry.

e-mobility is bringing about a change in the entire powertrain in cars. Gear parts must be ever lighter and increasingly precise and robust. Liebherr-Verzahntechnik GmbH has been taking a very close look at the requirements of e-mobility. Flank line modification methods are used to minimise noise and optimise load capacities. Here, generating grinding with dressing-free CBN grinding worms can represent an economical alternative to corundum worms. The process is reliable, ensures long tool life and significantly reduces the amount of time and effort required for measuring and testing.

The grinding process and clamping equipment for the production of finely worked e-bike transmission parts must be fast and precise. Using special clamping solutions, even small and collision-critical components can be machined without any problems. The exclusive Liebherr machine concept with single-table helps achieve optimum concentricity and high reproducibility in the production of parts with quality requirements in the micrometer range. The choice of process ultimately depends on the specific requirements. Liebherr can test all process parameters using its own machines. “Often there is no right or wrong,” explains Dr. Andreas Mehr, an expert in gear grinding. “As a partner and solution provider, we advise customers and show them alternatives, allowing them to make the best decision. That’s precisely what we’ll be doing at GrindingHub 2022.”

Process monitoring during generating grinding of e-gear tooth systems
Although the design of transmissions in electric cars is simpler than that of conventional internal combustion engines, it places far higher demands on the manufacturing accuracy of the gears. Electric motors must deliver constant torque over a wide speed range at rotation speeds of up to 16,000 rpm. There is also another condition, as Friedrich Wölfel, head of Machine Sales at Kapp Niles points out: “Internal combustion engines mask transmission noise. Electric motors, on the other hand, are virtually silent. At speeds of 80 km/h and above, rolling and wind noise are the dominant factors, regardless of the powertrain. But in the range below that, transmission noise can become annoyingly noticeable in electric vehicles.”  The fine machining of these components therefore requires the use of a generating grinding process that is both productive and, above all, optimised in terms of the noise behaviour of the ground gear teeth. It is crucial to avoid so-called “ghost frequencies” which can be caused during component grinding as the result of an unfavorable machine and process design.

It takes much less time to grind gears than to take control measurements: this makes it impossible to inspect 100 percent of all components. The best approach, therefore, is to detect possible defects during the grinding process itself. Process monitoring is crucial here. “Numerous sensors and measuring systems that provide us with a wealth of signals and information are already built into the  machines,” explains Achim Stegner, head of Predevelopment. “We use these to assess the machining process and the expected quality level of each gear in real time in the gear grinding machines themselves. This allows order analysis to be conducted on noise-critical components in a similar way to the checks performed on an end-of-line test bench. In the future, gear grinding will provide significant added value by ensuring that the quality requirements for these components are met. As a GrindingHub exhibitor, we’re very excited by the innovative concept of the show.”

Developments in tool grinding technology
The tool grinding sector is having to meet ever greater challenges. On the one hand, more and more special tools are being produced in small batches, meaning that the process design up to the first in-spec part is gaining in importance from an economic point of view. On the other hand, the robustness and productivity of existing series processes must be continuously optimised so that they can hold their own against international competition even in high-wage countries. The Institute of Production Engineering and Machine Tools (IFW) in Hanover is pursuing several different avenues of research. The first step involves simulative mapping of the tool grinding process to support the process design. The simulation itself predicts the process force-related displacement of the ground blanks before the first cutting tool is produced, allowing this to be compensated for during grinding and thus avoiding any resulting geometric deviations. Furthermore, the load on the grinding tool is analysed, permitting optimum adaptation of the process planning to the grinding tool used. This improves the machining result and minimises the number of rejects.

“Laser-based sensor technology has also been installed in the machine tool to measure the grinding wheel topography. This helps maintain the superior machining quality even at higher volumes,” explains managing director Prof. Berend Denkena, who is also a board member of the WGP (German Academic Association for Production Technology). “This allows continuous evaluation of the grinding tool status. It means it can be used to determine dressing intervals for specific processes. This helps avoid deviations in workpiece geometry due to wear and associated rejects.”

Automation + digitalisation
“There has been a significant increase in the speed of grinding technology development in recent years. Advances in digitalisation are the main reason for this,” says Dr. Stefan Brand, managing director of the Vollmer Group in Biberach, commenting on the latest trends in grinding technology. “At Vollmer we have been using digitalisation in automation and data analysis for years now. We have developed our own IoT gateway that we are feeding more and more data into. The latest trend in grinding technology is the further integration of process data. The resulting knowledge gives users helpful insights into how the grinding process can be optimised. The journey into the digital future is constantly evolving. It is becoming clear how merging classic grinding technology with digital functions is not only influencing the grinding process itself, but also changing the market for grinding technology. Digital and automated processes are being used as optimisation levers by sharpening services, tool manufacturers and globally operating manufacturing companies alike.

“This development is one reason why the new GrindingHub trade show is focusing not only on automation and digitalisation in grinding technology but also on the areas of technology/processes and productivity. That’s why we welcome the opportunity to present our grinding technology to a broad and international audience at GrindingHub.”

Saw centre cuts the path to productivity with Vollmer

November 1st, 2021 10:11 am | by Admin

As a company that has roots that date back to 1889, The Saw Centre and its growth trajectory really took off when the company was bought by a father and son partnership in the late 60’s. The company has grown exponentially since then and it now employs more than 30 staff in a 20,000 sq/ft purpose-built facility. Now in its third generation of family ownership and jointly managed by David Stevenson and Tony Galbraith, the company has evolved with significant growth of its saw blade sharpening business bolstered with diversification into the sales and service of machinery for the wood, metal and UPVC sectors.

To expand the portfolio of services, the acquisition of a tooling service and manufacturing company in 2006 provided the staff with the skills and knowledge to service the needs of the precision engineering and panel processing industries. The purchase of a small tooling company enabled the Saw Centre to move work from traditional machines to a CNC grinding centre and subsequently become the only independent company in Scotland with this facility. However, the mainstay of the business remains as the name suggests, the Saw Centre – and it is here that grinding and sharpening machines from Vollmer have made a significant impact.

It was back in 2001 the company made its first major investment in Vollmer technology, purchasing a Vollmer CHD250R2 TCT saw blade sharpening machine and a Vollmer Loroch HSS saw sharpening machine that were both connected to a Vollmer ND automation centre. At the time, it was the first Vollmer automation station in the UK to simultaneously service both HSS and TCT saw blade sharpening machines. This investment provided The Saw Centre with the facility for 24/7 operation, ramping up productivity levels and capacity. Most impressive was that the automated cell eradicated the need for three HSS saw blade sharpening machines and an additional four TCT saw sharpening machines. The cell removed seven machines from the shop floor, reduced costs, as well as power and consumable consumption and enabled the company to allocate two staff to alternate tasks whilst adding significant sharpening capacity.

The latest investment
Despite working around the clock for 20 years, saw blade technology has evolved and this required a new solution. Joint managing director Tony Galbraith says: “The evolution of saw blades for our primary industries of wood, metal cutting, construction and UPVC has moved on quite drastically in the last 20 years. To service the needs of our customers and streamline our productivity, we needed to upgrade our machinery. This upgrade was the Vollmer CHD270 with an ND250 5-stack robot loading system that arrived in April 2021.

“As manufacturers strive to improve productivity and prolong saw blade life, the required geometries have become ever more complex. Unfortunately, the software, kinematics and machine movement of the old Vollmer CHD250R2 meant that we either had to undertake two or three setups to complete complex saw blades or we would subsequently subcontract the work out to another supplier. In some instances, we turned away the sharpening of certain blades. Now, we can regrind everything on the new CHD270 and when it comes to TCT saw blade sharpening, I wouldn’t go to anyone but Vollmer.”

The Vollmer CHD270 is a fully automated machine for the complete machining of Carbide Tipped (TCT) circular saw blades with eight CNC-controlled axes and measuring equipment. The machine design demonstrates excellent stability, takes up little space and is very easy to use. The entire grinding unit of the CHD270 is compactly and robustly mounted on a central monoblock main structure to take precision and smooth running to a new level. Furthermore, the patented twin grinding wheel concept provides complete machining without having to replace the grinding wheel. The ergonomic design makes the CHD270 very easy to operate and to access for maintenance work on the control cabinet, coolant pump, pneumatic system and fire extinguishing device. When combining this with the user-friendly ND250 automation system, you can have complete confidence in the ability to sharpen saw blades around the clock with impeccable quality and productivity levels.

The benefits of the CHD270
This confidence in Vollmer technology is justified by the impressive performance of the previous Vollmer CHD250R2 over two decades, but the new machine takes productivity, technology and automation to a new level. Discussing this, The Saw Centre’s factory manager Scott McQuillan, who has been with the company for 25 years, says: “In the last 20 years, saw blade geometries have evolved considerably in all industry sectors, as saw blade suppliers and their customers strive to improve performance and blade longevity. In the panel processing industries, the demand for hollow ground blades with concave tooth geometries has increased drastically. Used in wall saws and vertical panel saws, the blades require an excellent finish and as we are selling more of the machines and blades we had to find a more efficient way of grinding them, previously the blades would require two processes on two machines to get the quality we were looking for.”

The transfer of the blades between two machines resulted in a sharpening time of approximately 40 minutes, depending upon the blade size and type. Furthermore, these saw blades had to be manually loaded, increasing the workload for staff as the volume of blades continually increased. “With the new CHD270, we can now process the saw blades in a single automated setup in less than 20 minutes. Not only has this slashed our cycle times by 50 percent but it has also eliminated manual loading, as we can just put the blades into the ND250 robotic cell and forget about them.

“Going back 20 years, we did not have such a variety of machines using carbide-tipped blades and with all the new materials that are coming onto the market such as composites and processed board, we needed to have a system that could deal with all the geometries and with the new Vollmer CHD270 we can achieve endless saw blade geometries. This means that there is no saw blade we cannot sharpen and the need to inform a customer that we cannot service their blade has been completely eradicated, increasing our production and service capabilities.

“Blade manufacturers are continually increasing the geometry range of their saws and this is particularly prevalent in the UPVC and aluminium industry. We have some saws with a flat tooth geometry with side bevels that would previously be three operations and are now a single operation on the CHD270. Likewise, some saws would alternate teeth between flat and bevelled teeth. The CHD270 takes all this in its stride as it has all the tooth forms and geometries we could ever need, future-proofing our business from next-generation saw geometries that may come along in future.“

Additional benefits
The move from the ageing Vollmer CHD250R2 to the next generation CHD270 has gone far beyond extending flexibility and capacity at The Saw Centre. Scott McQuillan continues: “The new machine has a host of new features that really do highlight how Vollmer has evolved its technology over the last 20 years. The CHD270 software is more user friendly than ever before and we now have apprentices becoming very competent at setting the machine with minimal training. Likewise, the software for the ND250 robot loader has been improved too. Previously, if there was an issue with a saw blade in the middle of a stack, we would have to remove half of the stack and reload the stack. Now, the software allows us to remove individual blades from the processing cycle without re-stacking. Additionally, with the variety of portable plunge saws on the market, we now can stack blades that are under 180 mm. We spent 2-3 hours of each day manually loading the portable saw blades and now with the facility of stacking up to 70 at a time, we are gaining more time each day. The processing time has gone from 9 minutes to 6 minutes which in our factory, any time gained is a bonus.

The software, flexibility, kinematics and performance are much improved from the previous machine, but there is much more. The machine is more robust and the build quality has improved too. The probing and measuring system is second to none and it makes it near impossible to make errors, even the hydraulic oil system has been enhanced with a new pneumatic system that is cleaner and safer for our staff. Investing in the new Vollmer CHD270 will speed up our processing times and raise the quality that our customers need. It is not only an investment for us but it is a machine and a service that our customers deserve. We are extremely happy with our new Vollmer CHD270.”

Expert forum a magnet for visitors
Fraunhofer’s cleaning division organised the parts2clean forum, which provided a unique knowledge platform for all topics related to parts and surface cleaning. Hundreds attended the forum on-site and 1,500 participants joined online. Frank-Holm Rögner, division manager at Fraunhofer, reported, “We are extremely satisfied with the high level of participation in our forum, where we were able to welcome not only national but also international visitors. The number of visitors is lower overall than in 2019, but the quality is very good. The topics ‘challenges due to film contamination’ and ‘cleaning for medical and pharmaceutical technology’ were particularly well received. There was also strong interest in the areas of standardisation and guidelines and the exhibitor product presentations. The demand for up-to-date information is huge, which is a great position for the parts2clean forum.”

Samuel Wolf, assistance to the management, vapic GmbH, says: “As the leading trade fair for industrial parts cleaning, parts2clean has been the most important of all trade shows for us for years. What makes parts2clean special is that customers come with specific project ideas and want to develop solutions together on-site. Visitors demand a wide range of specialist knowledge to meet their requirements. We rate this year’s show just as successful as parts2clean 2019 and thank all visitors for their interest. We look forward to starting the new projects.”

Wolfgang Kaufmann, head of sales, Zippel GmbH, adds: “We were pleasantly surprised that on the morning of the first day we had many visitors at the stand. It was the best morning at the show so far. The other two days of the fair were also very well attended. Of course, we cannot compare the absolute number with 2019, but the visitors who were at parts2clean were specifically looking for solutions and were not only interested in our standard systems, but also in tailor-made solutions, which we manufacture completely customer-specific.”

The next parts2clean runs from 11 to 13 October 2022 in Stuttgart.

Enhancement to the range of cut-off wheels from Master Abrasives

November 1st, 2021 9:40 am | by Admin

New hot pressed cut-off wheels are Master branded

Master Abrasives has expanded its range of cut-off wheels by also offering hot pressed wheels as well as larger diameter cut-off wheels. The expansion of the Master range of cut-off wheels allows the company to offer better suited cut-off wheels to markets such as the foundry industry.

Managing director, Paul Batson states: “There has been a gap in the Master product offering in when it comes to both hot pressed wheels and larger cut-off wheels. This addition to the range provides our customers a more complete range of abrasive consumables from our economical range.”

Previously the Master range ,included cut-off wheels up to 300 mm in diameter. Now the range includes reinforced and non-reinforced wheels all the way up to 1700 mm. The hot pressed Master cut-off wheels are designed to provide efficient cutting of gates and risers in the foundry industry. These wheels are reinforced and they provide outstanding performance for most foundry cut-off applications but are exceptionally productive for the cutting of large gates and risers where heavy feed pressures or heat build-up within the cut make cold pressed wheels unsuitable. The wheels have rilled sides for cool, free-cutting action providing less operator fatigue and more cuts per hour. High-strength fibreglass is moulded into the wheels offering high resistance to breakage. The new hot pressed straight and depressed centre wheels are available for swing-frame and chop-stroke machines, with diameters ranging from 406.4 to 762 mm.

The new Master cut-off wheels are also available in Poland, mainland Europe and Mexico from Master Abrasives’ sister companies and through the company’s distributors throughout the rest of the world.
