GE certification adds to aerospace surface finishing ambitions
OTEC stream finishing machines have been used to create bespoke surface finishing processes for aerospace component manufacturers
Fintek has gained GE certification for mass surface finishing. Adding to its existing AS9100 and AS9001, the new certificate is an important milestone for the company as it continues to expand its subcontract surface finishing services in the aerospace sector.
Fintek is engaged in pioneering work with several aerospace component manufacturers, working closely with them to eliminate production bottlenecks where hand and traditional finishing methods are not able to achieve higher quality surface finishing requirements in shorter times.
Of particular concern for many aerospace parts manufacturers is unseen damage caused by manual deburring using small powered hand tools. These can sometimes cause accidental nicks that can compromise fatigue requirements, possibly with catastrophic consequences. Another hand finishing issue is that missed burrs are subsequently peened over. Again, these can become sources of component failure.
Key to addressing these issues has been the introduction of highly controllable stream finishing systems by OTEC Präzisionsfinish GmbH. Fintek represents OTEC in the UK and has been able to develop special processes to dramatically improve the efficiency and, importantly, the quality of the surface finishing for aerospace manufacturers. Typical components benefiting from superior and more consistent surface finishing include turbine blades, extremely thin parts, gear wheels, fasteners and even cutting tools.
To accommodate additional stream finishing units and meet demand for these processes, Fintek is planning to extend its existing facility. “These are exciting times as much of the research and development work we have undertaken with F1 teams, the pinnacle of motorsport, is proving to be adaptable to aerospace and we can offer manufacturers mass finishing options to boost productivity and quality where previously they did not exist. This GE certification is another step forward for us,” says managing director Jonathan Dean.
Advanced heat treatments and hard coatings at Made in the Midlands
Stand L22 at the Made in the Midlands Expo 2019, June 20 will see Wallwork Group showcase a range of heat treatment and ultra-hard coating services. “The midlands and surrounding area represents a significant customer base, so we are pleased to be exhibiting again at MIM in its 10th anniversary year. Wallwork Birmingham, based in Smallheath, is one of our busiest group members,” comments Howard Maher, sales manager.
Being close to the UK’s huge motorsport cluster, means Wallwork’s expertise in highly controlled metal component heat treatments and precision plasma vapour deposition (PVD) and diamond-like coatings, is sought out by top racing teams.
With AS9100 accreditation and many aerospace prime approvals, the company is also a significant supplier to the aerospace industry. Recent Group investments at Birmingham include additional capacity for the processing of aluminium components as well as more vacuum furnaces.
“While aerospace and motorsport are the glamour industries, we also undertake a vast amount of work for general and precision engineering contractors of all sizes and specialisms. These can include tooling, prototypes, small batch work through to high volume needs,” adds Howard Maher.
Following the 2017 acquisition of the Metaltech business, the company has also established the processes of Xylan Fluoropolymer coatings and Molybdenum Disulphide dry film lubricants at other Group locations.
Highly skilled metallurgists and skilled surface engineers along with full laboratory and substantial in-house testing facilities, enables Wallwork to provide a quality service. A dedicated, national fleet of over 50 commercial vehicles ensures end-to-end speedy order turnaround.
