Leader provides the drive to improve productivity with Tecnologie FRB
Established in Italy in the early 1960s, Tecnologie FRB designs and manufactures live centres and face drivers for turning, gear cutting, and grinding applications. The company has built an enviable global reputation in this sector, and its comprehensive product ranges are now available in the UK and Eire from workholding and ancillary manufacturing product specialist, Leader Chuck International.
Products started with the FRB patented 65, 80 and 85 live centre series with axial load distribution, and continuous research and development has resulted in the more recent series of 2000, 2006 for high-speed turning, and 2008 for hard turning. With high quality steel integral shafts available with or without carbide tips, interchangeable inserts and cone shaped heads means Tecnologie FRB’s live centres offer a tangible solution to manufacturing industries’ requirements.
A complete range of revolving live centres is available, equipped with morse tapers in different sizes, both with standard and special features to fulfil most requirements.
The company’s constant quest for innovation has seen it excel in a wide range of mechanical processing, from conventional and CNC turning and gear cutting to the more demanding cylindrical grinding and tooth grinding applications.
Live centres for grinding are in the 92 series and include the models for pipe grinding and the dead centre series for hard metal applications. For gear cutting the 82 series live centres provide axial and radial load with roller bearings.
A comprehensive range of face drivers for turning, grinding and gear cutting applications is also offered, with FRB having developed its first model back in 1965. “The range of face drivers can fit any workpiece holder from 5 mm to over 300 mm diameter,” explains Leader Chucks MD Mark Jones. From the classic spring-operated system, right up to the most advanced hydraulically powered system. FRB patented balancing and holding system, which is completely mechanical and technologically state-of-the-art, always guarantees absolute reliability, constant repeatability of results and unparalleled holding capacity.”
Thanks to the introduction of face drivers, turning and grinding processes have undergone a number of innovative improvements that have resulted in shorter cycle times for many workshops. The driver acts directly on the workpiece so the cutting tool or abrasive wheel has increased access to the whole part. With none of the raw material being held in a chuck or similar device it is often possible to finish parts in one hit, minimising any potential datum errors from repositioning for second operations and so on.
