Bar Feeder complements high-speed CNC lathes.

Press Release Summary:

Equipped with 300 mm, sloping plane, multi-bar magazine, TAL 65 feeds bars from 5-65 mm at 250-500 mm/sec. Dual bar support principle uses hydraulic immersion and dynamic support in elastic guide channel to provide high-speed feeding, even when bars are slightly bent. Closed-loop re-circulating oil system feeds oil into elastic guide channels, eliminating bar vibration. Mechanical traction-designed system with hydraulic clutch allows total adjustment of force.

IEMCA TAL 65 Ideal Match For High-Speed CNC Lathes

ST. LOUIS, MO - The IEMCA TAL 65 bar feeder is designed for feeding high-speed automatics and is particularly well suited for CNC lathes. The TAL 65 is the ideal choice for feeding bars from 5 to 65 mm. Particularly well suited for high-volume production, the TAL 65 is equipped with a uniquely designed 300 mm sloping plane multi-bar magazine for continuous automatic feeding - a feature that can dramatically increase the productive output of conventional CNC equipment.

A dual bar support principle utilizes hydraulic immersion and dynamic support in an elastic guide channel to provide high-speed bar feeding even when bars are slightly bent or irregular (bar straightness requirement is typically 0.5 mm/m).

The TAL 65 is designed for quick bar changes - as little as 25 seconds for 12 ft bars - and ease in setup. Feeding speed is 250 to 500 mm/second. Return speed is 500 mm/second. A patented system of double feeding reduces overall bar feed length - to just 350 mm longer than bar length. Ultra-quiet, virtually vibration-free operation results from patented elastic guide channels made of tough, wear-resistant spring steel incorporating a special elastic polymer for unprecedented mechanical endurance. A closed-loop re-circulating oil system feeds oil into the elastic guide channels, eliminating bar vibration. A front vibration dampening device bushing between the feeder and lathe is equipped with a Vulkollan bushing whose diameter is very close to the bar size being machined. The system is lubricated by continuous oil bath and opens to allow the pusher through. This system stops bar vibration from passing into the lathe spindle and improves component machining accuracy. By changing just the bushing, the need to change channels, even outside their normal bar range, is most times unnecessary.

A mechanical traction-designed system with hydraulic clutch allows total adjustment of force, thus feed pressure is supplied only when required at the collet opening. A special track system allows the feeder to be easily retracted along the loading axis to provide maximum access to the lathe spindle for maintenance or repair. The feeder then can be moved quickly and easily back to its original position and secured without loss of alignment to the lathe.

For more than 40 years, IEMCA has been an industry leader in the design and manufacture of automated feeding systems for both single- and multi-spindle lathes, and has built a reputation for innovation and unparalleled service and support. The company continues to offer the most comprehensive product range in the automated feeding systems marketplace. Hydromat, Inc., is the exclusive North American distributor of IEMCA Advanced Feeding Systems.
