Collet chucks changed automatically, on
demand
In an integrated pick-up spindle cell demonstration, the automatic, robotic changing of collet chucks will be used to adapt the machines for machining three different components.
Hainbuch precision collet chucks supplied by award winning workholding specialist Leader Chuck Systems will be among the star attractions at the EMO Encore being staged by Yamazaki Mazak U.K at its Worcester, UK, site on 24-27 February 2004

Precision chucks and accurate turning make money
A turning centre fitted with precision collet chucks on its main- and sub-spindles is central to a subcontractor's successful policy of machining small batches of precise, complex parts.
Hydraulic tool holders made for high speed
Latest hydraulic tool holding range is suitable for high speed and high precision machining operations, such as milling, drilling, reaming, boring and engraving.
Quick-change chuck speeds changeovers
Capable of fast changeovers, a collet chuck has a runout accuracy of only five microns and is a replacement for other styles of collet chucks in bar-fed turning applications.
The three Hainbuch chucks will be fitted to a pair of Mazak IVS 200 inverted spindle vertical lathes.
For the first time in the UK, these will be arranged as an integrated cell linked by conveyor system and robot handling to demonstrate highly-productive machining of three different workpieces.
Two components will be machined independently and simultaneously on each machine, having been loaded by the robot that will invert them between first and second operations.
First and second operations on the third component will be shared between the two machines.
Each workpiece requires different collet sizes and these will be automatically changed using the robot to place the required Hainbuch collet on to a pallet on the conveyor system, which will carry it to the machine loading system.
After depositing the previous collet on to an unload pallet, the robot will load the new collet.
Hainbuch collet-style chucks boast high-accuracy clamping of up to 0.004mm TIR and higher clamping forces - up to 50 per cent more, with the same drawbar pull - than a conventional jaw or collet chuck.
The chucks differ from standard chucks in being able to also securely hold short component lengths.
This is due to their positive pull-back and clamping action, where the clamping head is pulled into a perfectly mating taper.
The cell demonstration by Yamazaki Mazak U.K.
was first staged at EMO 2003, then at the company's site in Germany before being scheduled for its UK debut at Mazak's EMO Encore.
The recently introduced inverted spindle IVS 200 lathe is a 26kW/7,000 revs/min machine with unload and transfer speeds of 110m/min.
