A new line of high-accuracy tool-holders designed to undertake milling, drilling, reaming and tapping operations while maintaining a near-perfect run-out — 0.003mm at 3xD — has been introduced by Widia.
Available in the UK from Tamworth-based Industrial Tooling Corporation Ltd (
www.itc-ltd.co.uk), these collet chucks feature a thick wall and a strong outer form that optimises rigidity and minimises vibration, thereby extending spindle life and tool life. Moreover, they feature a seal that has been designed to provide excellent coolant delivery, again extending tool life.
Furthermore, these collet chucks are available with Haimer’s Safe-Lock pull-out protection system, which is of particular use to manufacturers cutting high-strength difficult-to-machine materials that require the use of high torques and result in high cutting forces.
Helical grooves around the shank prevent the tool from spinning or being pulled out of the holder under extreme machining conditions. Furthermore, these helical grooves allow the operator to adjust the tool length, which means that tools can be reground and pre-set.
