Applications / Spindle Tool Clamping

Disc springs are used in the tool clamps for spindle-driven metal-cutting machines, such as milling and grinding machines, as well as CNC machines.

They aim to affix the drill or milling tool in the collets of high-precision, high-speed spindles to ensure that this can operate in a highly precise. They boast excellent durability (Repetitive load over 2 million times).

The spindle collets are used to release the finished part and then firmly grasp the next one in place.

In precision CNC machines, the control of collet clamping force is a key factor in ensuring consistent part quality.

Insufficient force may result in slippage, while excessive force can cause deformation. For high-volume production, maintaining a consistent clamping force over extended cycles is essential.

OPTIMUM Disc springs provide consistent clamping force during tool changes. When actuated by a hydraulic cylinder, Stacked disc springs are compressed during collet opening and automatically apply a consistent clamping force on the part once released.

Optimum offers standard and customized disc springs solutions to meet the specific requirements of CNC spindle applications.
