Application:

The HC Series Power Chuck is engineered for high-speed, closed-center clamping—making it ideal for vertical lathes and machining environments where chip and coolant intrusion must be minimized. With its sealed center design, this chuck prevents internal contamination, ensuring consistent clamping force and extended service life. Perfect for environments where cleanliness, reliability, and high RPM are critical, the HC Series is a trusted solution for precision turning operations.

Technical Features:

Designed with a closed-center body structure to prevent debris infiltration, the HC-12SE Series offers a jaw stroke range of up to 10.5mm and a maximum gripping force of up to 156kN. Balanced for high-speed performance, it supports top RPM ratings while minimizing vibration. The chuck body is manufactured from high-grade alloy steel for strength and durability, and it's compatible with standard hydraulic cylinders for seamless integration into existing setups.
