Application:

The HCL-04 is a compact, long-stroke power chuck designed for high-precision clamping in clean machining environments. With its closed-center body, this chuck is ideal for vertical and horizontal lathes where chip and coolant intrusion must be minimized. The extended jaw stroke provides added flexibility for gripping a wider range of part diameters, making it especially useful for smaller round workpieces that require deep or adaptable clamping.

Technical Features:

The HCL-04 features an impressive 12.1mm jaw stroke, providing enhanced range for small-part applications. Its closed-center body offers strong protection against internal contamination, maintaining stable gripping force and improving longevity. Designed with an M16 x 1.5 threading, this model ensures seamless compatibility with hydraulic cylinders and other system components. Constructed from high-grade alloy steel and balanced for high-speed operation, the HCL-04 delivers consistent performance with reduced vibration. It’s an ideal solution where space, speed, and clamping adaptability all matter.
