Application:

The HSL-06 is a precision wedge-style 3-jaw closed-center power chuck designed for turning applications that require extended jaw stroke and consistent clamping across varying workpiece sizes. Ideal for jobs that demand deeper clamping reach or long gripping surfaces, the HSL-06 delivers secure holding power in both high-speed and general-purpose machining environments.

Technical Features:

Built with a long-stroke design, the HSL-06 provides a jaw stroke of up to 20.2mm, enabling it to clamp a wider range of part diameters without frequent jaw changes. It delivers a maximum gripping force of 31.2kN and supports spindle speeds up to 4,500 RPM, maintaining high clamping reliability and performance at elevated speeds. The closed-center configuration minimizes internal contamination, helping to extend the chuck’s service life. Its hardened wedge mechanism ensures smooth force transmission, while compatibility with standard rotary hydraulic cylinders allows for seamless integration into most CNC lathe systems.
