SE

Build-in hydraulic cylinder; it can also work with a lock valve and be driven by air pressure.
Radial clamp and axial pull down at the same time, keep the workpiece attaching close to the base surface of the chuck.
Almost no workpiece uplifting displacement.
3 jaw drill chuck which the body with heat treatment and the organization of cylinder pull-down, and fine boring, which guarantee the high clamping precision and durableness, it’s suitable for heavy duty machining.
3 jaw chucks are suitable for drilling, milling, and other machines.

Can work together with multi-plate.

Equipped with Airtight pressure detection function.
