The Jaw Type Hydraulic Chuck is designed for strong, reliable, and efficient workholding in demanding machining applications. Its built-in rotary cylinder eliminates the need for a separate draw tube or rotary cylinder, simplifying installation and operation. The extra-large piston provides high clamping force for secure and stable workpiece holding during machining.
The center through hole supports bar work and facilitates automatic feeding for improved production efficiency. It is also an ideal solution for converting conventional manual lathes into automated machining systems. Available in multiple models with different capacities, operating pressures, RPM ratings, clamp forces, and jaw sizes to suit various machining requirements.

Precision-engineered CNC & VMC machine toolings and accessories designed for reliable performance, accurate machining, and efficient industrial operations.
A jig’s primary purpose is to provide repeatability, accuracy, and interchange ability in the manufacturing of products. A jig is often confused with a fixture.
We make multi Head Spindle for the purpose of more than one hole at single operation at different P.C.D. as per your requirements with grease or oil.
The surface of metal parts worked through turning, reaming or boring operations is a succession of “PROJECTION or PEAKS” and “INDENTATION or VALLEY” when microscopically examined (see fig. 1).
The VMC Machine Spindle Cartridge is a precision belt-driven spindle unit designed for reliable and accurate machining performance. With spindle nose accuracy strictly maintained below 0.007 mm, it supports a wide range of machining operations.
The CNC Machine Spindle Cartridge is engineered for high precision, reliable performance, and long service life in CNC machining applications. Precision-ground components, high-accuracy bearings, and special lubrication ensure smooth and consistent spindle operation.
