Suitable for CNC lathes, (internal and external) cylindrical grinders and surface grinders, and specialized machinery.

1.Repeatability of grip precision ≦5u; the chuck is installed in front and back of the spindle nose screw and calibrated.

2. The main body spring leaf is integrally formed, and therefore there is no wearing by repeated sliding; may be used for both outer grip and inner expansion grip.

3. Thin and short workpieces are easily deformed during grinding and turning; the pneumatic pressure may be adjusted for machining at pressures below 0.5/kg.

4. Fragile ceramic, graphite, carbon columns, spindle sleeves, optical aluminum pieces, laser machining, etc.

5. Completely waterproof and dustproof; light cutting, high RPM, and high precision.
