CNC Rotary Table
ø320
GXA-320H
Worktable diameter Ø255, Ø320, Ø400.
Big spindle bore allow the more complex parts clamping and fixture.
Ultra high clamping force by drum brake system.
Consolidated spindle with radial-Axial bearing built-in.
Full gear depth transmitted by dual lead worm drive, resulting in higher efficiency and lower backlash.
