Ø400-500mm (compatible chuck Ø12-16)
The diameter of the rotary table is Ø400.
The extra-large through-hole diameter facilitates the design of automatic clamping fixtures.
The main spindle and radial and axial bearings are integrated into one structure.
The safe double-ring brake structure is pressure resistant to 5 MPa.
It adopts a high-efficiency, high-tooth-depth double-lead worm gear drive.
