High-Rigidity Spindle

Equipped with angular contact ball bearings at the front and double-row cylindrical roller bearings at the rear for powerful, precise cutting.

Superimposition Control

The sub-spindle (SP2) synchronizes with the turret to machine a workpiece in the main spindle (SP1), drastically reducing cycle times.
