The new “Y-axis” provides a vertical tool displacement of +/- 50 mm from the center of the main spindle. Thanks to this new option, the STH series are capable of carrying out more complex milling operations.
The movement is transmitted by an induction hardened ball screw with a hardness of 43 HRC. This carriage is guided by a dovetail.
With a maximum backlash of 0.01 mm, it is built with a servomotor with brake and synchronous belts. In addition to the motor brake, this set is equipped with a double hydraulic brake for rigid fixing.
