Vcenter-AX350

h Trunnion type tilting table (A+C axes) with innovative non-backlash rollercam mechanism
offers excellent solution for small part machining.
h Higher rotating speed and machining accuracy than conventional worm gear mechanism
shorten cycle time.

h Higher clamping rigidity than DD motor facilitates 4+1 axis heavy cutting.
hBT-40 spindle 12000rpm (15kW).
