We have manufactured a 3 axes CNC controlled Horizontal Mill/Drill Machine. The 3 liner slides are driven by Siemens make – Sinamics Motors in combination with ball screw and ball nut. The motors are controlled by Sinumerik 808D advanced controller. The ram type milling head mounted on the vertical carriage has extra rigidity than conventional slide mounted milling head due to its square box design locked in with taper jibs.
