This machine is designed for duplex milling of Aluminium housings with component loading and unloading done manually. The machine has twin spindle assemblies and they are mounted on individual spindle housings, which   move in opposing directions on LM guide ways fitted on the machine frame. The spindle slides are driven by servo motors through set of ball screw and timer pulleys. The spindles are run by induction motors through inline couplings.  The aluminium component is carried in a fixture mounted on a central slide unit. The fixture slide is fed in between the cutters for milling operation on both the faces of the component simultaneously. The parallelity achieved is less than 8 microns
