      ZPS 657/67 CAM

      The 657 57mm (2.250”) and 667 67mm (2.625”) automatic bar capacity Multi-spindles come with an AC drive for both the spindle and feed. The 657 can optionally have a second AC spindle drive allowing each station to choose the optimal RPM for the machining operations performed In each position. There are 6 cross slides, 6 end working slides, and 4 Longitudinal slides in the 1, 2, 4 and 5 positions.  Using the longitudinal slides in conjunction with the cross slides will create two axis movement in these 4 positions, and optionally, can be controlled by CNC for more complex shapes. The slides are independently cammed for optimum feed rates for each position. The spindle carriage is manufactured with a high precision face gear lock up that allows the 657 and 667 to hold much tighter tolerances than your standard multi-spindle. The 657 can also be equipped with spindle stopping, eliminating secondary operations. The 657 and 667 can also can be equipped with an automatic bar loader or set up as a chucker.
