Description

The 632 32mm (1.250”) and 642 42mm (1.653”) are automatic bar capacity Multi-spindles with AC drives for the feed and optionally for the spindle drives allowing spindle speeds to be set  in 1 RPM increments. 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 a 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 632 & 642 to hold much tighter tolerances than your standard multi-spindle. These machines can also be equipped with spindle stopping, eliminating secondary operations. They can also be equipped with an automatic bar loader, or be set up as a chucker.
