Description

The 832 (1.250″) and 842 (1.653″) automatic bar capacity Multi-spindles have an AC drive for the feed, and optionally, for the spindle drive allowing spindle speed to be set  in 1 RPM increments. There are 8 cross slides, 8 end working slides and 4 Longitudinal slides in the 1,2,5 and 6 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 832 & 842 to hold much tighter tolerances then your standard multi-spindle. These machines can also be equipped with spindle stopping, eliminating secondary operations.
