TAJMAC 620 CAM
Description
The 620 is a 20mm (.787”) automatic bar capacity Multi-spindle with an AC drive for both the spindle and feed. It has 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 620 to hold much tighter tolerances then your standard multi-spindle. It can be equipped with spindle stopping, eliminating secondary operations. It can also be equipped with an automatic bar loader or set up as a chucker.
