- Bar gripper - Set C/D-Ø43-90mm
Advantages:
- operation mode: rapid traverse 30 m / min
- accuracy: +/- 0.1 mm (zero dead stop)
- low setting-up time
- attach gripper jaws to the gripper
- incorporate the gripper jaws into the tool data and calibrate
- no surface damage to the round steels which are to be processed
- clamping shafts available in all sizes und designs
Operation mode:
After cutting the material to length, in rapid traverse the bar puller automatically pulls the bar for the next processing operation exactly to the desired measurement.
Position 1:
- Signal: stop spindel
- The bar gripper is positioned in rapid traverse at the spindle centre in front of the material
Position 2:
- bar gripper moves in linear rapid traverse (30 m / min.) with the appropriate jaws onto the bar (approx. 4 mm are sufficient for this)
- Signal: open feed automatically
Position 3:
- bar gripper has pulled the material in rapid traverse (30 m / min.) to the desired position
- Signal: close feed automatically
- bar gripper moves in linear direction in front of the bar
- Signal: rotate spindle (processing can start again)
