BAR PULLERS



 FEATURES & BENEFITS:
  • Pulls bar to last usable part length
  • Pull positions bar +/- 0.001"
  • Eliminates Expensive bar feeds
  • Works close to chuck or collet nose
  • Does not interfere with adjacent tools or turret movement
  • Only 1/4" bar engagement required
The DUNHAM BAR-PULL line of low cost bar stock pullers for CNC lathes has been expanded to incorporate grippers in 1/16" increments from 3/16" 6 to 1" and in 1/8" increments from 1 1/8" to 2".

Kit #7 Special Kit for CNC Lathes
10 Grippers (3/16" to 3/4" in 1/8" increments); all grippers mount directly to Bar Pull Shank PB0625GT, no adapters required (this kit only); Bar Pull Shank PB0625GT (5/8" GT) included (this kit only).
HOW IT WORKS...
  1. Mount shank in turret; screw on adapter (if required) and gripper.
  2. Insert bar through back of spindle and clamp with collet or chuck
  3. Face off minimum 1/4" projection using parting off command in CNC program.
  4. Index turret to Bar-Pull and traverse turret toward spindle for programmed distance, sliding gripper over stock.
  5. Release clamping pressure on bar.
  6. Retract turret programmed distance.
  7. Reclamp Bar.
  8. Retract turret sufficiently to clear gripper from bar.
  9. Begin programmed machining cycle.
  10. Repeat until all of bar is used.
