Royal Grippex 20L Coolant-Actuated CNC Bar Pullers

  • The Royal Grippex 20L bar puller is actuated by a CNC lathe’s coolant system. As coolant is fed through the unit, it pushes a piston forward which causes the fingers to close around the bar stock. When the coolant is turned off, the fingers automatically spring open.
  • Self-adjusting mechanism – fingers will close down until they contact the bar stock so no presetting is necessary. This feature allows the Grippex to make multiple pulls on the same workpiece, even after the OD has been turned.
  • Unit can also be operated by air pressure.
  • When fitted with robot gripper jaws, the Grippex can:
    • Remove a bar remnant from a bar-fed lathe and drop it into the parts catcher. This eliminates the risk of the remnant falling into the chip conveyor where it can become jammed and cause damage.
    • Remove a finished workpiece from a sub-spindle and place it into the parts catcher. This eliminates the need for ejectors and also allows the sub-spindle to swallow longer parts.

Here’s how it works:

Step 1
Feed Grippex up to end of bar stock

Step 2
Coolant On (M-08) – Fingers close around bar stock

Step 3
Retract turret to desired position, pulling bar with it

Step 4
Coolant Off (M-09) – Fingers open

Step 5
Begin machining next part
