Grippex Coolant-Actuated Bar Pullers

Royal Products has introduced the Grippex 20L CNC bar pullers, which are actuated by a CNC lathe's coolant system. Bar pullers can be used to automate any CNC lathe or turning center and improve productivity by enabling CNC lathes to run unattended, freeing up operators to handle other tasks. "Royal CNC bar pullers are inexpensive, require minimal set-up and can be easily fit onto any CNC lathe," said a company spokesperson.

Features of the Grippex 20L CNC bar pullers:

  • 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 O.D. has been turned.
  • Unit can also be operated by air pressure.

When fitted with robot gripper jaws, the Grippex can:

  • Remove a bar remnant for a bar-fed lathe and drop it into the parts catcher. This eliminates the risk of the remnant falling to 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 unreliable ejectors and also allows the sub-spindle to swallow longer parts.
