Royal Grippex 20L Coolant-Actuated Bar Pullers

Royal Grippex 20L Coolant-Actuated Bar Pullers and Accessories

• The patented Grippex 20L CNC 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 unreliable ejectors and also allows the sub-spindle to swallow longer parts.
• Thick-walled heavy-duty construction helps to protect unit and allows it to be used at coolant pressures of up to 280 psi.
• Very high gripping force and smooth operation is achieved through a patented finger mechanism that pivots on two roller bearings. As little as 15 psi of coolant pressure is enough to enable the Grippex to pull a 210 lb. bar!
• Hardened finger inserts reduce wear and help the Grippex penetrate hard materials like stainless steel.
• Includes one set of Standard Fingers (3-1/8” cap) and one set of Inserts
