Royal CNC 20S Coolant Actuated bar pullers 43340, 43345 can be used to easily automate any CNC lathe or turning center. The patented Grippex 20S 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. 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 work piece, even after the OD has been turned.
Thick-walled heavy-duty construction helps to protect unit and allows it to be used at coolant pressures of up to 140 psi. Very high gripping force and smooth operation is achieved through a patented finger mechanism that pivots on two roller bearings. Three-finger design is superior for gripping both round and hex stock.
- Same great features as Model 20L
- Smaller body diameter enables 20S units to be used on machines with less tool clearance and smaller turrets
- Actuated by a CNC lathe's coolant system or air pressure
- Self-adjusting mechanism - fingers will close down until they contact the bar stock so no presetting is necessary
- Hardened finger inserts reduce wear and help the Grip hard materials
- Gripping force for the 20S is quite high, but not as high as the 20L models (see chart)
- 140 psi maximum coolant pressure
- Available in 1" Shank or 1 1/4" Shank
