Royal Quick-Grip™ Pullback CNC Collet Chucks
Features:
- Traditional pullback design – collet is pulled into chuck to close, pushed out to open.
- No collet stop capability, therefore this chuck style is typically used only on jobs where holding precise axial position is not critical.
- Includes many of the same features of our QG Accu-Length™ models, including:
- 10-second collet changes
- 0.0002" TIR accuracy on closing angle
- Wide 0.062" collet range
- Compact dimensions for superior clearance
Bolt & Go™
- Our exclusive Bolt & Go™ mounting feature is standard on all Royal Quick-Grip™ Collet Chuck models. Bolt & Go™ enables chucks to be mounted very quickly and ensures maximum accuracy and rigidity.
Extremely Fast Collet Changes
- Changing collets on a Royal Quick-Grip™ CNC Collet Chuck takes just a few seconds. A unique hook and groove design for securing collets is used instead of traditional threads.
Wide Gripping Range
- Royal Quick-Grip™ Collets have a 0.062" gripping range (+/- 0.031"), enabling them to accommodate undersized and oversized bar stock.
Completely Sealed
- Lubricated for life, these chucks incorporate multiple O-ring seals to keep contaminants out and prevent chip pack-up on bore-thru applications.
High Accuracy
- Royal Quick-Grip™ CNC Collet Chucks are very accurate – runout on the closing angle is guaranteed to be within 0.0002" TIR.
High RPM
- All Royal Quick-Grip™ Collet Chucks are balanced by design for high-speed operation, and can often be run at higher speeds than conventional 3-jaw chucks because they are less affected by centrifugal force.
Low-Profile
- Royal Quick-Grip™ CNC Collet Chucks have smaller nose diameters than other quick-change collet chucks for superior tool clearance.
Coolant Slinger
- All bodies incorporate an oversized flange to protect the machine tool spindle bearings from coolant penetration.
Collet Compatibility
- Royal Quick-Grip™ Collet Chucks can sometimes utilize other brands of quick-change collets. Call Royal to verify.
Shortest Length
- Royal Quick-Grip™ CNC Collet Chucks are among the shortest chucks available, providing maximum work envelope utilization. This is especially important for smaller machines with limited z-axis travel.
Heavy-Duty Construction
- All chuck components, including the drawtube connector, are hardened to Rc 61-63 for high rigidity and durability.
Easy Installation
- Royal Quick-Grip™ Collet Chucks include all mounting hardware, mounting wrenches, and a custom machined drawtube connector to ensure hassle-free installation.
