Royal Low-Profile Accu-Length™ CNC Collet Chucks
- These chucks utilize spring-type collets and therefore do not provide the parallel grip functionality or wide gripping range of our Quick-Grip™ models.
- Dead-length operation - sleeve pushes forward to compress the collet, providing precise z-axis part positioning.
- Low-profile nose offers outstanding tool clearance.
High RPM
- All Royal CNC 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 prone to the negative effects of centrifugal force.
Dead-Length Operation
- Royal Accu-Length™ CNC Collet Chucks incorporate dead-length operation to eliminate part pullback. With this design, a tapered sleeve pushes forward over the collet to compress it, resulting in precise z-axis positioning.
Outstanding Rigidity
- All Royal Accu-Length™ Collet Chucks have been optimized for maximum rigidity, and all components are hardened for strength and durability.
Spindle Bearing Protection
- An oversized flange acts as a coolant slinger to protect lathe spindle bearings from contaminants.
Low-Profile
- All external dimensions have been optimized to provide maximum tool clearance.
Bolt & Go™
- Our exclusive Bolt & Go™ mounting feature is standard on all Royal Low-Profile Collet Chuck models. Bolt & Go™ enables chucks to be mounted very quickly and ensures maximum accuracy and rigidity.
High Accuracy
- All Royal Accu-Length™ CNC Collet Chucks are guaranteed to run within 0.0002" TIR.
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.
Easy Installation
- All Royal Low-Profile Collet Chucks include a collet wrench, lubricator, mounting hardware, mounting wrenches, and a custom-machined drawtube connector for hassle-free installation.
Wide Range
- Royal manufactures a wide range of Accu-Length™ Collet Chucks to fit all popular spindle noses and collet styles.
