ROYAL LOW-PROFILE ACCU-LENGTH™ CNC COLLET CHUCKS

Simple Design

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.

Spindle Bearing Protection

An oversized flange acts as a coolant slinger to protect lathe spindle bearings from contaminants.

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. Click here for additional information.

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.

Dead-Length Operation

Royal Quick-Grip™ Accu-Length™ CNC Collet Chucks incorporate dead‑length operation to eliminate part pullback. With this design, the collet is held stationary in the chuck body and a tapered sleeve pushes forward to compress it, resulting in precise z-axis workpiece positioning.

Specials

If you have a special application that goes beyond the scope of our standard line, we will be happy to design and build a custom system to meet your needs. Please contact us to discuss your requirements.

Outstanding Rigidity

All Royal Accu-Length™ Collet Chucks have been optimized for maximum rigidity, and all components are hardened for strength and durability.

Low-Profile

All external dimensions have been optimized to provide maximum tool clearance.

High Accuracy

All Royal Accu-Length™ CNC Collet Chucks are guaranteed to run within 0.0002" TIR.

Wide Range

Royal manufactures a wide range of Accu-Length™ Collet Chucks to fit all popular spindle noses and collet styles.

Easy Installation

All Royal Low-Profile Accu-Length™ Collet Chucks include a collet wrench, mounting hardware, mounting wrenches, and a custom-machined drawtube connector for hassle-free installation.

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.
  • In-stock for same-day shipping.

For capacities greater than 1.75", choose the appropriate Royal Quick-Grip™ CNC Collet Chucks.  Quick-Grip™ CNC Collet Chucks offer many advantages over Low-Profile Collet Chucks, including superior tool clearance, parallel-grip functionality, and better price-points.

If you would like to continue utilizing older technology S-type collet pads, you can do so with the use of our Quick-Grip™ master collets.
