Ultra-Precision Accuracy – 0.0002" or Better

While many users purchase the Royal Quick-Grip™ CNC Collet Chuck for its lightning-fast collet changes and wide gripping range, another major benefit of this system is its extreme accuracy. With CNC collet chucks, there are several factors which affect overall system accuracy. These include:

  • Accuracy and tolerance of chuck mount (taper angle, gage line diameter, squareness of mounting flange, etc)
  • Tolerance and fit between chuck components (body to mounting adapter, closing sleeve to chuck bore, etc.)
  • Accuracy and tolerance of collets (OD collet angle, bore sizing, concentricity of ID to OD, etc.)

The manufacturing processes for Royal CNC collet chucks and collets have all been fully optimized to achieve the absolute tightest tolerances and highest accuracies. While we guarantee our chucks at 0.0002″ TIR between the A-mount taper and collet chuck closing sleeve, they often run at 0.00005″ or better! Round-bore collet accuracy is also guaranteed to be within 0.0002″ TIR. This means that out of the box, with absolutely no indicating in, you can expect to achieve a Quick-Grip™ total system accuracy of 0.0004″ TIR or better. We know of no other collet chuck manufacturer that can consistently produce such an exact level of precision.

Parallel-Grip Collets with a .062" Range

QG adv

Royal Quick-Grip™ Collets have a much wider collapse range than conventional spring collets. A spring-type collet can only be compressed by up to 0.005″ before there is a sharp drop off in both grip force and accuracy due to the changing angle of the gripping surface. However, with the unique design of the Quick-Grip™ collet, each collet segment is joined to the adjacent segments with vulcanized rubber. This ensures that the collet segments always remain parallel to the workpiece as the collet is compressed, giving the Quick-Grip™ collet a full collapse range of .062″ (nominal diameter +/- .031).

Advantages of this system include:

The ability to compensate for oversized and undersized bar stock. Superior accuracy and grip force – by remaining parallel to the workpiece, each collet segment makes contact over its entire length. With a spring-type collet, over-collapsing results in just a narrow ring of contact near the collet face.

Advantages:

  • Incorporates many of the same features as our Accu-Length™ Quick-Grip™ CNC Collet Chucks, except that the collet is not fixed – it moves axially upon opening and closing.
  • Able to accept QG standard and extra-depth stop assemblies for locating parts.
  • This chuck is ideal for high-volume, robot-load applications in which the part needs to locate against a shoulder and air-sensing / position confirmation is required.
  • A great choice for any CNC lathe equipped with a servo-driven bar feeder.
  • Can be used either with or without the internal stop for both first and second-operations.
  • Standard collet stop assembly included with chuck
