Information about Master Collets & S-Type Pads for Low-Profile Collet Chucks

• For low-profile collet chucks with a capacity greater than 1-3/4", a master collet and pad arrangement is typically used instead of dedicated solid collets. The primary reason for this is to reduce operating costs for the customer – collet pads are less expensive than large solid collets.
  
  
• Royal low-profile CNC Collet Chucks utilize proprietary master collets that accept industry-standard S-type collet pads.
  
  
• These S-type pads are available hardened and ground to a specific size, or in the soft state which enables them to be machined to size by the customer.
  
  
• The pads attach to the master collet via special clamp screws. As a clamp screw is tightened, the opposing ends draw together, engaging a dovetail on the back of the collet pad and seating it securely in the master collet.
  
  
• All Royal Accu-Length™ S-Type CNC Collet Chucks include a master collet with multiple keyways for fine adjustability – a feature that is especially useful on subspindle applications.
  
  
• S-type master collet and pad assemblies are usually less accurate than a hardened and ground solid collet due to the tolerances of the pad/collet interface. S-type pad manufacturers usually state an accuracy in the range of 0.002" – 0.005" TIR.
    - For first operation work, this accuracy is fine because all surfaces that are turned in the same chucking will always be concentric to each other.
    - For second-op and sub-spindle applications where accuracies of 0.0005" TIR or better are required, we recommend either boring a set of soft pads to size, or ordering one of      our custom-made hardened and ground solid collets.

• All Royal S-type CNC collet chucks include one master collet and one set of pad clamps.
  
  
• Many shops keep an extra master collet on hand so they can install the collet pads for the next job ahead of time, reducing setup changeover times.
  
  
• All Royal master collets designed for our Low-Profile Accu-Length™ chucks include an internal thread to allow for the use of a part stop or ejector.
  
  
• Royal master collets are designed for use with Royal CNC collet chucks, but may also fit other chuck brands. Please contact a Royal applications engineer for additional information.

An Important Note About Royal Master Collets

• Royal Products is unique due to the fact that we design and manufacture all of our own low-profile master collets in-house. Having 100% control over the quality, delivery, and pricing gives us a significant advantage over our competitors who must purchase their master collets from outside sources and mark them up before reselling them to you.
