Super-GripTM Bidirectional Serration 

Specifically designed for NC turning centers, Superior's Super-GripTM bidirectional collet pads feature serration lands which penetrate the work for a positive gripping action. This unique and exclusive pyramid configuration provides equal gripping force along the spindle axis in both forward and reverse spindle rotation. It also assures smooth bar feeding while precluding "push back" resulting from the cutting forces. Super-GripTM collet pads are ideally suited for exotic or hard materials such as inconel, stainless...and many others.

Martin Pads

Identified by the largest diameter being in the middle separating two ground diameters of equal size. Square lugs are threaded into the periphery of the ground diameter closest to the face of the master collet. By turning the set screws, the lugs expand into slots  thus securing the pad to the master collet. These pads are used primarily on multi-spindle automatics but are used in some collet chucks. 

Pros: 

bullet

Easy to change pads without removing master collet from chuck.

bullet

Manufactured by several manufacturers,

Cons:

bullet

Have become less popular in recent years.

 


Explanation of  Superior Part Numbers

Superior part numbers are in the form:

XXXX-XXX-XXXX

The first four digits represent the series number. The middle three describe the ID as follows:

  200 - Round Smooth

  201 - Round Serrated

  202 - Hex Smooth

  203 - Square Smooth

  204 - Hex Serrated

  205 - Square Serrated

  206 - Soft Emergency 

The last four digits represents  the size number which can be determined by multiplying the decimal equivalent of the size in inches by 1000.

For example,

1026-203-1250

is a 1-1/4", square smooth,  series 1026 collet pad.
