Replacing Collet Pads Is Faster Than Replacing The Solid Collet


Master collets and pads can save time and money. Hardinge, the inventor of the S-pad concept, has a dedicated S-pad manufacturing cell enabling them to maintain stock availability on more than 1000 styles and sizes of pads. The style-S master collet, although originally designed for multi-spindle automatic screw machines, has many benefits to the CNC lathe operator. The collet pads can be changed much quicker than a standard collet, the cost is less and the pads require much less storage space. Standard pads are hardened and ground for a long life, while soft and semi-hard emergency pads are popular for boring to size on the machine for shorter runs and secondary work.

Hardinge's patented style-S pads can be changed without removing the master collet from the spindle, thus reducing changeover time. For example, on an eight-spindle automatic, all the pads can be changed in 15-30 minutes as compared to 2-3 hours that it would take to change the solid collets. Hardinge's dovetail anchor design securely holds the pad in place when the bar is closed and it cannot be dislodged. No other front-loading pad can make this claim. The Hardinge design eliminates sets screws or clamps that could wear or break, and there is never any pressure on the clamp. There are no holes in the OD of the master collet, or on the ID of the pads, resulting in maximum bearing on the workpiece and the spindle collet seat.

Hardinge provides stock delivery of most popular sizes, and quick turnaround for decimal sizes and specials. Style-S pads are available in S10, S12, S15, S16, S20, S22, S26, S30, S35, S40 and S50 sizes to fit Hardinge style-S master collets used in screw machines, CNC lathes and Hardinge collet chucks. Pads are available in round, hexagon and square with smooth or serrated order holes, and with special shapes.
