Double taper expansion collets


Double taper expansion collets, Spring Collets Double taper expansion collets are standard form as expansion collets for inside diameter clamping type. It is made to be expanded by drawing the central part of the collet with a drawbar, and clamp a workpiece.
These collets open in parallel since there are flexing slots from both sides of front and back.
According to the form of these collets, a little more clamping range in a free state can be taken.

Single taper expansion collets


Single taper expansion collets Single taper expansion collets are used for primary processing, such as NC lathe, in many cases.

It is made to be expanded by drawing the central part of the collet with drawbar, and clamp a workpiece.

These collets open in parallel since there are flexing slots from both sides of front and back.

High precision is expectable as compared with double taper expansion collets.

Flange type expansion collets


Flange type expansion collets

These are expansion collets with flange. It is made to be expanded by drawing the central part of the collet with a drawbar, and clamp a workpiece.

These collets may not open in parallel in case of the specification that the bore of the collet is opened widely in a free state since one side of the collet is a flange.

It’s easy to insert a workpiece since more clamping range in a free state can be taken.

Expansion disk


Expansion disk

Expansion disk is used for the gear cutting machine along with the tan line collets, and is indispensable to processing of differential gear of cars.

Expansion disk has the structure faces two plates together face to face and makes an outside diameter extend by compressing, and clamp a workpiece.
