Extrusion Taps

The extrusion taps - cold extrusion chipless machining "is a new internal thread processing method: extrusion tap prefabricated piece bottom, cold extrusion method, the workpiece to produce plastic deformation thereby forming an internal thread. Extrusion taps to open the chip flutes, nor cutting edge. Cold extrusion chipless machining to complete the ordinary cutting tap competent internal thread processing, the degree of attention and this process is increasingly widespread.

Its main advantages are:

1) organized threaded surface after extrusion, abrasion resistance is improved. The tapping spreading a small amount the thread surface squeezed light to improve the accuracy of the thread.

2) High speed tapping chip removal high productivity.

3) Taps strength, not easy to break, and long life.

Extrusion tap is mainly applied to a high-precision, high strength plastic material, suitable for the specific machine or automatic production line use.

Pictured is squeeze taps structure. The large diameter of the cutting part of the tracks, tracks make positive cone angle, tapping the first tooth tip to squeeze into, and gradually expanded to all the teeth, and finally squeezed thread toothed. The ends of the cross-section of the extrusion taps were a multi-prism, to buccal less contact surface and reduce torque.

Extrusion Tap

Extrusion tap diameter than ordinary tap should be an additional amount of elastic recovery, often take 0.01p. Extrusion taps diameter, pitch and other parameters of high precision manufacturing.

The extrusion tap selection, pre-drilled hole diameter desirability bottom of the thread diameter plus an amount of correction. The amount of correction values and the workpiece material, process test required by the decision.
