Cemented Carbide Cutting Die Introduction

Cemented carbide cutting die is standard toosl for processing and trimming thread. The basic structure of the cutting die is a nut, axially out of the holes to form in front of the cutting teeth of the chip. Simple structure, easy to use,cutting dies in small batch production applications is very broad.

Taps for processing the internal thread, the external thread used with this relative machining tool is a circular die. Circular die structure is shown in FIG. The left and right end faces of the circular die are getting the cutting cone angle 2Ф, after the formation of the addendum by grinding the angle.

Circular die where longer part of the side of the cutting (cutting cone), said that this side is positive, write the name, grade, material grades and manufacturers ".

The rake angle of the circular die, the function of the chip flutes, the cutting portion, the rear corner and the tap is the same, but the mutual positional relationship with the workpiece tap opposite. The chips discharged from the cutting edge around the hole.
