So-called cemented carbide chaser is as if the four circular die tooth a separate, composed of a group of four.

Cemented carbide thread chasers use mounted in the die shoe. The finished thread die holder will automatically chaser opened from the outside, eliminating the need for the withdrawal of step with circular die processing thread.

Cemented carbide chasers with the workpiece contacting method, viewed from the outer radial, tangential and round three, can be divided.

Kinds of Cemented Carbide Chaser
Radial Cemented Carbide Chaser	Tangential Cemented Carbide Thread Chaser	Circular Cemented Carbide Chaser
The cutting edge and the material to be cut-contact manner is similar with turning tools or cutting dies.	Chasers repeatedly grinding correction, so only pipe factory as professional factories often use it.	Basically rarely used.

In the drawings, the tangential cemented carbide chaser install four of the same thread form tangential turning tools. The circular cemented carbide chaser is thread-round Cutters installed on Die.

Radial cemented carbide chaser is the most widely used, factory workers engaged Foreman will be frequently used.

Tap or circular die or the cutters itself are ribbed, so the shape of the individual cutting edge appears to be the same. Full week aliquots of each cutter staggered - one each pitch. For cemented carbide chaser, even if the respective cutter balance of the threads on each tooth, or will be shifted by 1/4 pitch.

Therefore, cemented carbide chaser mounted to the die shoe each knife tooth pitch of 1/4 stagger and sequence alignment. Therefore, must be marked on the cemented carbide chaser number 1 to 4. Write the right side of the right-hand thread, left-hand thread, of course is written on the left. If the order is disrupted, the processing thread will be chaos teeth. Daily custody also must put together a group of four to custody.

Cemented carbide chaser cutting part and tap as well as circular die is the same, but because of the chasers is more solid than taps and circular die, so their teeth will be slightly less.

Cemented carbide chaser anterior horn and posterior horn of the same, and the reason is not difficult to understand. But because carbide thread comb knife mounted on the die shoe, so the chip discharge became a problem. Thus, like the gun-shaped tap, in order to allow the chips can be discharged toward the direction of feed and with a rear corner.

Comb knife processing

the die head cemented carbide the chaser processing thread, there will be all kinds of problems.

① Loose or too heavy ram operating machine tools, machining accuracy will deteriorate.

(2) Material by cutting the material, if you want beveled chasers need funding.

③ Processing thread, and if the outer diameter is large, the cutting resistance will become large, and also deterioration of the finished surface. In order to not cutting as much as possible to the bottom of the thread groove, it is necessary to piecemeal outside diameter.

④ Sometimes because chip clogging chasers can not be opened.
