The cemented carbide cutting dies suitable for machining in the cast iron, heat-resistant alloy steel, hardened steel, hard material, such as workpiece outer thread is also suitable for use in the relatively soft material of aluminum alloy or the like on the workpiece machining external thread, particularly aluminum alloy material of the workpiece on the processing the external thread, the processing efficiency, the threaded surface roughness, and thread size stability are die of other materials can not achieve. The wear resistance of cemented carbide cutting dies are cutting dies can not be compared to the other materials.

The cemented carbide cutting dies manufacturing a much more than ordinary dies and high-speed steel teeth difficult, mainly when in processing cutting dies threaded, there are still some processing process issues. Specifications cemented carbide cutting dies casing Usually back manufacturing, steel blade with carbide materials. Its structure is the edge back less than ordinary cutting dies of the same specifications, the chip holes are drilled in the oval (see figure), greatly increasing the chip space, conducive to cutting. Ordinary cutting dies and high-speed steel teeth, cemented carbide cutting dies use of the range of small, suitable for processing large quantities of the workpiece. Cemented carbide cutting dies does not have the versatility.

Depending on the material to be processed, you should choose a different cemented carbide cutting dies materials and different cutting parameters. When machining cast iron, the rake angle desirable 3 ° ~ 5 °, the posterior horn desirable 2 ° to 4 °; processing heat-resistant alloy steel, hardened steel and other hard materials, from 0 ° to 2 ° rake angle desirable, the posterior horn desirable 2 ° ~~ 3 °; machining aluminum and other softer material, the anterior horn desirable 10 ° ~ 15 °, 4 ° to 8 ° posterior horn desirable.

According to the size of the workpiece thread diameter and pitch, when machining cast iron, the cutting speed to take (16 to 30) m / min; machining of hard materials and hardened steel, take (0.5-5.0) m / min cutting speed; machining aluminum Cutting speed taken (40 ~ 60) m / min.

The cemented carbide the cutting dies edge on the tip arc greater than alloy steel dies and high-speed steel plate teeth, high-speed cutting with compression, aluminum alloy processing thread roughness far below the alloy steel dies and high-speed steel plate teeth processing effect.
