Cemented carbide milling cutters are mainly made of cemented carbide round bars

Cemented carbide milling cutters are mainly made of cemented carbide round bars, which are mainly used in CNC tool grinders as processing equipment, and gold steel grinding wheels as processing tools. MSK Tools introduces cemented carbide milling cutters that are made by computer or G code modification of the processing road. This processing method has the advantages of high efficiency, high precision, and good batch production consistency. The disadvantage is that most equipment is Generally, the price of imported products is more than 150 thousand dollar.
 
There is also processed by general equipment, which is divided into groove grinding machine processing spiral groove, end gear processing end tooth and end, and edge cleaning machine (peripheral gear machine) processing peripheral teeth. This kind of product needs to be separated by various sections. The labor cost for processing is very high, and the quality of mass-produced products is controlled by the proficiency of the workers themselves in operating the machine, so the accuracy and consistency will be worse.

In addition, the quality of cemented carbide milling cutters is related to the trademark of the selected cemented carbide materials. Generally, the appropriate alloy trademark should be selected according to the processed materials. Generally speaking, the smaller the alloy grains, the better the processing.
 
The main difference between high-speed steel milling cutters and cemented carbide milling cutters is: high-speed steel needs to be processed through heat treatment to increase its hardness, while ordinary steel is soft as long as it does not pass heat treatment.

Milling cutter coating
The coating on the surface of the milling cutter generally has a thickness of about 3 μ. The main purpose is to increase the surface hardness of the milling cutter. Some coatings can also reduce the affinity with the processed material.
 
In general, milling cutters cannot have both durability and hardness, and the emergence of coating skills has solved this situation to a certain extent. For example, the base of the milling cutter is made of raw materials with higher resistance, and the surface is coated with hardness. High coating, so the function of the milling cutter is greatly improved.
