Formed carbide milling cutters are widely used because of their small shape tolerances. Since the insert cannot be replaced directly, most milling cutters are scrapped after the insert collapses, which greatly increases the processing cost. Now we will analyze the reasons for the wear of carbide cutting tools.

Proper surface treatment can improve tool life, reduce processing cycle time and improve surface quality. In the process of machining, we need to choose the right coating according to the processing needs. Every characteristic of the coating plays a very important role.

Due to the high hardness of Cemented carbide, the abrasive particles of ordinary grinding wheel are easy to be passivated, and the intense friction causes local high temperature on the blade surface, forming additional heating stress, which is easy to cause hot deformation and hot crack, and directly affects the service life and processing quality of the tool. Through processing practice, our company summed up the effective measures to prevent or reduce the grinding crack

There are two types of cutting in the machine factory, which are called "rough cutting" and "finish cutting". After "rough cutting", the workpiece is very close to the required shape and size, but there is still enough metal margin on the processed surface for finishing, so that the surface of the workpiece is smooth and the size is accurate.

Each characteristic of the coating plays an important role in determining which coating is most beneficial to the cutting process.This article will describe some common properties of tool coatings to help us choose the appropriate coating for the tool.

cutting tool wear and durability are related to the efficiency, quality and cost of cutting. In this paper, the causes of abrasive wear, cold welding wear, diffusion wear, oxidation wear and thermoelectric wear are analyzed.
