Milling stainless steel except for end mills and some end mills and carbide milling cutter materials, all other types of milling cutters are made of high-speed steel, especially tungsten molybdenum and high-vanadium high-speed steel have good results, and the tool durability is comparable W18Cr4V is 1 to 2 times higher. The cemented carbide grades suitable for manufacturing stainless steel milling cutters are YG8, YW2,813,798, YS2T, YS30, YS25, etc.

Cemented carbide milling cutters are mainly divided into: solid carbide milling cutters | cemented carbide straight shank milling cutters | cemented carbide saw blade milling cutters | cemented carbide spiral milling cutters | cemented carbide machine reamer milling cutters | Alloy end mills|Cemented carbide ball end mills. Carbide milling cutters are usually used in CNC machining centers and CNC engraving machines. It can also be loaded on a traditional milling machine to process some hard and uncomplicated heat-treated materials.

CNC machining tools must adapt to the characteristics of high-speed, high-efficiency, and high degree of automation of CNC machine tools. Generally, they should include general-purpose tools, general-purpose connection tool holders and a small number of special-purpose tool holders. The tool holder must be connected to the tool and mounted on the power head of the machine tool, so it has gradually been standardized and serialized. There are many ways to classify CNC tools. 1. According to the tool structure, it can be divided into: ①Integral type; ②Inlaid type, using welding or machine clamp connection......

Cemented carbide is mainly composed of high-hardness, refractory metal carbides (WC, TiC) micron powders, and cobalt (Co), nickel (Ni), and molybdenum (Mo) as binders. It can be used in a vacuum furnace or hydrogen Powder metallurgy products sintered in a reduction furnace. The carbides, nitrides, borides, etc. of Group IVB, VB, and VIB metals are collectively referred to as hard alloys due to their extremely high hardness and melting point. The following focuses on carbides to illustrate the structure, characteristics and applications of hard gold.

Although we always hope to have both high hardness to ensure the wear resistance of the tool, and high toughness to prevent the tool from chipping, the current technological development has not found such a superior performance tool material. Can't have both. Therefore, we will choose more suitable tool materials in practice according to the needs: the toughness of the tool material is given priority when roughing: the hardness of the tool material is given priority when finishing.

In order to improve the cutting performance of cemented carbide, more than 80% of cemented carbide tools in industrially developed countries have undergone surface coating treatment. Over the past few decades, double-coated, triple-coated and multi-coated composite blades have been developed at home and abroad, and some of them have even reached dozens of layers or hundreds of layers. Cemented carbide coating technology can generally be divided into two categories: chemical vapor deposition (CVD) technology and physical vapor deposition (PVD) technology.
