What are the types of carbide brazing inserts currently used in China?

       

The cemented carbide turning tool is welded with a cemented carbide inserts and a carbon steel material inserts, which has high hardness, wear resistance and heat resistance. The cemented carbide inserts is made of high wear resistance and high heat resistance WC (Tungsten carbide), TiC (titanium carbide), TaC (tantalum carbide) and Co (cobalt) powders are sintered at high temperature. Now let's analyze which types of carbide brazing inserts currently used in my country are divided into?

 

Tungsten carbide inserts

 

1) Tungsten Cobalt (WC+Co) inserts

 

Tungsten and cobalt inserts, the domestic nominal YG category, the corresponding international nominal category K, this type of alloy inserts is used to process ferrous metals, non-ferrous metals and non-metallic materials that produce short chips, such as cast iron, aluminum alloy, copper alloy, and plastic , Hard Bakelite, etc. Commonly used grades are YG3, YG6, YG8, etc.,

 

2) Tungsten-titanium-cobalt (WC+TiC+Co) inserts

 

Tungsten-titanium-cobalt inserts, the domestic nominal YT type, and the corresponding international nominal P-type alloy inserts are used to process metal materials that produce long chips, such as steel, cast steel, malleable cast iron, stainless steel, heat-resistant steel, etc. Commonly used grades are YT5, YT15, YT30, etc.

 

3) Tungsten-titanium-tantalum-cobalt (WC+TiC+TaC+co) inserts

 

Tungsten-titanium-tantalum-cobalt inserts, national standard YW category, corresponding to the international nominal M category, this kind of alloy inserts are used to process ferrous or non-ferrous metals that produce long and short chips, such as steel, cast steel, austenitic stainless steel, resistant Hot steel, malleable cast iron, alloy cast iron, etc.

 

3. Diamond (PCD) turning tools

 

Diamond turning tools mainly process copper, aluminum, zinc, alloys and plastics, rubber, bakelite and other non-ferrous and non-metal materials that require high finish. Diamond turning tools have high finish and high wear resistance.

 

4. Cubic Boron Nitride (PCBN)

 

Cubic boron nitride turning tools mainly process ferrous metals with high hardness, such as hardened steel and iron-based powder metallurgy. This turning tool is characterized by high hardness and high wear resistance.

 

5. CNC turning tool (indexable turning tool)

 

CNC turning tools are mainly used for turning tools on CNC machine tools. It is a turning tool that is clamped by CNC inserts and tool holders through screws and other devices. The biggest feature of this type of turning tool is the interchangeability of the inserts.
