The Material Of Domestic Alloy Planer Blades Is Constantly Updated In The Manufacturing Industry.
- Jul 21, 2018 -

Carbide material is still a major member of tool materials, and it is also one of the tool materials developed by tool manufacturers in various countries. The breadth and depth of its application have made significant progress. The development of fine-grained and ultra-fine particle cemented carbide materials It is the development direction to further improve the reliability of tool use.

     

Nano-coating, gradient structure coating and coating of new structure and material are the development direction to improve the performance of the tool. The application of physical coating will continue to increase, pure ceramic, cermet, silicon nitride ceramic.

 

The use of new material tools has greatly improved the cutting efficiency. The high cobalt high vanadium high performance high speed steel tool can be 1.5 to 3 times more durable than ordinary high speed steel. The strength of powder metallurgy high-speed steel can be increased by 20% to 30%, the toughness is increased by 1.5 to 2 times, and the reliability is obviously higher than that of ordinary high-speed steel. The small drill bit made of powder metallurgy high-speed steel has been widely used in foreign processing centers. Taps and milling cutters, etc., are still rarely used in China.

 

In recent years, foreign countries have developed a variety of new components, new grades of cemented carbide, developed high-strength and high-toughness 0.5 ~ 1μm ultra-fine particles of cemented carbide, developed a variety of new coatings of hard alloys, making hard alloys The cutting performance has been significantly improved, replacing some of the more complex tools that were previously only possible with high speed steel.

 

Ultra-hard material tools such as ceramics, cubic boron nitride and polycrystalline diamond are widely used in foreign countries. The cutting speed can be several times higher than that of hard alloys, which greatly improves the processing efficiency. In Germany, about 70% of castings are processed with ceramic tools. The annual consumption of Japanese ceramic knives has accounted for 8% to 10% of the total number of tools, while China's superhard material tools are still used very little.
