Carbide Application in Cutting

The emergence of cemented carbide has improved the performance of cutting tools, especially its high hardness and high wear resistance, which can be used by different industries, especially in three major machining fields such as aerospace, automobile industry, and mold manufacturing.

  1. The application of cemented carbide cutting tools in the aerospace field.

   Stainless steel, superalloy, and magnesium-aluminum memory titanium alloy are the main materials used in aerospace. The processing of superalloy and titanium alloy materials used in one of the engines has higher requirements on cutting tools.

Superalloys and titanium alloys maintain high toughness and low thermal conductivity at high temperatures above 540 degrees Celsius, and are called heat-resistant superalloys. These heat-loving super alloys can work for a long time in high temperature oxidizing atmosphere or gas conditions, and improve engine life. Due to the composition and microstructure characteristics of heat-resistant superalloy, its cutting performance is very poor.

The cutting performance of heat-resistant superalloy is very poor, mainly due to the characteristics of high deformation resistance, large work hardening and high processing temperature. For the processing of heat-resistant superalloy, from the perspective of technology and machinability, ceramics and cemented carbide are used. Ideal.

  2. The application of carbide cutting tools in the automotive industry.

    Cast iron has the characteristics of hardness and high compressive strength, and can be cast into complex shapes, and has been used for engine cases and other major parts in the transportation industry. Among them, the comprehensive properties of ductile iron, such as strength and quality, are better than those of gray cast iron, and are widely used in auto parts materials.

Like other low-strength and low-density materials, ductile iron has the characteristics of being difficult to machine. With the increase of pearlite content, the wear resistance is better and the machinability is worse. The porosity of ductile iron leads to continuous cutting and reduces the life of cutting tools.

  3. The application of cemented carbide cutting tools in the field of mold manufacturing.

Mold manufacturing mainly includes automobile manufacturing molds, home appliance molds, building materials molds, electronic communication product molds, etc. The performance characteristics of molds are high hardness, high toughness, high wear resistance, corrosion resistance, and smooth surface.

The performance of the mold material is continuously improved, and the life of the mold is continuously extended. In order to meet the mold material requirements, it is necessary to add alloying elements and control the material organization. These changes have brought difficulties to the cutting of mold materials, such as increased cutting resistance and reduced free-cutting components. Therefore, the cutting tool is required to have cutting properties such as refractory and anti-sticking properties.

The most used cutting tool in the mold manufacturing industry is a carbide milling cutter, which uses a coated carbide tool with high heat resistance, wear resistance and chemical stability!

The existence of cemented carbide materials has also opened up a new field of industry. The advantageous properties of materials make cemented carbide widely used as cutting tools in machining. The development and research of the industry have achieved many large and small enterprises.
