As a main material for high-speed cutting, cutting tool materials are constantly developing, and this situation will not change much in the future. So how much do you know about the materials of cutting tools?
Cutting tool material refers to the material used to manufacture cutting tools for machining. The properties that the tool material must have are hardness (HRC60 or more), strength and toughness, thermal hardness, thermal strength, wear resistance and manufacturability.
Commonly used cutting tool materials include carbon tool steel, alloy tool steel, high-speed steel, cemented carbide, alumina-based ceramics and silica-based ceramics, synthetic diamonds, cubic boron nitride, etc.
A cutting tool for processing soft materials, characterized in that: on the surface of a base material composed of a hard material, a convex portion with a cutter ridge line is formed protruding upward, and at the same time, it is in contact with at least the convex portion A pressing part is formed adjacent to the front side in the cutting direction of the material to be cut and protruding upward, and the height of the pressing part is lower than the height of the above-mentioned convex part.
People use cutting tools to process and produce metal, plastic, rubber, wood and other parts. Cutting tool materials can be divided into two major categories.
The first is the widely used tool steel
The second is cutting alloy
According to the different chemical composition, performance and application range of tool steel, it can be divided into a series of different grades, such as load and heat resistance grade. It can keep its performance unchanged under high temperature conditions.
At present, it can be seen in the market that with the introduction of CNC machine tools and various special-purpose machine tools, as cutting processing automation and energy saving tools, the reliability of tool materials has become an important condition that should be possessed. The characteristics of cutting tools are that they require resistance Wearability and durability; generally speaking, reliability refers to durability. To meet such requirements, it is necessary to use highly versatile tool materials that do not damage wear resistance and increase toughness.
