Tooth blade bows on the hardness and wear resistance-blade
Feb 16, 2017

Professional tooth blade for sharpening a pencil's machine knives. Most mechanical parts are made of carbon and alloy structural steel, turning this kind of material, form a ribbon cutting.

High hardness and wear resistance

Hardness is a basic characteristics of a toothed blade material. Tooth blade to cut chips from the workpiece, the hardness must be larger than the hardness of workpiece material. Metal toothed blade used by chip's cutting edge hardness, generally more than 60hrc. Resistance to wear is a material's ability to resist wear. Generally, toothed blade the higher the hardness of the material. Its wear resistance is better. The higher the hardness of the hard spots in the Organization, the greater the number of particles smaller and more evenly distributed, you better wear resistance. Abrasion resistance and chemical composition of materials, strength, microstructure and friction and temperature. Formula wear resistance of materials that are available in an WR;we=kico.5E-0.8h1.43, high hardness, wear resistance, the better.

Sufficient strength and toughness

To make tooth blades take a lot of pressure, as well as cutting process often work under conditions of shock and vibration, without chipping and breaking, machinery blade must have sufficient strength and toughness of the material.

High heat resistance

Heat resistance is the main symbol of measuring tooth blade cutting performance. It refers to the tooth blade hardness of materials in high temperature conditions I agreed, wear resistance, strength and toughness properties. Toothed blade material should have in high temperature oxidation resistance ability as well as good resistance combined with the ability to proliferation-resistant, namely Dan Wei art materials should have a good chemical stability.

Good Thermo-physical properties and thermal shock properties

Toothed blade material thermal conductivity, the better, cutting the heat more easily from the cutting zone, helps to reduce the temperature.
