►Main cause of abrasion

Abrasion of CNC inserts, abrasive wear chips or some tiny hard spots (such as carbides, oxides, etc.) and impurities (such as sand, oxide scale, etc.) on the surface of the workpiece, as well as adhered built-up edge fragments, etc. A type of mechanical wear caused by a grooved surface inscribed on the surface. For high-speed steel tools with low speed and low cutting temperature (such as broaches, dies, taps, etc.), it is the main cause of wear.
Adhesive wear forms fresh surface contact under the action of positive pressure and cutting temperature between the flank of the CNC blade and the surface of the workpiece and the rake surface of the CNC blade and the chip. Adsorption bonding occurs when the contact surfaces reach the interatomic distance. The station node is gradually cut and torn away by the workpiece or the chip, and the surface of the CNC blade produces adhesive wear. Bonded wear is one of the main causes of carbide wear when cutting at moderately low cutting speeds.
Diffusion wear is under high temperature and high pressure, and some chemical elements in the CNC blade material and the workpiece material diffuse each other in the solid state, that is, elements such as Ti, W, Co in the cemented carbide diffuse into the steel, while Fe, C in the workpiece Such elements spread to the CNC blade, resulting in a decrease in the hardness and strength of the blade surface, an increase in brittleness, and aggravation of tool wear. This is diffusion wear, and diffusion wear is one of the main reasons for the wear of cemented carbide tools during cutting at high temperatures (800"900°C).
Generally, the diffusion rate of W and Co is faster than that of Ti and Ta, so the high-temperature cutting performance of YT-type cemented carbide is better than that of YG-type. When the high-speed steel tool is used for phase change wear, when the cutting temperature exceeds its phase transition temperature (550"600°C), the metallographic structure of the CNC insert will change, the hardness will decrease, and the wear will be accelerated. One of the main reasons for the wear of high-speed steel CNC inserts. Chemical wear at a certain temperature, the surrounding media in the cutting area, such as air, cutting fluid, etc., chemically react with the tool material to form some loose and fragile compounds. These compounds are easy to be cut and The workpiece is scratched and taken away, causing wear of the CNC blade.
