　　Non-standard parts processing manufacturer: How to prevent wear in precision parts processing

　　Common types of wear in precision parts processing factories mainly include running-in wear, hard particle wear, surface fatigue wear, thermal wear, phase change wear, and fluid dynamic wear. Running-in wear occurs under normal load, speed, and lubrication conditions, generally developing slowly and having little impact on processing quality in the short term.

       Hard particle wear is caused by abrasive particles falling from the part itself or hard particles entering the machine tool from the outside, mixing into the processing area, and being subjected to mechanical cutting or grinding, resulting in damage to the parts and severely affecting processing quality.

　　Surface fatigue wear in precision parts processing factories occurs under alternating loads, causing the machine to produce tiny cracks or pits, leading to damage to the parts. This type of wear is usually closely related to factors such as pressure, load characteristics, machine part materials, and size.

　　Thermal wear is the heat generated during friction acting on the parts, leading to phenomena such as tempering softening and scorching wrinkling of the parts. This type of wear usually occurs in high-speed, high-pressure sliding friction, is destructive, and is accompanied by unexpected wear.

　　Erosion is a chemical action, that is, chemical erosion causes erosion. When the surface of the parts comes into contact with acidic, alkaline, saline liquids, or harmful gases, it will be subjected to chemical erosion, or the surface of the parts combines with oxygen to form hard, brittle, easily detachable metal oxides, causing wear.

　　Phase change wear refers to wear caused by long-term operation of parts at high temperatures. When the metal structure grains on the surface of the parts are heated and enlarged, the grain boundaries are oxidized, creating tiny gaps that make the parts brittle and reduce wear resistance.
