The common wear types of precision parts processing mainly include running wear, hard particle wear, surface fatigue wear, thermal wear, phase change wear, and fluid power wear.

Running wear is the wear of machinery under normal load, speed and lubrication conditions. This wear generally develops slowly and has little effect on the quality of processing in the short term.

Hard particle wear is due to the abrasive particles dropped by the parts or the hard particles that enter the machine tool by the outside world. They are mixed with the processing area and are mechanically cut or grinded, causing damage to parts, which has a serious impact on the quality of processing.

The surface fatigue wear of the precision parts processing plant is a small crack or a dot -shaped pit pit under the action of mechanical transition loads, causing damage to parts. This type of wear is usually closely related to factors such as pressure, load characteristics, parts materials, and dimensions.

Thermal wear is the heat of the parts during the friction process to the parts, so that the parts can be softened and softened, burning and wrinkles. This type of wear usually occurs in high -speed and high -pressure sliding frictions. The destruction is relatively large and accompanied by accident wear.

Corrosion wear is a chemical effect, that is, chemical corrosion causes wear. When the surface of the part is in contact with acid, alkali, salt liquid or harmful gases, it will be eroded by chemical erosion, or the parts of the parts and oxygen to generate hard and crispy metal oxides that are easy to fall off and wear the parts to wear.

Performance wear is that parts work at high temperatures for a long time. The metal tissue of the parts surface of the parts is hot and large, and the crystal world is oxidized, which produces a small gap, which reduces the fragility and abrasion resistance of the parts, which causes parts to wear.
