Between suitable spare parts coordinating a relation is to use interference or clearance value to come denotive. In clearance fit, if of the spare parts cooperate the surface coarse, can make cooperate wear away very quickly and increase cooperate clearance, the change cooperates property, reduce cooperate precision; Had been in be filled with in cooperating, if of the spare parts cooperate the surface coarse, the protruding peak that the surface cooperates after be being assembled is squeezed to make the same score, cooperate an effective interference between to reduce, reduce cooperate a join intensity, affect assorted reliability. Because this pair has the face that cooperates a requirement, must the exterior surface roughness with lesser demarcate joins numerical value. The exterior quality of the spare parts still has the effect of other side to the performance characteristics of the spare parts. For example, to hydraulic pressure crock and pilot valve, bigger exterior surface roughness is worth meeting influence sealing; To the slip spare parts when the job, appropriate exterior surface roughness is worth the flexibility that can increase motion, decrease give out heat and power loss; Because stress distributings afresh and the spare parts that the leftover stress of layer of spare parts surface can make had been machined is out of shape, affect its dimension and appearance precision to wait thereby. Anyhow, improve treatment surface quality, it is very important to assuring the performance characteristics of the spare parts, service life that improves a spare parts. CNC MillingCNC Machining
