精密零部件的表面處理工藝
精密零部件在實(shí)際的工作中對(duì)強(qiáng)度和韌性要求比較高，它的工作性能與使用壽命與其表面性能有著莫大的聯(lián)系，而表面性能的提升，是無(wú)法單純的依靠材料做到的，也是非常不經(jīng)濟(jì)的做法，但實(shí)際加工中卻必須使其性能達(dá)到標(biāo)準(zhǔn)，這時(shí)候就需要用到表面處理技術(shù)了，這往往能達(dá)到事半功倍的效果，近年來這項(xiàng)技術(shù)也得到了飛速的發(fā)展。在模具表面處理優(yōu)先域模具拋光技術(shù)是非常重要的環(huán)節(jié)，也是工件加工處理過程中的重要工藝。精密零部件的表面處理工藝在加工過程中是非常重要的，那么精密零部件的表面處理工藝有哪些呢？
值得提醒的是，精密零部件的模具表面拋光處理工作，不僅僅只收到工藝工序和拋光設(shè)備的影響，同時(shí)還會(huì)受到零件材料鏡面度的影響，這一點(diǎn)在現(xiàn)在的加工中并沒有得到足夠的重視，這也是說明，拋光本身就受到材料的影響。雖然現(xiàn)在提高精密零件表面性能的加工技術(shù)不斷的革新升級(jí)，但是在精密零部件加工中應(yīng)用的比較多的還是主要為硬化膜沉積，和滲氮，滲碳技術(shù)。

The surface treatment technology of precision parts and components requires high strength and toughness in actual work, and its working performance and service life are greatly related to its surface performance, while the surface performance is improved It is not possible to rely solely on materials, and it is also a very uneconomic practice, but in actual processing it is necessary to make its performance up to standard. At this point, surface treatment technology is needed, which can often achieve twice the result with half the effort The technology has also developed rapidly in recent years. In the field of mold surface treatment, mold polishing technology is a very important link, but also an important process of workpiece processing. The surface treatment technology of precision parts is very important in the process of machining, so what are the surface treatment technology of precision parts? It is worth reminding that the surface polishing of precision parts is not only affected by the process and polishing equipment, but also by the specular surface of the parts This point in the current processing has not been enough attention, which is to say, polishing itself is affected by the material. Although the machining technology to improve the surface performance of precision parts is constantly upgraded, but the most widely used in precision parts processing is mainly hardening film deposition, and nitriding, carburizing technology. Because nitriding technology can achieve a very high level of surface properties, and nitriding technology and precision parts of the steel quenching process has a very high consistency, and nitriding temperature is very low, after the nitriding treatment, no drastic cooling process is required, so the deformation of the precision parts will be very small Therefore, nitriding technology is one of the earliest technologies used to enhance the surface properties of precision parts, and is also the most widely used at present
