精密零部件的表面处理工艺

精密零部件在实际的工作中对强度和韧性要求比较高,它的工作性能与使用寿命与其表面性能有着莫大的联系,而表面性能的提升,是无法单纯的依靠材料做到的,也是非常不经济的做法,但实际加工中却必须使其性能达到标准,这时候就需要用到表面处理技术了,这往往能达到事半功倍的效果,近年来这项技术也得到了飞速的发展。在模具表面处理领域模具抛光技术是非常重要的环节,也是工件加工处理过程中的重要工艺。精密零部件的表面处理工艺在加工过程中是非常重要的,那么精密零部件的表面处理工艺有哪些呢?

值得提醒的是,精密零部件的模具表面抛光处理工作,不仅仅只收到工艺工序和抛光设备的影响,同时还会受到零件材料镜面度的影响,这一点在现在的加工中并没有得到足够的重视,这也是说明,抛光本身就受到材料的影响。虽然现在提高精密零件表面性能的加工技术不断的革新升级,但是在精密零部件加工中应用的最多的还是主要为硬化膜沉积,和渗氮,渗碳技术。

因为渗氮技术能够获得很高水准的表面性能,而且渗氮技术的工艺跟精密零部件中钢的淬火工艺有着非常高的协调一致性,而且渗氮的温度是非常低的,这样在经过渗氮技术处理后就并不需要激烈的冷却工序,因此精密零部件的变形就会非常小,因而渗氮技术也是在精密零部件加工时用来强化表面性能采用最早的技术之一,也是目前应用最广泛

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
