轴类零件是一种常见的零件类型，其结构为旋转体，长度一般大于直径，在各种机械设备中有广泛地使用，用来支承传动零部件，传递扭矩和承受载荷。轴类零件的加工要遵循一定的规律，可以通过本文了解一下具体的加工步骤和需要注意的一些问题。
轴类零件的主要加工表面是外圆表面以及常见的特形表面，因此应该针对各种精度等级和表面粗糙度要求，选择最合适的加工方法。其基本加工路线可以归纳为四条。
首先是从粗车到半精车，再到精车的加工路线，这也是针对一般常用材料轴类零件针外圆加工，选择的最主要的工艺路线；其次是从粗车到半精车，再到粗磨，最后采用精磨的加工路线，对于黑色金属材料和精度要求较高，表面粗糙度要求较小且需要淬硬的零件，这种加工路线是最好的选择，因为磨削是其最理想的后续加工工序；第三种路线是从粗车到半精车，再到精车，金刚石车，这种加工路线专门用来加工有色金属材料，因为有色金属硬度较小，容易堵塞沙粒间的空隙，采用磨削通常不容易得到所要求的表面粗糙度，必须采用精车和金刚石车工序；最后一种加工路线是从粗车到半精车，再到粗磨，精磨，最后进行光整加工，这种路线对于黑色金属材料经过淬硬，且对精度要求较高，表面粗糙度值要求较低的零件是一种经常会采用的加工路线。
Shaft parts is a common type of parts, its structure for the rotating body, the length is generally greater than the diameter, in a variety of mechanical equipment has a wide range of use, used to support the transmission components, transmission torque and load bearing. Shaft parts processing to follow certain rules, you can learn about the specific processing steps and some of the issues that need attention through this article.
Shaft parts of the main machining surface is the cylindrical surface and common special-shaped surface, so it should be for a variety of accuracy levels and surface roughness requirements, choose the most appropriate processing method. Its basic machining route can be summarised as four.
Firstly, from rough turning to semi-finish turning, and then to fine turning processing route, which is also commonly used for general material shaft parts needle cylindrical machining, the choice of the most important process routes; secondly, from rough turning to semi-finish turning, and then to rough grinding, and finally the use of fine grinding machining routes for ferrous materials and high precision requirements, surface roughness requirements of the smaller and need to be quenched and hardened parts, this machining route is the best choice, because grinding is its most ideal choice, and the surface roughness is the best choice. Because grinding is the most ideal subsequent processing process; the third route is from rough turning to semi-finishing turning, and then to fine turning, diamond turning, this processing route is specially used for processing non-ferrous metal materials, because non-ferrous metal hardness is small, easy to block the gap between the sand particles, the use of grinding is usually not easy to get the required surface roughness, it must be used in the fine turning and diamond turning process; the last kind of processing route is from rough turning to The last machining route is from rough turning to semi-fine turning, then to rough grinding, fine grinding, and finally finishing process, this route for ferrous materials after hardening, and for the higher precision requirements, the surface roughness value of the parts required to lower is a kind of machining routes will often be used.
