二、高强度不锈钢细长轴的磨削我们加工的OCr17Ni7Al沉淀硬化不锈钢细长轴的尺寸精度和形位精度要求较高,表面光洁度要求达到▽8。在半精车削加工后,还需要进行精磨加工,而磨削加工比车削加工的难度更大,一般具有如下特点: (1) 加工表面容易烧伤; (2) 切屑容易堵塞砂轮; (3) 切屑难于切离,磨粒容易磨纯; (4) 细长工件很容易弯曲变形; (5) 切削表面容易冷作硬化。针对上述难加工因素,我们通过工艺试验,合理地选择砂轮、工件的装夹方法、磨削用量、冷却润滑液
Second, the high strength stainless steel slender shaft grinding Our OCr17Ni7Al precipitation hardened stainless steel slender shaft size and shape accuracy of high precision requirements, surface finish requirements ▽ 8. After the semi-finish turning machining, it is also necessary to finish the grinding. The grinding process is more difficult than the turning process, and generally has the following features: (1) the burnishing surface is easy to burn; (2) the chip is easy to block the grinding wheel; (3) Chip is difficult to cut off, abrasive easy to grind pure; (4) elongated workpiece is easy to bend deformation; (5) cutting surface easy to harden cold. In response to the above difficult processing factors, we pass the process test, a reasonable choice of grinding wheel, workpiece clamping method, the amount of grinding, cooling lubricant
