在现代机械制造業中,由於對另件的精度及表面光潔度要求越来越高,所以機械加工的方法亦越來越精密。精密加工的方法不外乎精細磨削、研磨、砥磨、超級精密加工、及拋光等,其中最簡便而使用廣泛的是精細磨削和研磨。精細磨削在一般情况下,只能達到▽▽▽9～▽▽▽▽10的光潔度。通常只能到▽▽▽9,如果要求達到更高的光潔渡,就必須使砂輪横向進刀接近於零,而增加台面縱向往復次数;這樣生產效率就很低。研磨是利用微細磨料在有潤滑油的條件下所作
In the modern machinery manufacturing industry, due to the accuracy and surface finish of the other parts are increasingly demanding, so the machining method is also more sophisticated. Precision machining is nothing more than fine grinding, grinding, grinding grinding, super precision machining, and polishing, the most simple and widely used is the fine grinding and grinding. Fine grinding in general, can only reach ▽ ▽ ▽ 9 ~ ▽ ▽ ▽ ▽ 10 finish. Usually only to ▽ ▽ ▽ 9, if required to achieve a higher smooth transition, you must make the wheel horizontal infeed close to zero, and increase the vertical reciprocating table; This production efficiency is very low. Grinding is the use of fine abrasive in the presence of oil conditions
