Precision machining is t北飛he process of changin筆從g the size or performance o見話f a workpiece through司靜 a machine. According t路鄉o the temperature state of the workp為國iece. Machining processes that a在月re higher or lower than木制 normal temperature can cause c體錢hemical changes in the workp南通iece are called thermal processing. Col近船d processing can be divi習妹ded according to different mecha著書nical processing metho兵雨ds. Used for cutting and pr笑市essure processing. T行機hermal processing is often美哥 used for heat treatment, calcinati明鐵on, casting and welding. It is d長能ivided into cold working and hot wo嗎家rking. Generally, mechanical 白謝processing is performed at r友間oom temperature without causing ch唱睡emical changes to the workpiece, 校相which is called cold process明友ing. Generally speaking. The production個算 process of precision machining i林銀ncludes the transportation and sto雨廠rage of raw materials, produc笑一tion preparation, rough machinin來訊g, parts processing a電們nd heat treatment, product assemb科白ly and debugging, painting and packagi廠月ng. The production process of pre體西cision machining refers to 劇樹the whole process of manufactur視做ing products from raw m近通aterials (or semi-finis雨白hed products). Precision machin好得ing
