波胆历史 工艺可分为铸造、锻造、冲压、焊接、机械加工、装配等工艺。机械制造工艺一般是指零件的机械加工工艺和机器装配工艺的总和，其他工艺称为运输、储存、供电、设备维护等辅助工艺。工艺由一个或多个顺序排列的过程组成，一个过程由多个步骤组成。
车削（立车、卧车）：车削是从工件上切除金属的加工。在工件旋转的同时，刀具切入工件或沿着工件车削；
铣削（立铣、卧铣）：铣削是使用旋转刀具切除金属的加工，主要用于加工槽和外形直线面，也可以两轴或者三轴联动加工弧面；
镗孔：镗孔是把工件上已钻出或铸出的孔加以扩大或作进一步加工的加工方法。主要用于加工工件外形较大、直径较大、精度较高的孔加工。
刨削：刨削主要特性是加工外形直线面，一般情况下表面粗糙度没有铣床高；
插削：插削实际上是立式刨床，它的刀具是上下运动的，非常适合非完整圆弧加工，主要用于切削某些类型的齿轮；
磨削（平面磨、外圆磨、内孔磨、工具磨等）：磨削是使用磨削轮来切除金属的加工方法，加工后的工件尺寸准确、表面光洁。主要用于对经过热处理的工件进行精加工，使其达到准确的尺寸。
钻削：钻削是使用旋转钻头在实心金属工件上进行钻孔加工；钻孔时，工件定位夹紧、固定不动；钻头除旋转外还要沿自身轴线作进给运动。
The machining process in Dalian can be divided into casting, forging, stamping, welding, mechanical processing, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines, while other processes are called auxiliary processes such as transportation, storage, power supply, and equipment maintenance. Craftsmanship consists of one or more sequentially arranged processes, with each process consisting of multiple steps.
Turning (vertical lathe, horizontal lathe): Turning is the process of cutting metal from a workpiece. While the workpiece rotates, the tool cuts into or turns along the workpiece;
Milling (vertical milling, horizontal milling): Milling is the process of cutting metal using a rotating tool, mainly used for machining grooves and straight surfaces, and can also be used for two or three axis linkage machining of curved surfaces
Boring: Boring is a machining method that enlarges or further processes holes that have already been drilled or cast on a workpiece. Mainly used for machining holes with larger shapes, larger diameters, and higher precision of workpieces.
Planing: Planing is mainly characterized by processing straight surfaces, and in general, the surface roughness is not as high as that of milling machines;
Insertion cutting: Insertion cutting is actually a vertical planer, and its cutting tools move up and down, which is very suitable for incomplete arc machining and mainly used for cutting certain types of gears;
Grinding (flat grinding, external cylindrical grinding, internal hole grinding, tool grinding, etc.): Grinding is a machining method that uses grinding wheels to remove metal, resulting in accurate dimensions and smooth surfaces of the processed workpiece. Mainly used for precision machining of heat-treated workpieces to achieve accurate dimensions.
Drilling: Drilling is the use of a rotary drill bit to drill holes on solid metal workpieces; During drilling, the workpiece is positioned, clamped, and fixed in place; In addition to rotation, the drill bit also needs to perform feed motion along its own axis.
