Introduction of Machining
Have a shape as a processing method, all machining process for the production of the most commonly used and most important method. Machining process is a process generated shape, in this process, Drivers device on the workpiece material to be in the form of chip removal. Although in some occasions, the workpiece under no circumstances, the use of mobile equipment to the processing, however, the majority of the machining is not only supporting the workpiece also supporting tools and equipment to complete.
Machining know the process has two aspects. Small group of low-cost production. For casting, forging and machining pressure, every production of a specific shape of the workpiece, even a spare part, almost have to spend the high cost of processing. Welding to rely on the shape of the structure, to a large extent, depend on effective in the form of raw materials. In general, through the use of expensive equipment and without special processing conditions, can be almost any type of raw materials, mechanical processing to convert the raw materials processed into the arbitrary shape of the structure, as long as the external dimensions large enough, it is possible. Because of a production of spare parts, even when the parts and structure of the production batch sizes are suitable for the original casting, Forging or pressure processing to produce, but usually prefer machining.
作為產(chǎn)生形狀的一種加工方法,機(jī)械加工是所有制造過程中最普遍使用的而且是最重要的方法。機(jī)械加工過程是一個(gè)產(chǎn)生形狀的過程,在這過程中,驅(qū)動(dòng)裝置使工件上的一些材料以切屑的形式被去除。盡管在某些場合,工件無承受情況下,使用移動(dòng)式裝備來實(shí)現(xiàn)加工,但大多數(shù)的機(jī)械加工是通過既支承工件又支承刀具的裝備來完成。
機(jī)械加工在知道過程中具備兩方面。小批生產(chǎn)低費(fèi)用。對于鑄造、鍛造和壓力加工,每一個(gè)要生產(chǎn)的具體工件形狀,即使是一個(gè)零件,幾乎都要花費(fèi)高額的加工費(fèi)用??亢附觼懋a(chǎn)生的結(jié)構(gòu)形狀,在很大程度上取決于有效的原材料的形式。一般來說,通過利用貴重設(shè)備而又無需特種加工條件下,幾乎可以以任何種類原材料開始,借助機(jī)械加工把原材料加工成任意所需要的結(jié)構(gòu)形狀,只要外部尺寸足夠大,那都是可能的。因此對于生產(chǎn)一個(gè)零件,甚至當(dāng)零件結(jié)構(gòu)及要生產(chǎn)的批量大小上按原來都適于用鑄造、鍛造或者壓力加工來生產(chǎn)的,但通常寧可選擇機(jī)械加工。
