In mechanical manufacturing, the whole process of 3312 bearing number details the mechanical products made from raw materials of known as the production process machinery.
Purchase, transportation, storage and preparation of raw materials 1.1. (HS division, blank database)

Manufacturing 1.2 blank (HS division, structure workshop)
1.3 blank after machining, heat treatment and surface treatment and become parts (processing workshop, heat treatment, etc.)
The assembly of 1.4 parts (assembly shop)
Quality inspection of 3312 bearing number details 1.5 machine and test test (Technology Department, inspection department, assembly workshop)
Paint and packaging of the 1.6 mechanical (paint factory and packing factory)
Here are some concepts in machining
The 1.1 step: is a (or several) workers in a work place for the completion of a (or several
A) a part of the machining process of parts, it is the basic part of the process. (such as quenching and tempering before and after C630 lathe in circular process, is the two truning process; in the portal frame in the 10 meters above the car stop)
A parts to be processed in order to be multiple processes become finished products.
1.2 station: in some cases, a process, the workpiece to be changing the location and multiple clamping in machining process, so that the processing of different, each position the workpiece in the machine is called a station.
Such as: walking saddle processing on a boring machine top hole and the plane is a station, a boring shaft hole and the end face is a station.
1.3 step: sometimes in a process, also need to cutting tools and cutting parameters of different, different surface processing, in which the same tools, the same cutting parameters, processing the same surface of 3312 bearing number details the part is called a step.
1.4 take the knife: in one step, sometimes due to cut the metal layer is very thick, but not a cut up, need several times after cutting, then each cutting is called a knife.
