Most machine parts made from metal machining are machined and manufactured before they are installed on mechanical equipment. Machining is usually the production process of machine parts before installation. Therefore, the quality and price of mechanical processing to the quality and cost of most equipment machinery parts have great harm. In addition, processing complex, commonly used CNC lathes, CNC blades, fixtures, measuring tools and so on. Their characteristics, characteristics, fineness, production efficiency, etc. It's not the same. Some parts need heat treatment and artificial aging in the process of parts manufacturing. Therefore, in the design process, it is important to consider the machining.

Metal machining or specifications are particularly heavy, high fineness, small specifications, unique application standards, and the total output is particularly large. The manufacture and processing of such unique machine parts usually have a great deal of uniqueness, which should be taken into account when formulating. Whether or not a part can be manufactured is likely to be a key factor in the design.

For the structural design of metal machined parts, the following problems should be paid special attention:

1) Structural design of raw material saving parts.

2) The product structure design reduces the labor of machining and manufacturing.

3) Reduce manual processing or fill the product structure design of production processing.

4) Simplify the shape and rules of the surface to be produced and processed.

5) The product structure design of metal machining is conducive to clamping measurement.

6) Prevent the CNC blade from being at a disadvantage when drilling.

7) Timely treatment of shaft and hole structure (inner and outer layer).
