What are the parts for CNC machining?
March 12, 2022
1. The most suitable for multi-type small and medium-sized parts. With the gradual decline in the cost of manufacturing CNC machine tools, now whether domestic or foreign, the processing of large quantities of parts has also emerged. When processing very small batches and single pieces of production, it is optional to shorten the debugging time of the program and the preparation time of the tool.
2. Parts requiring high accuracy. The CNC machine tool has good rigidity, high manufacturing precision, precise tool setting, and easy size compensation, so parts with high dimensional accuracy can be machined.
3. Parts with small surface roughness. In the case of a fixed workpiece and tool material, finishing allowance and tool angle, the surface roughness depends on the cutting speed and the feed rate. Ordinary machine tool is a constant speed, the different diameters of different cutting speeds, such as CNC lathes with constant line speed cutting function, car end surface, different diameters and outer circles can use the same linear speed, to ensure that the surface roughness value is small and consistent. When processing surfaces with different surface roughness, small feedrates are used for surfaces with small roughness, large feedrates are used for surfaces with large roughness, and variability is very good, which is difficult to achieve on ordinary machine tools.
4. Parts with complex contour shapes. Any plane curve can be approximated by a straight line or an arc. The CNC machine tool has a circular interpolation function and can process various complicated contour parts.
