Advantages Of CNC Machine Tools And General Machine Tools

2019-12-03

Ordinary machine tools are of constant speed, and the cutting speed is different with different diameter. For example, large-scale computer gongs machining CNC lathe has the function of constant linear speed cutting. When turning the end face and the outer circle of different diameter, the same linear speed can be used to ensure that the surface roughness value is both small and consistent.

High precision parts. It has the advantages of good rigidity, high manufacturing accuracy, accurate tool setting and convenient dimension compensation, so it can process parts with high dimension accuracy requirements.

Most suitable for many kinds of small and medium batch parts. When processing small batch and single piece production, it is also optional to shorten the debugging time of the program and the preparation time of the tooling. With the gradual decline of the manufacturing cost of CNC machine tools, the situation of processing large quantities of parts has emerged, both at home and abroad.

Parts with complex contour. Any plane curve can be approximated by a straight line or an arc. The CNC machine tool has the function of arc interpolation, and can process various parts with complex contour.

Parts with small surface roughness value. When machining different surface roughness with large computer gong, the surface with small roughness adopts small feed speed, and the surface with large roughness adopts larger feed speed, which has good variability, which is difficult to achieve in ordinary machine tools. The surface roughness depends on the cutting speed and feed speed when the material, finishing allowance and tool angle of workpiece and tool are fixed.
