The Factors Affecting Surface Roughness Of Large-Scale CNC Lathe

The geometric characteristics of the surface processed by large-scale CNC lathes include surface roughness, waviness and machining texture. The advantages of large-scale CNC lathe machining and the five factors that improve the machining efficiency of CNC lathes are what we must know. However, the surface roughness of large-scale CNC lathes is the basic unit of surface geometric characteristics, which affects the surface roughness of large-scale CNC lathes. Do you know any? PTJ will do a simple analysis for everyone.

The Factors Affecting Surface Roughness Of Large-Scale CNC Lathe

1. Factors affecting the surface roughness of large-scale CNC lathes: geometric factors

From the geometric point of view of surface roughness, the shape and geometric angle of the tool, especially the radius of the tip arc, the main deflection angle, the secondary deflection angle, and the amount of feed in the cutting amount, have a greater impact on the surface roughness.

2. The second factor affecting the surface roughness of large-scale CNC lathes: physical factors

Considering the physical essence of the machining process of large-scale CNC lathes, the cutting edge fillet of the tool and the subsequent extrusion and friction cause plastic deformation of the metal material, which seriously deteriorates the surface roughness. When machining plastic materials on a large-scale CNC lathe to form band-shaped chips, built-up edges with high hardness are likely to be formed on the rake face. It can replace the rake face and cutting edge for cutting, so that the geometrical angle of the tool and the amount of back-cutting can be changed. The contour of the built-up edge is very irregular, so that the depth and width of the tool marks on the surface of the workpiece are constantly changing. Some built-up tumors are embedded in the surface of the workpiece, which increases the surface roughness. Vibration occurs during cutting, which increases the surface roughness parameter value of the workpiece.

3. Three factors affecting the surface roughness of large-scale CNC lathes: machining process factors

Considering its influence on the surface roughness of the processed workpiece from the perspective of large-scale CNC lathe machining technology, there are mainly factors related to cutting tools, factors related to workpiece material, and factors related to CNC machining conditions.

The surface roughness of large-scale CNC lathes is mainly affected by geometric factors, physical factors and machining technology factors.
