How to achieve 0.8 surface roughness of aluminum alloy processed by cnc?

Use a milling cutter with a larger diameter, and the rotation speed should be as high as possible, but the machine tool should not vibrate, and the rough milling should leave 0.3-0.5mm margin before finishing. Whether it can reach it depends on the milling cutter linear speed and whether the blade is sharp or not. . The purpose of the milling cutter head with a larger diameter is to easily achieve high linear speed. It is not good to increase the speed without increasing the diameter of the milling cutter head. In this way, the roughness can reach 0.8 in general. In addition, a sufficient amount of cutting fluid should be added when finishing milling.

  What is the surface roughness of general CNC machining?

   Generally, ordinary machine tools are processed at about 3.2, and high-speed machines can reach a finish of 1.6; pay attention to the tools and cutting parameters used in the processing.

  Is the smaller the surface roughness of the part, the finer it is?

  1. About the profiler and the roughness meter. The profiler is not the same product as the roughness meter. The main function of the profiler is to measure the contour shape of the surface of the part.

   such as: groove depth, groove width, chamfer (including chamfer position, chamfer size, angle, etc.) of grooves in automotive parts, straightness of the cylindrical surface, and other parameters. In short, the profiler reflects the macro outline of the part.

2. The function of the roughness meter is to measure the surface processing quality of the grinding/finishing process of the part surface. In layman's terms, the surface of the part is not polished (the old national standard for roughness is called smoothness), that is, the roughness reflects The microscopic condition of the machined surface of the part.
