How can the surface roughness of CNC processed aluminium alloy reach 0.8?
With a large diameter milling cutter head, the speed is as high as possible, but the machine tool can not shock, rough milling reserved 0.3-0.5 mm margin for finishing, can be achieved depends on the milling cutter line speed is not enough, the blade is sharp or not. The purpose of large diameter milling cutter head is to achieve high linear speed easily. It is not good to increase the speed without increasing the diameter of milling cutter head. Shenzhen Yuezhengjia Technology Co., Ltd. can achieve 0.8 roughness in general. In addition, when finishing milling, we need to add enough cutting fluid.
What is the roughness of CNC machined surface?
General machine tools are about 3.2, high-speed machine can reach 1.6 smoothness; attention is to see the tool and cutting parameters used in processing.
Is the smaller the surface roughness value, the finer it is?
1. The profilometer is not the same product as the roughness meter. The main function of the profilometer is to measure the contour shape of the part surface.
For example: Shenzhen Yuezhengjia Technology Co., Ltd. CNC processing of automotive parts groove depth, groove width, chamfer (including chamfer position, chamfer size, angle, etc.), cylindrical surface straightness and other parameters. In short, the profilometer reflects the macroscopic outline of the parts.
2. The function of the roughness meter is to measure the surface quality of the grinding/finishing process of the surface of the parts. Generally speaking, it means that the surface of the precise hardware parts is not polished (the old national standard of roughness is called smoothness). That is to say, the roughness reflects the Micro-condition of the surface of the parts.
