Generally speaking, cnc precision machining uses a milling cutter with a large diameter, and the rotation speed is as high as possible, but the machine tool cannot be shaken. The rough milling has a margin of 0.3-0.5mm and then the relevant finishing is performed, can it reach the predetermined accuracy Generally, it depends on whether the linear speed of the milling cutter is enough, and whether the blade is sharp enough.

At this time, a milling cutter with a large diameter is required to operate. This is to easily achieve high linear speed. It is not effective to increase the speed without increasing the diameter of the milling cutter. In addition, a sufficient amount of cutting fluid should be added during fine milling.

What is the surface roughness of cnc precision machining? The general machine tool is basically about 3.2, and the high-speed machine can basically achieve a smoothness of 1.6. Pay attention to the tools and cutting parameters used during processing.
