Earlier, we introduced to you where the main advantages of precision parts processing are reflected. Today https://cncmachining.wiki/ will introduce some methods to improve the efficiency of precision parts processing:
In the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing appearance, and difficulty in chip removal will occur. This has seriously affected the quality, production cycle and processing cost of precision parts of such materials.
The processing of non-standard equipment parts requires super-lubricated processing appearance and high processing accuracy, which requires the knife to have a high standard life. Whether the tools of CNC precision processing plants are worn or not will be based on whether the processing surface quality is reduced or not. The standard life of diamond tools is very high, and the tool wear is very slow during high-speed cutting. Therefore, the cutting speed is not restricted by the tool life during ultra-precision cutting, which is different from the general cutting rules.
The cutting speed selected for non-standard equipment parts processing practice is often selected according to the dynamic characteristics of the ultra-precision machine tool used and the dynamic characteristics of the cutting system, that is, the speed with the smallest vibration is selected, because the surface roughness is the smallest and the processing quality is at this speed. The highest, to obtain high-quality non-standard machining appearance is the primary question for non-standard equipment parts processing. Good quality, especially good dynamic characteristics, ultra-precision machine tools with low vibration can use high cutting speeds and increase processing power.
The selection of processing parameters of non-standard equipment parts mainly includes the selection of cutting tool viewpoint, the selection of cutting speed, the selection of cutting depth and feed speed, etc. From past experience, we know that if you choose a larger rake angle when processing plastic materials The tool can effectively inhibit the formation of built-up edge. This is when the rake angle of the tool increases, the cutting force decreases, the cutting deformation is small, and the contact length between the tool and the chip becomes shorter, which reduces the basis for the formation of built-up edge.
