Many manufacturers now use precision parts for processing,
which saves a lot of labor and time, but the efficiency is not very good. How can we improve the efficiency in CNC machining ?
The processing of non-standard equipment parts requires super-lubricated machining appearance and high machining accuracy. This requires that the knife has a high standard life,
whether the tool is worn, and it will be based on whether the quality of the machining appearance is reduced. The standard life of diamond tools is very high, and tool wear is very slow during high-speed cutting.
Therefore, in ultra-precision cutting, the cutting speed is not restricted by the tool life, which is different from the general cutting rules.
The cutting speed selected for non-standard equipment parts processing practice is often selected based on the dynamic characteristics of the ultra-precision machine tools and the cutting system, that is, the minimum vibration speed.
At this speed, the surface roughness is the smallest and the CNC machining quality is the highest. Obtaining high-quality non-standard machining appearance is the primary question for non-standard equipment parts processing.
Ultra-precision machine tools with good quality, especially good dynamic characteristics and small vibration, can use high cutting speed and can process power.
The selection of processing parameters of non-standard equipment parts mainly includes the selection of the cutting tool viewpoint, the selection of the cutting speed and the selection of the cutting depth and feed speed.
From the past experience, we know that if you choose a tool with a large rake angle when processing plastic data, you can use the structure of the built-up chippings.
When the rake angle of the tool is increased, the cutting force is reduced, the cutting deformation is small, and the tool and chip The contact length becomes shorter, reducing the basis of the built-up edge.
