With the continuous development of the profession of machining and fine
machining, the precision requirements of machining are also constantly
advancing. Fine machining technology is a manufacturing technology used in
recent years, so it is more suitable for thin-walled parts. In addition, how to
advance the processing power during the processing of large mechanical parts and
better service became a big problem at that time. The editor reviewed the
relevant materials and summarized the details as follows:

Advance fine parts processing power:In the process of fine parts processing, common problems such as
accelerated tool wear, poor machined surface integrity, and difficulty in chip
removal will appear, which seriously affect the quality, production cycle and
processing cost of fine parts of such materials.

According to the theories of metal technology, metal cutting, and fine
parts processing, the difficulties in the processing of the above materials are
analyzed, and a set of effective stainless steel material drilling, reaming, and
boring processing technologies are explored.

The machining of fine parts requires ultra-lubricated machining surface and
high machining accuracy. This requires a tool with a high standard life. Whether
the tool is worn or not will be based on whether the quality of the machined
surface has dropped out of tolerance.

The standard life of diamond tools is very high, and the tool wear is very
slow during high-speed cutting. Therefore, in ultra-fine cutting, the cutting
speed is not restricted by the tool life, which is different from the general
cutting rules.

　　The selection of fine parts processing parameters 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 tool with a larger rake angle when processing plastic
materials, you can effectively suppress the formation of the buildup. This is
when the rake angle of the tool increases, the cutting force decreases, the
cutting deformation is small, and the tool and chips The touch length becomes
shorter.
