This part is made of SUS304 material,without any surface
treatment.The processing of this part is relatively simple:turning
the outer shape and then drilling side holes to complete the
part.The biggest challenge for this part is how to maximize
machining efficiency as much as possible.SUS304 is a widely used
austenitic stainless steel,known for its excellent corrosion
resistance and workability,and is widely applied in various
industrial fields.However,due to its unique physical
properties,such as low thermal conductivity and a tendency to work
harden,machining SUS304 also presents certain challenges.
1, Coated Tools:This product selects coated tools,which can improve
the tool's heat resistance and wear resistance,extend tool life,and
reduce wear during processing.
2, Cutting Speed:Based on the hardness and thermal conductivity of
SUS304,choosing the appropriate cutting speed is crucial.Too high a
cutting speed can lead to tool overheating and wear,while too low
can affect machining efficiency.The generally recommended cutting
speed is 160-180 meters per minute.
3, Feed Rate:The selection of feed rate needs to balance tool wear
and workpiece surface finish.Too high a feed rate can cause edge
wear,while too low can lead to increased surface roughness.The
generally recommended feed rate is 100-200 meters per minute.
4, Cutting Depth:The choice of cutting depth should be determined
based on tool size and cutting performance to avoid excessive tool
wear or vibrations during cutting.Too large a cutting depth can
easily lead to tool breakage,while too small can reduce machining
efficiency.
