The processing process of the automobile wheel hub is: positioning
and clamping the outer circle and end face of one end of the blank,
and then proceed to sequential processing: rough and finish turning
the outer circle, end face and inner hole of the other end to
ensure the length and finishing allowance of the inner hole;
Process the inner hole and end face for positioning and clamping,
rough and finish turning the outer circle, end face, inner hole and
groove at the other end; use the end face and small inner hole for
positioning and clamping, drill each tire threaded mounting hole,
drill the threaded bottom hole, and tap ; On the dynamic balancing
machine, carry out dynamic balance measurement on the processed
brake drum, measure the unbalanced amount and unbalanced position,
and mark the unbalanced position.
Application of SUS303
SUS303 is used to process deep holes and complex-shaped parts that
are difficult to machine with SUS304.
On the other hand, its corrosion resistance is not as good as
SUS304, so it is not suitable for applications in contact with
seawater or corrosive fluids.
Machinability of SUS303
In SUS303, MnS reduces the fracture energy of machined parts,
thereby reducing cutting resistance and improving tool holding
force.
In addition, SUS304 chips are difficult to split and are easily
caught in the tool, while SUS303 is easy to split and it is easier
to process deep holes.
SUS303 corresponds to austenitic stainless steel. Austenitic
stainless steels are corrosion resistant and can be welded by TIG
welding and plasma welding. In addition, even in a high-temperature
environment, there is little decrease in strength. Also, since
austenitic stainless steel is non-magnetic, it will hardly stick to
magnets.
As a unique feature of SUS303, it has the same machinability as
irons such as SS400 and S45C.
For example, SUS304, which is widely distributed in the market, has
a band-like chip when cutting, which is easy to entangle with the
blade. On the other hand, SUS303 contains a large amount of
phosphorus (P) and sulfur (S), so chips discharged during cutting
become finer. The finer the chips, the better they come out of the
blade, the easier they are to clean, and the less risk of scoring
or injuring the material being machined.
SUS303 is a material that is less likely to seize than SUS304.
Aging is the phenomenon in which surfaces stick to each other when
metals rub against each other and cannot be removed.
