Aerospace, power generation equipment manufacturing,
construction, and the food industry are just a few of the
industries in which CNC Stainless Steel Parts is
currently in widespread use. As a result of severe
hardening during processing, high cutting temperatures,
and easy adhesion of chips, stainless steel exhibits the
characteristics of a typical difficult-to-machine
material in the following ways:Common problems that can
occur during the machining process of stainless steel
(STS), such as accelerated tool wear, poor surface
integrity of the machined surface, and difficulty in chip
removal, will almost certainly have an adverse effect on
the overall processing quality, production cycle, and
processing cost of the material parts containing CNC
Machining Stainless Steel, according to the ASTM
International Standard. A major objective of this section
of the Meet You Carbide Tech Department is to identify,
analyze, and summarize the difficulties that can arise
when processing stainless steel materials. It also offers
solutions, such as specific measures for stainless steel
cutting, as well as examples of typical products that can
be used as a starting point for research.
In the case of stainless steel materials, a variety of
factors contribute to the difficulty of the task at hand
when working with them.
You will notice that when you compare the strength and
hardness of what is stainless steel 304 to ordinary
steel, you will notice that it is considered to be of
medium strength and hardness in the manufacturing
industry. Despite the fact that it contains a significant
amount of elements such as Cr, Ni, and Mn, it possesses
excellent plasticity and toughness characteristics. Its
high temperature strength and high work hardening
tendency are also noteworthy, both of which contribute to
the cutting load of the material used in its manufacture.
As a side effect of this, some carbides are precipitated
within the austenitic tool steel during the cutting
process, causing the scratching effect on both the cutter
and workpiece to increase during the process and
decreasing overall cutting efficiency.
Because of plastic deformation that occurs during the
cutting of steel, especially austenitic stainless steel
(which has an elongation greater than 1.5 times that of
45 steel), the amount of cutting force required
increases.
An easily formed built-up edge can easily form during the
cutting process, which has a negative impact on the
surface roughness of the machined surface as well as the
likelihood of the tool surface peeling away during the
cutting process.
Closed and semi-closed chip cutters are more prone to
chipping than open chip cutters because of the clogging
that occurs during the cutting process. An increase in
surface roughness and tool chipping is observed as a
result of this process.
In structural applications,
steel">[color= rgb(0, 176, 240)">steel cnc
machining[/color"> has a linear expansion
coefficient that is approximately one and a half times
greater than that of carbon steel, making it a superior
choice. It is inevitable that the workpiece will be
subjected to some thermal deformation as a result of its
interaction with the cutting temperature, and this will
have an impact on the dimensional accuracy of the piece.
Rather than focusing on other considerations such as cost
or availability, the use of tool materials with high
hardness, toughness, and heat resistance should be
prioritized. Having a chemical affinity for stainless
steel is also important in the selection of these
materials. When processing STS components, it is
preferable to use high-performance high-speed steels
rather than standard high-speed steels such as
W2Mo9Cr4VCo8, W6Mo5Cr4V2Al, W10Mo4Cr3Al, and others,
rather than standard high-speed steels such as
W2Mo9Cr4VCo8, W6Mo5Cr4V2Al, W10Mo4Cr3Al,
It is widely accepted that, when looking at it through
the lense of the tool industry, the cutting performance
of tool materials is inversely proportional to the tool's
overall durability and productivity. It is also important
to consider how easily the tool material can be processed
because this has an impact on how well the tool performs
during the manufacturing and sharpening processes. It is
recommended that these tools be made from tool materials
with high hardness, high adhesion resistance, and tough-
tough properties, such as YG type hard alloys, which are
recommended for use in their manufacture. The use of YT
type hard alloys when processing austenitic is not
recommended, particularly when processing 1Gr18Ni9Ti
austenitic stainless steel, which is a high-temperature
stainless steel. The hard type of the YT variety should
be avoided if at all possible, according to the
manufacturer. Alloys are prone to tool wear as a result
of the formation of an affinity between titanium (Ti) in
stainless steel and titanium (Ti) in YT-based cemented
carbides as a result of the formation of the affinity
between titanium (Ti) in stainless steel. Thus, as a
result of this process, the titanium (Ti) contained in
the alloy is easily transported away by the chips
themselves. By analyzing production practice statistics,
it has been discovered that treating stainless steel with
YG532, YG813 and YW2 results in excellent processing
performance.
Cemented carbide tools are more suitable for cutting
than tools made of high-speed steel or hard alloy
materials, which are more suitable for cutting carbon
steel and aluminum. Cemented carbide is used in this
application because it has higher heat resistance and
wear resistance than high-speed steel, making it a better
choice in this situation. This is due to the presence of
the elements tungsten and cobalt, which give it an
exceptional toughness. Depending on the needs of the
customer, the tool can be modified to have a higher rake
angle and a sharper edge. As a result of these
considerations, the general consensus is that the use of
a tungsten-cobalt alloy is the most appropriate method
for processing . For rough machining and interrupted
cutting with high vibration, among other things,
tungsten-cobalt alloy knives should be used, as well as
for a wide range of other applications, such as drilling
and milling. If you compare the alloy to tungsten-cobalt-
titanium alloy, you will notice that it is not as hard
and brittle to the touch, and that it is also not as easy
to chip when compared to that alloy.
