martensite. In the machining process there will also be
great force action and extreme heat between the rake face
and the chips. So the chips tend to adhere to the blade and
form build-ups, and most of the heat produced in cutting
goes to the tool and rise the tool temperature, which
together worsen the tool wearing. As a result, common
tools can serve only for shorter life, work less efficiently
while more consumptively, and develop parts of much
lower precision and poorer surface quality. Thus it is
necessary to use tools special for stainless steel
machining, in this case professional tools from a Swedish
tool company and from OSG, and to define and control
exactly the suitable machine rotation speed, tool feed and
cut depth. Only by those means desirable cutting is
attainable.
IV. CLOSING REMARKS
Thanks to its good comprehensive performances,
particularly its high plasticity, tenacity, elongation,
contraction of area and impact toughness, steel
0Cr18Ni10Ti is desirable for production of coupling
disks. Use of the steel makes coupling easier to machine,
less costly, lighter and more easily to
assemble/disassemble. Moreover, it makes the coupling
more efficient and reliable in transmission operation. The
application of the steel is more advantageous than
previously used1Cr18Ni9Ti, 0Cr18Ni9 and/or 65Mn.
Nevertheless, in production of the material it is vital to
control its chemical composition, particularly the
percentages of Cr, Ni and Ti, and to control the technical
processes, so that intergranular corrosion is avoided.On
the basis of profiling&following control algorithm
processing is uesd in processing,and three elements of
machining by cutting is introduced to parctical use ,the
results is well.
Besides, it needs to adopt solution heat
treatment and stabilization treatment so as to improve and
better the material’s comprehensive performances and
corrosion-resistance.
