The influence of sharpness of cutting tool on processing of steel 07X16H4B
The quality of steel processing in industry is characterized by many parameters (for example, the presence of micro-outbursts, flakes and sagging, level of roughness, etc.). These parameters are influenced by such factors as cutting conditions (cutting speed, feed and depth), technological equip...

| Summary: | The quality of steel processing in industry is characterized by
many parameters (for example, the presence of micro-outbursts,
flakes and sagging, level of roughness, etc.). These parameters
are influenced by such factors as cutting conditions (cutting
speed, feed and depth), technological equipment parameters and
characteristics of the cutting tool (geometry of the cutting part,
hardening coating, sharpness of the blade). The purpose of the
work is to study the treated surface of corrosion-resistant steel
07X16H4B with a tool sharpened by classical and high-speed
methods. To achieve this goal, the following tasks are solved: the
final carbide cutting tool is manufactured and sharpened, tests of
the cutting tool on steel 07Kh16N4B are carried out; quality control
of the treated surface is carried out. The results of experiments on
blade cutting of stainless steel with a tool with different sharpness
of the blade are presented. Based on these results, it is concluded
that the best result of processing high-strength corrosion-resistant
steel grade 07X16H4B is obtained by a tool sharpened by a highspeed method with a blade sharpness ρ = 3 ... 5 μm. The obtained
results allow substantiating recommendations on the required
sharpness of carbide cutting tools used in the processing of highstrength hard-to-work steels. |
