Description
Technical field
The utility model patent is related to a kind of for the semi-finished hard alloy rotatable lathe tool of 300M unimach
Piece, and in particular to 300M unimach DRY CUTTING semifinishing indexable turning blades.
Background technology
300M steel is as a kind of typical low-alloy super-strength steel, not only with superhigh intensity characteristic, and with good
Good corrosion resistance and anti-fatigue performance, are widely used in the important load-carrying member in space flight and aviation.But what material had
High intensity and high rigidity make it be shown in cutting process, and chip is difficult to control to, tool wear is serious, machined surface
The phenomenons such as deterioration.The utility model blade is proposed in this context, to 300M unimach DRY CUTTING semifinishings
Play a positive role.
The content of the invention
The purpose of this utility model is to provide a kind of rhombus 300M unimach DRY CUTTING semifinishing index lathe
Blade, solving existing blade, in cutting 300M unimach, chip is difficult to control to, tool wear is serious, machined surface matter
The problems such as amount deteriorates.
The utility model patent adopts the technical scheme that to solve above-mentioned technical problem：The utility model includes 80o water chestnuts
Shape turning insert main body（1）, the center position of blade is provided with circular hole（1-1）, vane body（1）Rake face be provided with chip-breaker
（2）, vane body（1）Four sides be provided with main cutting edge（4）, vane body（1）Four angles be provided with Circular Nose Cutting Edge（8）, it is main
Cutting edge（4）With Circular Nose Cutting Edge（8）By transitional edges（7）Connection, in Circular Nose Cutting Edge（8）Nearby it is respectively equipped with crescent raised（6）, in knife
The crescent of piece main body is raised（6）Vicinity is provided with groove for cuttings（5）.
The utility model has following beneficial effect：The utility model turning insert is in Circular Nose Cutting Edge（8）Nearby it is respectively equipped with crescent moon
Shape is raised（6）, while increasing the cutting hardness of cutter, the effect of fractureing is played to chip, the chip after fractureing is recessed by chip removal
Groove（5）Outflow, effectively realizes the function of being flowed out with chip that fractures of chip.Main cutting edge（4）, Circular Nose Cutting Edge（8）And transitional edges
（7）On be equipped with chamfered edge（3）, strengthen blade cut intensity, reduce tool failure.Chip-breaker 2, crescent are convex in process
Rise（6）And groove for cuttings（5）The space of chip breaking can be increased, accelerate the chip rate of outflow, so as to reduce built-up edge, tipping
The problems such as.The utility model turning insert improves chip difficulty and fractureed, the problems such as chip breaking hardly possible is discharged, and obtains cutting force and cutting temperature
To effective control, the precision of finished surface and the service life of blade are improved.
