As shown in Figures 1 to 4, a kind of indexable turning blade for cutting high temperature alloy, turning insert body contours profile
Using ISO international standards：DNMG150608.By the standard it is found that the appearance profile of the blade horizontal cross-section is 2 55 ° of angles
The diamond shape alternately constituted successively with 2 125 ° of angles；Blade includes mainly upper surface 3a, the lower surface 3b opposite with upper surface, shape
The cutting edge 1 and circular arc knife that four sides 9, side and upper and lower surface between upper surface and lower surface described in Cheng Yu are crossed to form
Sharp 8, mounting hole 4 in blade center position is set.
Blade upper surface 3a is equipped with rake face 5 with the lower surface outer peripheries 3b, and uses larger anterior angle, preferably 14-
16 °, the wide 0.7-0.9mm of rake face.Side 9 is vertical with upper and lower surface, and relief angle is 0 ° and upper surface 3a and the complete phases of lower surface 3b
Together；Cutting edge 1 uses keen edge, and carries out sphering processing, and sphering value is 0.015-0.025 mm.Larger lathe tool anterior angle,
Cutting edge is sharp, and cutting is smooth, can effectively reduce cutting resistance, can be used for the finishing of high temperature alloy.Sharp cutting edge carries out
Sphering processing, suitable sphering value so that cutting edge strength can be enhanced while cutting edge is sharp again, therefore the blade can be also used for
The semifinishing of high temperature alloy.
Rake face 5 is correspondingly arranged on volume bits platform 6 toward 4 direction of mounting hole, and it is inclined-plane volume bits platform which, which considers platform to be worth doing, with horizontal direction
Angle be set as 20-26 °, angle is gentle；Rake face 5 is connected smoothly using arc groove 7 with volume bits platform 6 namely circular arc
Slot 7 be placed in rake face 5 and volume bits 6 between, and with it is both tangent；The arc radius of arc groove 7 is using 0.5-0.7 mm.Before
Knife face, transition arc slot, volume bits platform three form wider chip space, and groove width is preferably 1.8-2.2mm, groove depth 0.33-0.39
Mm, volume bits in this way are smooth, and chip removal is smooth, and then it is small to rub, and cutting temperature is low, and cutter bonding abrasion is small.
Blade upper surface 3a and lower surface 3b is considered to be worth doing in volume and is set four support floors between platform and mounting hole, and respectively first
Support floors 2a, the second support floors 2b, third support floors 2c, the 4th support floors 2d, are distributed evenly in mounting hole four
Week.When processing, using a face in upper and lower surface as cutting face, another is positioning surface, equally distributed four on positioning surface
Support floors uniform force improves blade positioning precision, firmly installs, therefore cutting process vibrations are small, cutting is stablized, can be effective
Improve workpiece machining surface quality.
Upper surface 3a and lower surface 3b is containing there are four cutting edge 1 and two circular arc points of a knife 8.Four sides 9 and upper following table
Face is vertical, and relief angle is 0 ° and upper surface 3 is identical with lower surface 3b.When the cutting edge 1 or circular arc point of a knife 8 on one of face
All abrasion after, blade upper and lower surface can be overturned, using on another face cutting edge 1 and circular arc point of a knife 8 continue to process,
The service life of blade is improved in this way.
The present invention by taking the D-shaped horizontal cross-section appearance profile of indexable insert tip, throw away tip DNMG150608 as an example, but not limited to this, together
Sample is suitable for T shapes, V-arrangement；The present invention can also be blade increase TiALN physics coatings, without departing from the present invention spirit under,
All equivalent technical solutions are within the scope of protection of the invention.
After the present invention uses this structure, due to sharp using larger lathe tool anterior angle, cutting edge, cutting is smooth, thus energy
Cutting force is effectively reduced, the finishing of high temperature alloy is can be used for；
The chip space of the present invention is wider, is equipped with the gentle volume of rake face, transition arc slot, angle and considers platform to be worth doing, therefore rolls up and consider smooth, excretion to be worth doing
It is smooth, and then it is small to rub, cutting temperature is low, and cutter bonding abrasion is small.
The blade cut resistance of the present invention is small, and cutting temperature is low, and cutter bonding abrasion is small, therefore blade adds under normal pressure cooling
Work enhances cooling effect without high pressure cooling, and cutter life is long.
