In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of bearing machining NC cutting tool, including
Knife bar and the annular cutter hub for being mounted on knife bar end, the operative end surface periphery of this annular cutter hub are equipped with annular land, this annular sword
Annular chip pocket is provided on rake face with rear side, the operative end surface of the annular chip pocket inner circumferential is equipped with annular convex platform；Institute
It states in annular chip pocket, be equipped with multiple chip breaking salient points around annular cutter hub center line.
Further improved scheme is as follows in above-mentioned technical proposal:
1. in above scheme, the chip breaking salient point is set as 6, and two of adjacent chip breaking salient point and operative end surface center
The angle of line is 60 °.
2. in above scheme, the annular land is negative chamfered edge land, and the angle value of negative chamfered edge is 12 °.
3. in above scheme, the junction of the annular convex platform and annular chip pocket is rounded down, value R0.5mm.
4. in above scheme, the rake face to the inclination angle in annular chip pocket direction be 15 °.
5. in above scheme, the flank of the annular cutter hub is obliquely installed.
6. in above scheme, the knife bar end is equipped with the mounting groove with fixation hole, inserted in the mounting hole of the cutter hub
There is the fixed screw being threadedly connected in fixation hole.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
1, the metal that annular land generates is discharged by annular chip pocket in the utility model bearing machining NC cutting tool
Bits, and using the reasonable chip breaking of cooperation, the chip removal of chip breaking salient point in the annular convex platform and annular chip pocket on rear side of annular chip pocket, no
It is only avoided that metal fillings is accumulated in annular land, influences the finish on workpiece to be machined surface, moreover it is possible to which rapid cooling avoids heat
It is accumulated in annular land, annular land hardness is caused to reduce and influence turnery processing.
2, the utility model bearing machining NC cutting tool has circle in the junction of annular convex platform and annular chip pocket
Angle further increases chip removal, the chip breaking effect of annular chip pocket and annular convex platform.
3, the utility model bearing machining NC cutting tool is designed by negative chamfered edge, is enhanced annular land intensity, is reduced
Tipping improves cutter hub quality.
