Specific implementation mode
Specific implementation mode one:As shown in figures 1-4, the processing method of three tooth non-working surface lathe tools described in present embodiment It is to be realized according to following steps:
Step 1: rough forging:Forging blank size is the cuboid of 130mm × 32mm × 210mm;
Step 2: Milling Process:Forging blank in step 1 is subjected to milling, size is 130mm × 27mm after milling The cuboid of × 204mm;
Step 3: scribing by bench worker:Trim line on the right side of cutter hub is drawn on cuboid upper surface in step 2 after milling;
Step 4: Milling Process:Line made allowance 2mm, cutter hub are pressed in shape on the right side of Milling Process cutter hub, cutter head wire cutting part 2 × 45 ° of right side tail portion chamfering;
Step 5: Milling Process:Milling Process cutter hub left upper portion step surface, step surface height are 1.5mm, and step surface is long Spend high-volume 2~3mm, Milling Process shoulder section lower both sides chamfering;
Step 6: heat treatment:HRC67~69 of hardening are carried out to tool bit part, to shank portion harden HRC40~ 45;
Step 7: blasting treatment:Blasting treatment is carried out to the cutter hub after hardening in step 6;
Step 8: flat surface grinding:It is ground tool bit part and each face of shank portion, is ground 1.5mm step horizontal planes, ensures phase The opposite depth of parallelism is 0.01, and the verticality of adjacent surface is 0.01, then goes magnetic treatment;
Step 9: cutter sharpener is ground:It is ground the vertical plane of 1.5mm step surfaces;
Step 10: wire cutting machine tool is processed:Wire cutting tool bit part molded line and each portion's relief angle, the relief angle of molded line left part It it is 2 °, the relief angle of molded line right part is 6 °, 2 × 2 undercut of wire cutting, and 1.5mm step surfaces is vertical in wire cutting step 9 Face ensures that the depth of parallelism is 0.01, and verticality 0.01, tool bit part size is 51.52 ± 0.015, two side tool of wire cutting cutter hub Shoulder portion;
Step 11: linear cutter molded line part rake face, goes rake face surplus;
Step 12: cutter sharpener is ground:It is ground 14 ° of rake face anterior angle, is reserved along cutting edge rake face front end is contour 0.2mm lands grind parts of tooth relief angle, increase 14 ° of relief angle;
Step 13: cutter sharpener is ground:Grinding positioning metafacial angle, grinding cutter end surface;
Step 14: cutting tool dulling is handled;
Step 15: laser inscription:Icking tool has figure number and date of manufacture;
Step 16: each side deburring, sharp edge is blunt, packaging.
It is physically crossing before Milling Process in step 3, is being to be unlikely to make to process to the layout line when Milling Process At mistake.
In step 1 to step 5 be roughing, needed in cutter hub large area remove part it is complete before the heat treatment At after heat treatment, cutter hub hardness increases, and so that difficulty of processing is improved, therefore Milling Process is put before the heat treatment.
Wire cutting machine tool is discharged by molybdenum filament in step 10, carries out cutting entity, and for the workpiece of molded line complexity, most Good processing method is exactly linear cutter, and the three tooth non-working surface lathe tools that the present invention processes, cutting edge part is by circular arc straight line Complicated molded line is constituted, only wire cutting could be completed.
Wedge angle can be formed in step 12 between rake face and flank, if not staying 0.2mm lands, work is processed in lathe tool Wedge angle will collapse tooth at once when part, damage, stay land be in order to make cutter prolong the service life, if land is wide, Jiu Huishi Lathe tool cutting edge is too blunt, and turning effect is bad, and land is narrow, loses the effect for staying land, thus select margin width for 0.2mm, it is in order to which in turning, flank will not interfere with workpiece to increase relief angle.
Specific implementation mode two:The material of forging blank is M42 high-speed steel in present embodiment step 1.So operation, Meet the requirement of three tooth non-working surface lathe tool material materials.Other compositions and connection relation are same as the specific embodiment one.
Specific implementation mode three:The HRC68 that hardens is carried out to tool bit part in present embodiment step 6.So operation, can To increase tool bit part hardness, extend the service life of tool bit part, it is indeformable during guarantee tool bit part use.Other groups At and connection relation it is the same as one or two specific embodiments.
Specific implementation mode four:HRC41~44 of hardening are carried out to shank portion in present embodiment step 6.So behaviour Make, shank portion hardness can be increased, extends the service life of shank portion, it is indeformable during guarantee shank portion use. Other compositions and connection relation are the same as the specific implementation mode 3.
Specific implementation mode five:HRC42~43 of hardening are carried out to shank portion in present embodiment step 6.So behaviour Make, shank portion hardness can be increased, extends the service life of shank portion, it is indeformable during guarantee shank portion use. Other compositions and connection relation are identical as specific implementation mode five.
Specific implementation mode six:As shown in figure 3, milling cutter shoulder portion lower part both sides chamfering in present embodiment step 5, Left side chamfering is 20 °, and right side chamfering is 30 °.So operation, Milling Process are put before the heat treatment, and large area is needed in cutter hub The part of removal is completed before the heat treatment, easy to process.Other compositions and connection relation and specific implementation mode one, two, four Or five is identical.
Specific implementation mode seven:As shown in figure 4, it is 6 ° that positioning surface relief angles are ground in present embodiment step 13, Grinding cutter end surface inclination angle is 6 °.So operation reduces location area, it is fixed to improve since 6 ° of relief angles being arranged at positioning surface Position precision.Other compositions and connection relation are identical as specific implementation mode six.
