The borer that the present invention announces as shown in Figure 1-2, borer comprises cutter head 1 and blade 2, cutter head 1 comprises cutting face 11, clearance surface 12 and and is connected to refine face 13 between described cutting face 11 and clearance surface 12, described cutting face 11, clearance surface 12 are vertical with borer vertical section (as shown in Figure 2 A-A face) respectively with refine face 13, cutting face 11 becomes an obtuse angle with borer axis and described clearance surface 12 is arranged towards obtuse angle, and cutting face 11 and intersection, refine face 13 form blade 14.
Below borer of the present invention is introduced in detail.
Borer comprises cutter head 1 and blade 2, and blade 2 is clamped on rotary axis of machine tool, and outward appearance generally adopts cylindrical.Cutter head 1 is the funtion part of borer bore hole, generally comprise cutting face 11 vertical with borer vertical section (as shown in Figure 2 A-A face) respectively and clearance surface 12, in the present invention, cutting face 11 and clearance surface 12 junction are provided with refine face 13, can be used for cutting aperture, thus aperture roughness when reducing borer bore hole.
As the preferred embodiment of the present invention, the projection line length 0.05-0.15MM of refine face 13 on borer vertical section.
As the preferred embodiment of the present invention, the intersecting lens in clearance surface 12 and refine face 13 subpoint on borer vertical section (as shown in Figure 2 A-A face) is higher than the intersecting lens subpoint 0.01MM-0.08MM on borer vertical section of cutting face 11 with refine face 13.
As the preferred embodiment of the present invention, cutting face 11 is 3 ~ 7 degree with the angle in borer cross section (as shown in Figure 2 B-B face).
As the preferred embodiment of the present invention, R angle, blade 14 place is 0 ~ 0.08MM.
The borer processing method that the present invention announces comprises the following steps:
Hard pole supplied materials is provided;
Employing granularity is that the skive of 100-400 grinds out cutting face 11 and clearance surface 12;
Employing granularity is that the skive of 600-3000 grinds out refine face 13;
Employing granularity is the diamond Sandpapering blade 14 of 1000-3000.
As the preferred embodiment of the present invention, the step cutting face 11 of Sandpapering blade 14 becomes 40 ~ 50 degree of blades 14 that gently rub with sand paper with sand paper.
Borer process of the present invention is introduced below in conjunction with specific embodiment.
Carbide alloy wolfram steel pole supplied materials is provided;
By granularity be 200 diamond emery wheel be arranged on knife sharpener, make it rotate forward, carbide alloy wolfram steel pole is carried out abrasive lapping and goes out cutting face 11 and clearance surface 12, wherein cutting face 11 and the cross section angle of borer are 5 degree;
By granularity be 200 diamond emery wheel emery wheel remove, change the diamond emery wheel that granularity is 2000, grinding refine face 13, the projection line length of the refine face of making 13 on borer vertical section (as shown in Figure 2 A-A face) is 0.1MM, and the intersecting lens in clearance surface 12 and refine face 13 subpoint on borer vertical section (as shown in Figure 2 A-A face) is higher than the intersecting lens subpoint 0.05MM on borer vertical section (as shown in Figure 2 A-A face) of cutting face 11 with refine face 13;
