At present domestic because blade 40 can't be made voluntarily with to put the cutter groove 31 process technology precision that cooperatively interacts very high, and blade 40 all purchase from external, causes that finished parts are undue relies on external import, and no matter cost, manufacturing level all can not effectively be broken through.Because of shown in drawing, blade 40 is to be made into integration by carbonization wolfram steel, whole blade 40 is a kind of thickness homogeneous, the double helix form of cutter hub rule distorted shape, causing its knife back is gradually toward the bottom curving by the top, the bottom is again toward the unidirectional curved arc shape that is of a side simultaneously, form the curved arc knife back 41, the curved arc knife back 41 itself promptly has the curved arc angle that the three-dimensional space changes, blade 40 whole thickness requirement homogeneous in addition, therefore blade 40 differs from the cutting face 42 of the curved arc knife back 41, also is the nearly double helix of angle changing, and hereat the processing request of blade 40 is to changing arc angle in this way, domestic this hierarchy of skill that do not reach as yet at present, one to being dependent on external import; Because of blade 40 forms in this way, cause and put cutter groove 31 and also must cooperate the curved arc knife back 41 need be processed into the curved surface 32 of tool curvature, so that can be consistent with the angle of the curved arc knife back 41.If it is not same to put the processing curvature of curved surface 32 of cutter groove 31, easily because of making bad distortion the (blade also can), blade 40 just is difficult to brazing and is combined in and puts cutter groove 31 places, cause closely connected each other degree greatly to reduce, if blade 40 positions are built on the sand, the revolving force of milling, the frictional resistance that produces high temperature and touch workpiece, all may cause blade 40 to burst apart, therefore blade 40 with put cutter groove 31 and cooperate because of processing the bad milling machine operation problem that causes, and the higher and shortcoming of excessively being dependent on foreign technology of cost, very important emphasis at present just.
In addition, 42 surfaces, cutting face of blade 40 are burnishing surface, therefore be incorporated into and put cutter groove 31, when cutting, can produce a problem, after being knife edge cutting, because 42 surfaces, cutting face are smooth, cutting swarf can flow toward whenever putting milling cutter 30 centers, opposite end, cutter groove 31 gap, thereby cutting swarf can productive set to cause the chip removal effect in this place not good, though end mill(ing) cutter 30 is 40 less because of blade, it is bigger at interval to put cutter groove 31, right chip removal effect does not very well perplex process operation also, especially the bad rotation high temperature that adds of chip removal, easily influencing the intensity of blade 40, is very important main points.
Main purpose of the present utility model is: a kind of blade of end mill(ing) cutter is provided, and mainly is the inclined-plane knife back that the knife back of blade is made as unidirectional inclined-plane; Put the relative inclined-plane of the cutter groove knife back and establish inclined-plane with no curvature; Make the inclined-plane knife back and to put the cutter groove good because of single face gradient adaptation, it is more easy to process, and reaches and needn't be dependent on external import, the purpose that significantly reduces cost.
Another purpose of the present utility model is: a kind of blade of end mill(ing) cutter is provided, and wherein the blade cut face is arranged with a concave arc road, to be easy to chip removal.
The utility model provides a kind of blade of end mill(ing) cutter, and side face is established a plurality of cutter grooves of putting in the end mill(ing) cutter below, and the knife back of blade is to be welded in to put on the cutter groove end face, and blade face in addition is the cutting face, it is characterized in that:
The knife back of blade is the inclined-plane knife back on unidirectional inclined-plane, this knife back with put the fixedly driving fit of inclined-plane that the cutter groove does not have turning curvature accordingly, and the cutting face entire body of blade is arranged with the concave arc road of a suitable radian.
The utility model compared with prior art, the true tangible progressive effect of tool:
1. blade 20 processing are more easy, because of its knife back be monocline to the inclined-plane knife back 211, closely be the single-screw body, very big difference arranged, thereby the plane gradient processing of the inclined-plane knife back 211 is easier with the double helix shape that has many curvature of space now, cooperation is simultaneously put cutter groove 11 and also is made as inclined-plane 12 relatively, hereat both easily reach the inclined-plane homogeneity of no curvature, guarantee that both weld the adaptation height, no matter are blades 20, put cutter groove 11 equal handling eases, need not to be dependent on external import, cost effectively significantly reduces; Because of both adaptation height, easy to manufacture, guarantee the steadiness of blade 20 cuttings more simultaneously, needn't worry that blade 20 has shakiness to cause the possibility of holding the angle to burst apart, and directly improves blade 20 cutting effects.
2. because cutting face 21 is provided with the concave arc road 22 of concave arc shape, therefore cutting swarf must be drained via concave arc road 22, can not accumulate in each gap of putting cutter groove 11, effectively improves the chip removal effect, impel the operation of cutting more smooth and easy, the service life of safeguarding end mill(ing) cutter 10.
