Abstract
The utility model provides a W type polycrystalline cubic boron nitride blade, including composite construction W type blade body, be provided with the fixed slot on the composite surface of blade body, the fixed slot is located the center of blade, and the shape of cross section of fixed slot is the same with the shape of cross section of blade body. Compared with the prior art, the utility model discloses the fixed slot that is provided with on the stationary plane of blade body, fixed slot prevent that the blade from at the lower departure from the cutter arbor of the effect of vibration, having improved the security of working. And provide the fixed slot on the stationary plane of blade, and prevent that the blade from under the effect of atress and vibration, taking place to deflect, improve workpiece surface's machining precision.
Description
Technical field
The utility model belongs to superhard cutter technical field, is specially a kind of W type polycrystalline cubic boron nitride cutting.
Background technology
W type blade combines by original trilateral and 80 ° of diamond shaped insert to develop, and is commonly used to replace 80 ° of diamond shaped insert to use, and more than 80 ° of diamond shaped insert cutting edges of two, and economy better, is the first-selection of general turnery processing. When blade is arranged on knife bar, what generally adopt is that upper pressure type compresses, but the quality of fit between blade and knife bar exists certain deviation, and cutter is adding man-hour, blade has certain displacement relative to knife bar, thus cause the sideslip of point of penetration, cause the workpiece of processing defective, and when tool sharpening, vibrate bigger, there will be the phenomenon that blade flies from knife bar, danger is higher, also affects the processing quality of blade face. In the prior art, the generation for preventing above phenomenon having, blade face is provided with frustum type groove, which prevent the phenomenon generation that blade flies from knife bar, but, due to the frustum type groove adopted, blade is when by power and vibration, there will be the phenomenon of blade deflection, cause the workpiece accuracy of processing not up to standard.
Practical novel content
The technical problems to be solved in the utility model is: blade, when by power and vibration, there will be the phenomenon of blade deflection, causes the workpiece accuracy of processing not up to standard, for solving the problem, it is provided that a kind of W type polycrystalline cubic boron nitride cutting.
The purpose of this utility model realizes in the following manner:
A kind of W type polycrystalline cubic boron nitride cutting, comprises composite structure W type blade body, the composite surface of blade body is provided with pickup groove, and pickup groove is positioned at the center of blade, and the cross section shape of pickup groove is identical with the cross section shape of blade body.
The degree of depth of pickup groove is 0.5-3mm.
The thickness of blade body is 4-10mm.
The drift angle of pickup groove is consistent with the drift angle direction of blade body.
Blade body is one side composite structure or two-sided composite structure.
Relative to prior art, the pickup groove that the utility model is provided with on the fixed face of blade body, pickup groove prevents blade from flying under the effect of vibration from knife bar, it is to increase the security of work.And pickup groove is set on the fixed face of blade, it is prevent blade under the effect by power and vibration, deflects, it is to increase the working accuracy of workpiece surface.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation one.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model front view two.
Wherein, 1 is blade body; 2 is pickup groove.
Embodiment
As shown in Figure 1-Figure 3, a kind of W type polycrystalline cubic boron nitride cutting, comprises composite structure W type blade body 1, blade body composite surface 1 is provided with pickup groove 2, pickup groove 2 is positioned at the center of blade body 1, and the cross section shape of pickup groove 2 is identical with the cross section shape of blade body 1. Adopt pickup groove 2, prevent blade deflecting by during power.
The degree of depth of pickup groove 2 is 0.5-3mm. The thickness of blade body 1 is 4-10mm. The drift angle of pickup groove 2 is consistent with the drift angle direction of blade body 1, the transposition of blade time easy to use.
Blade body 1 is one side composite structure or two-sided composite structure, and Fig. 1 is two-sided composite structure, and Fig. 3 is one side composite structure.
Claims (5)
