Abstract
The invention provides a minitype superhard blade which comprises a base. Tool grooves are machined in the sharp corner positions of the external end outline polygon of the base, and a superhard tool bit is soldered in each tool groove in a brazing mode. The polygon comprises any polygonal shape with equal edges or unequal edges, and single tool groove or two tool grooves are machined in each sharp corner or interval sharp corners of the polygon. The maximum effective cutting depth of tool bits used by a traditional brazing superhard blade is more than 3.5mm, while the maximum effective cutting depth of the minitype superhard blade is only 1.5-2.8mm, based on the fact that tool bit materials are saved by more than 50%, the fastness degree of the brazing of the tool bits and the base can be guaranteed, and the service life is not influenced.
Description
Technical field
The invention belongs to machining tool technical field, be specifically related to a kind of mini superhard cutting blade.
Background technology
Along with the development of industrial cutting technique, guarantee, under the prerequisite of qualification rate, cut quality have been proposed to the higher market demand.In normal actual use, the real cutting depth of braze welding type blade can not surpass 1mm, and existing braze welding type blade is in order to make cutter head firmly be welded on matrix, for 3.5mm is above, (wherein Ap value is maximum effective cut depth to the Ap value of the cutter head using, maximum effective cut depth is the length of side of cutter head), cause the material using to increase, increased the cost of cutter.Along with cutter market competition is growing more intense, when promoting quality, only have continuous cost squeeze, rationally utilize material, produce more economical cutter, just can there is competitiveness.
Summary of the invention
In view of this, the invention provides a kind of mini superhard cutting blade, the soldering blade tip size that the size of super-hard cutter bits is relatively traditional reduces more than 50%, and firm welding, the risk coming off without cutter head, in guaranteeing use procedure, in functional reliability, reduce the material of tool bit part, reduced cost.
The technical solution used in the present invention is specially: a kind of mini superhard cutting blade, comprise matrix, and described matrix is polygon, described polygonal wedge angle position is processed with cutter groove, in described each cutter groove, by brazing mode, is welded with super-hard cutter bits.
The maximum effective cut depth of described cutter head is 1.5-2.8mm.
Each wedge angle position of described polygon outer end is processed with cutter groove.
A plurality of wedge angles interval of described polygon outer end is processed with cutter groove.
Described polygonal each wedge angle position is processed with single or two cutter grooves.
Described polygon is equilateral or unequal-sided arbitrary polygon.
The material of described super-hard cutter bits is cubic boron nitride (CBN), polycrystalline cubic boron nitride (PCBN), polycrystalline diamond (PCD), composite polycrystal-diamond (PDC) or CVD diamond.
Described super-hard cutter bits is made mini superhard cutting blade after being welded in the cutter groove of matrix after cutter grinding machine sharpening.
The beneficial effect that the present invention produces is:
The maximum effective cut depth of the cutter head that 1, soldering superhard cutting blade is in the past used is for more than 3.5mm, and the maximum effect cutting-in that has of mini superhard cutting blade of the present invention is only 1.5-2.8mm;
2, traditional cutter head area is 7-10 ㎜
2, and cutter head area of the present invention is only 3-6 ㎜
2, at tool tip material, saved on more than 50% basis, guarantee that cutting-in is unaffected;
3, the firm degree of guaranteeing cutter head and matrix welding by brazing mode, there is not obscission in cutter head, has guaranteed the functional reliability of superhard cutting blade, and service life is unaffected.
