Abstract
The invention provides a double-edge diamond tool for engraving stone. The double-edge diamond tool comprises a base arbor made of hard alloy; a groove is formed at the end of the base arbor and a cutting point is fixed in the groove by means of brazing; the intersected position of a front cutting face and a first back cutting face of the cutting point serves as a first main cutting edge; a chip removing slot formed by two groove planes is arranged on a second back cutting face of the cutting point; the intersected position of the chip removing slot and the second back cutting face serves as a second main cutting edge. Compared with a tool with single cutting edge for stone engraving in the prior art, the double-edge diamond tool has the advantages that processing efficiency is increased greatly, loss of the tool is reduced while service life of the tool is prolonged due to the second main cutting edge which is processed through the chip removing slot.
Description
Technical field
The present invention relates to sintered carbide tools technical field, be specifically related to a kind of twolip diamond cutter for engraved stone.
Background technology
Engraved stone is as a kind of molding mode of Arts works, and the exquisiteness that its works are expressed and levels of precision have very high demand to engraving precision.The existing graver for processing of stone adopts single-blade design more, and not only working (machining) efficiency is low, and tool loss is fast.
Summary of the invention
In view of this, the invention provides a kind of twolip diamond cutter for engraved stone, main cutting edge adopts Double-blade structure, and two main cutting edges participate in cutting simultaneously, under the prerequisite of assurance engraving precision, can greatly improve stock-removing efficiency and improve working (machining) efficiency.
The technical solution used in the present invention is specially: a kind of twolip diamond cutter for engraved stone, comprise the matrix knife bar of carbide alloy, and the end of described matrix knife bar is processed with groove, and cutter grain is fixed on described groove by brazing mode; The intersection place of the rake face of described cutter grain and rear knife face one is main cutting cutting edge one, and the rear knife face two of described cutter grain is provided with the chip area being formed by two groove planes, and the intersection place of described chip area and described rear knife face two is main cutting cutting edge two.
The angle that described two groove planes form is 90～120 °.
The groove depth of described chip area is 0.1～0.4mm.
The cutting angle that described main cutting cutting edge one becomes with main cutting cutting edge dimorphism is 45～120 °.
Described cutter grain is the composite bed that comprises alloy-layer and PCD layer, and described main cutting cutting edge two is placed in described PCD layer.
The groove installed surface of described cutter grain is 5～10mm to the top distance of cutter grain.
The diameter of section of described matrix knife bar is 6～13mm.
Described rear knife face one and described rear knife face two are symmetrical plane.
Between described rear knife face one and rear knife face two, be processed with auxiliary knife face one and auxiliary knife face two; Described rear knife face one is combined into front cutting edge mouth with intersection and the described auxiliary knife face one of described auxiliary knife face two with the intersection of described auxiliary knife face two with the intersection of described auxiliary knife face one, described rear knife face two.
The beneficial effect that the present invention produces is: cutter of the present invention adopts twolip cutting, has effectively extended the service life of cutter; And carbide alloy knife bar has met the strength and toughness demand of high-speed cutting; Special cutting edge design has avoided occurring in process that cutting edge collapses the defects such as scarce; According to the angle of the different size of the different choice of quality of stone material or each cutting edge; The high rigidity of adamantine cutter grain and high-wearing feature are enough to the demand that assurance is cut stone material.

The specific embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
A kind of twolip diamond cutter for engraved stone as Figure 1-5, a kind of twolip diamond cutter for engraved stone, comprises the matrix knife bar 1 of carbide alloy, and the end of matrix knife bar is processed with groove 2, and cutter grain 3 is fixed on groove 2 by brazing mode; The structure of cutter grain comprises rear knife face 1 and the rear knife face 26 of rake face 4 and symmetrical configuration, on rear knife face 26, be processed with the chip area 7 being formed by two groove planes, in order to guarantee the reliability of cutting and chip removal, the groove depth of chip area 7 is 0.1～0.4mm, and the angle of two groove plane formation is preferably 90～120 °.
So far, the intersection place of rake face 4 and rear knife face 1 is main cutting cutting edge 1, and rear knife face 26 is main cutting cutting edge 29 with the intersection place of chip area 7.
In engraved stone process, along with the rotation of cutter, the operation profile of two main cutting edges forms a taper seat, and the cone angle of this cone face is defined as the cutting angle of cutter, and cutting angle is preferably 45～120 °.
Cutter grain 3 is the lamination layer structure that comprises alloy-layer 10 and PCD layer 11, and in order to guarantee that main cutting cutting edge 29 has enough intensity, main cutting cutting edge two must be placed in PCD layer 11.
For easy to process, also intersection place, the top car of rear knife face 1 and rear knife face 26 goes out to assist knife face 1 and auxiliary knife face 2 13 again, rear knife face 1 is combined into front cutting edge mouth with intersection and the auxiliary knife face 1 of described auxiliary knife face 2 13 with the intersection of auxiliary knife face 2 13 with the intersection of auxiliary knife face 1, rear knife face 27, in engraved stone process, two main cutting cutting edges is played to certain booster action.
