Abstract
The present invention provides a kind of twolip diamond cutter for engraved stone, and including the matrix knife bar of hard alloy, the end processing of described matrix knife bar is fluted, and cutter grain is fixed on described groove by brazing mode；The rake face of described cutter grain and the intersection place of rear knife face one are main cutting cutting edge one, and it is main cutting cutting edge two that the rear knife face two of described cutter grain is provided with the intersection place of the chip area formed by two groove planes, described chip area and described rear knife face two。Comparing to the single cutting edge of Bartlit engraving, the main cutting cutting edge two processed by chip area substantially increases working (machining) efficiency, also reduces the loss of cutter simultaneously, adds cutting-tool's used life。
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 engraving precision is had significantly high demand by exquisiteness and levels of precision that its works are expressed。Existing graver many employings single-blade for processing of stone designs, and not only working (machining) efficiency is low, and tool loss is fast。
Summary of the invention
In view of this, the present invention provides a kind of twolip diamond cutter for engraved stone, and main cutting edge adopts Double-blade structure, and two main cutting edges simultaneously participate in cutting, under the premise ensureing engraving precision, is greatly improved stock-removing efficiency and improves working (machining) efficiency。
The technical solution used in the present invention is particularly as follows: a kind of twolip diamond cutter for engraved stone, and including the matrix knife bar of hard alloy, the end processing of described matrix knife bar is fluted, and cutter grain is fixed on described groove by brazing mode；The rake face of described cutter grain and the intersection place of rear knife face one are main cutting cutting edge one, and it is main cutting cutting edge two that the rear knife face two of described cutter grain is provided with the intersection place of the chip area formed by two groove planes, described chip area and described rear knife face two。
The angle that said two groove plane is formed 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 including 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 distance that cutter grain is top。
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, processing has auxiliary knife face one and auxiliary knife face two；Described rear knife face one is combined into front cutting edge mouth with the intersection of described auxiliary knife face one, described rear knife face two with the intersection of described auxiliary knife face two and the intersection of described auxiliary knife face one and described auxiliary knife face two。
The beneficial effect comprise that: the cutter of the present invention adopts twolip cutting, effectively extends cutting-tool's used life；And hard alloy knife bar meets the strength and toughness demand of high-speed cutting；Special cutting edge design avoids occurs that in the course of processing cutting edge collapses the defects such as scarce；Size that different choice according to quality of stone material is different or the angle of each cutting edge；High rigidity and the high-wearing feature of the cutter grain of diamond are enough to ensure that the demand that stone material is cut。
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, it is possible to be more completely more fully understood that the present invention。Accompanying drawing described herein is used for providing a further understanding of the present invention, embodiment and explanation thereof to be used for explaining the present invention, is not intended that inappropriate limitation of the present invention。

Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme 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, including the matrix knife bar 1 of hard alloy, the end processing fluted 2 of matrix knife bar, cutter grain 3 is fixed on groove 2 by brazing mode；The structure of cutter grain includes rear knife face 1 and the rear knife face 26 of rake face 4 and symmetrical configuration, on rear knife face 26, processing has the chip area 7 formed by two groove planes, in order to ensure 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 the intersection place of rear knife face 26 and chip area 7 is main cutting cutting edge 29。
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 in 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 including alloy-layer 10 and PCD layer 11, and in order to ensure that main cutting cutting edge 29 has enough intensity, main cutting cutting edge two must be placed in PCD layer 11。
In order to easy to process, can also again after intersection place, the top car of knife face 1 and rear knife face 26 go out to assist knife face 1 and auxiliary knife face 2 13, rear knife face 1 is combined into front cutting edge mouth with the auxiliary intersection of knife face 1, rear knife face 27 with the intersection of described auxiliary knife face 2 13 and the intersection of auxiliary knife face 1 and auxiliary knife face 2 13, in engraved stone process, two main cutting cutting edges is played certain assosting effect。
Additionally, the diameter of section of matrix knife bar 1 is preferably 6～13mm, and the groove installed surface of cutter grain 3 is preferably 5～10mm to the distance that cutter grain 3 is top。
As it has been described above, embodiments of the invention have been explained, it is clear that if essentially without depart from the present invention inventive point and effect, will be readily apparent to persons skilled in the art deformation, be also all contained within protection scope of the present invention。
