Abstract
The utility model discloses a MCD and PCD integrated composite cutter, which comprises a structure main body, wherein the structure main body comprises a cutter bar, an MCD sheet and a PCD sheet, the lower end of the cutter bar is provided with a mounting groove, the MCD sheet and the PCD sheet are both welded and fixed in the mounting groove, and the MCD sheet, the PCD sheet and the cutter bar are of an integrated structure; the MCD sheet and the PCD sheet are welded on the cutter bar to form an integrated structure, and besides the characteristic that the PCD sheet can be used for conventional chamfering and hole milling, the cutter also has MCD chamfering capable of realizing highlight effect, so that the cutter body cost and the cutter changing time of a client can be reduced, and the processing efficiency is improved; the cutter has good processing effect, long service life, high efficiency and high quality and yield.
Description
Technical Field
The utility model relates to a processing cutter field especially relates to an integrative compound cutter of MCD, PCD.
Background
The PCD cutter is artificial polycrystalline diamond, and is formed by sintering natural or artificially synthesized diamond powder and a binding agent in a certain proportion under a high-temperature and high-pressure environment to form a PCD compact with fixed diameter and thickness; MCD is a synthetic single crystal diamond made by high temperature and pressure process, synthesized in an oxygen-free, high temperature and pressure environment.
The friction coefficient of the MCD cutter is low, so that a bright mirror surface effect can be cut; the PCD cutter has higher hardness and longer processing life; in the cutting process of the mobile phone cover plate, the two cutters are often selected according to the actual processing procedure, so that the cutters need to be frequently changed, the processing efficiency is influenced, and the processing cost is increased; therefore, an MCD and PCD integrated composite tool is provided.
Disclosure of Invention
In order to overcome the not enough of prior art scheme, the utility model provides an integrative compound cutter of MCD, PCD can solve the problem that the background art provided.
The utility model provides a technical scheme that its technical problem adopted is:
MCD, integrative compound cutter of PCD, including a structure subject, structure subject includes cutter arbor, MCD piece and PCD piece, the mounting groove has been seted up to the lower extreme of cutter arbor, MCD piece and PCD piece equal welded fastening in the mounting groove, MCD piece, PCD piece and cutter arbor formula structure as an organic whole.
Further, the MCD sheet is arranged at the upper end of the PCD sheet;
furthermore, a cutting inclined plane is arranged on one outward side of the MCD sheet;
further, a cutting part protruding outwards is arranged at the middle section of the PCD piece;
further, a knife edge is arranged on the outward side of the PCD piece and the MCD piece;
further, the section of the cutter rod is rectangular.
Compared with the prior art, the beneficial effects of the utility model are that:
the MCD and PCD integrated composite cutter of the utility model has the advantages that the MCD sheet and the PCD sheet are welded on the cutter bar to form an integrated structure, besides the characteristic that the PCD sheet can be used for conventional chamfering and hole milling, the cutter also has MCD chamfering which can realize highlight effect, the cutter body cost and the cutter changing time of customers can be reduced, and the processing efficiency is improved; the cutter has good processing effect, long service life, high efficiency and high quality and yield.

Fig. 1 is a schematic view of the overall structure of the present invention.
Reference numbers in the figures: 1, cutting a tool bar; 2-MCD sheet; 3-a PCD wafer; 4, mounting a groove; 5-cutting an inclined plane; 6-a cutting part; 7-knife edge.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The MCD and PCD integrated composite cutter of the present invention is described in detail with reference to fig. 1 as follows:
MCD, integrative compound cutter of PCD, including a structure subject, structure subject includes cutter arbor 1, MCD piece 2 and PCD piece 3, mounting groove 4 has been seted up to the lower extreme of cutter arbor 1, MCD piece 2 and PCD piece 3 equal welded fastening in the mounting groove 4, MCD piece 2, PCD piece 3 and the 1 formula structure as an organic whole of cutter arbor.
Preferably, the MCD chip 2 is disposed at the upper end of the PCD chip 3;
preferably, the side of the MCD sheet 2 facing outwards is provided with a cutting inclined plane 5;
preferably, the middle section of the PCD wafer 3 is provided with a cutting part 6 protruding outwards;
preferably, a blade 7 is arranged on the outward side of the PCD piece 3 and the MCD piece 2;
preferably, the cross-section of the tool bar 1 is rectangular.
The working principle is as follows: the PCD sheet 3 and the MCD sheet 2 are both welded on the cutter bar 1, the cutter bar 1 is fixed on cutting equipment, products to be processed are fed to different parts of a cutter to carry out different processing procedures, the PCD sheet 3 has higher hardness and is used for conventional chamfering and hole milling, and the MCD sheet 2 is used for highlight chamfering; two types of machining and cutting are carried out on one cutter, tool changing is not needed, machining efficiency can be improved, and machining cost is reduced.
To sum up, the MCD and PCD integrated composite cutter of the utility model has the advantages that the MCD sheet and the PCD sheet are welded on the cutter bar to form an integrated structure, besides the characteristic that the PCD sheet can be used for conventional chamfering and hole milling, the cutter also has MCD chamfering which can realize high light effect, the cutter body cost and the cutter changing time of customers can be reduced, and the processing efficiency is improved; the cutter has good processing effect, long service life, high efficiency and high quality and yield.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
