Requirement, it is rigidly good to first have to cutter, especially roughing tool；It is small, mutual that cutter will also possess high precision, antivibration and thermal deformation
It is transsexual good, convenient for rapid changing knife etc. a little；Cutter life is high simultaneously, and cutting ability is reliable and stable；It is organic in digital control processing mobile phone
During glass shell, usually hole opening technology, the diamond tool that tradition uses carry out mobile phone glass by numerically-controlled machine tool
Tool can only often carry out the production process of a bore process, also need to replacing other fine grinding knife in the technique of fine grinding refine
Tool, it is so time-consuming and laborious；And after bistrique long-time grinding production, bistrique body can be produced because of local pyrexia
Raw vibrations, it is impossible to the good machining accuracy for ensureing accurate grinding；It is ground so providing a kind of new mobile phone circular hole that is suitable for
The unusual necessity that just seems for the diamond cutter cut.
The content of the invention
The goal of the invention of the utility model：
Primarily to a kind of new diamond cutter for being suitable for the grinding of mobile phone circular hole is provided, during grinding
Roughing and the finishing passes of circular hole technique are once completed, effectively raise the production efficiency of grinding, while cause drill bit
Local friction is effectively avoided to send out jerk thermogenetic in grinding process, the effective size essence for ensureing processing endoporus
Degree improves the quality of production of product, improves the economic benefit of enterprise.
The technical solution of the utility model is：
A kind of diamond bit is provided, including grip shank, is provided in the front end of grip shank in hierarchic structure distribution
The bed of material is refined, fine grinding material matrix is electroplate on the fine grinding bed of material, the front end of the fine grinding bed of material is provided with the transition shaft shoulder, in transition
The front end of the shaft shoulder is provided with the corase grinding bed of material in cylindrical structure, and diameter of section and the section for refining the bed of material for roughly grinding the bed of material are straight
Footpath is equal and its Concentricity tolerance is no more than positive and negative 0.01mm；Coarse grained abrasive matrix is also electroplate on the corase grinding bed of material.
It has also been uniformly arranged and coarse grained abrasive matrix interval along the cylinder deployed configuration face of the corase grinding bed of material in the corase grinding bed of material
The auxiliary abrasive matrix of arrangement has also been uniformly arranged multiple tippers on the cylindrical structure developed surface of the corase grinding bed of material, this inclines
Skewed slot is along developed surface in 45 ° of settings.
The thickness of the auxiliary abrasive matrix is 2mm.
The width of the tipper is 2mm, depth 2mm.
The smart abrasive matrix uses the diamond dust of 1000 mesh, and the coarse grained abrasive matrix uses the diamond dust of 400 mesh.
The beneficial effects of the utility model are：
The diamond cutter of the structure setting is especially suitable for mobile phone circular hole Grinding Process, one during grinding
The secondary roughing for completing circular hole technique and finishing passes, effectively raise the production efficiency of grinding, while drill bit is existed
Local friction is effectively avoided to send out jerk thermogenetic in grinding process, is effectively guaranteed the size essence of processing endoporus
Degree improves the quality of production of product, improves the economic benefit of enterprise.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.
As shown in Fig. 1~2, a kind of diamond bit is provided, including grip shank 1, is provided in the front end of grip shank and is in
The fine grinding bed of material 2 of hierarchic structure distribution is electroplate with fine grinding material matrix 3 on the fine grinding bed of material, is set in the front end of the fine grinding bed of material
There is the transition shaft shoulder 4, the front end of the transition shaft shoulder is provided with the corase grinding bed of material 5 in cylindrical structure, the section for roughly grinding the bed of material is straight
Footpath is equal with the diameter of section for refining the bed of material and its Concentricity tolerance is no more than positive and negative 0.01mm；It is also electroplated on the corase grinding bed of material
There is coarse grained abrasive matrix 6.
It has also been uniformly arranged and coarse grained abrasive matrix interval along the cylinder deployed configuration face of the corase grinding bed of material in the corase grinding bed of material
