Description

A kind of anti-weldering formula minor diameter diamond cutter

Technical field

The utility model is related to diamond cutter fields, more particularly to a kind of anti-weldering formula minor diameter diamond cutter.

Background technology

Since single-crystal diamond is a kind of crystalline solid of single C atoms, lattice structure belongs to isometric centroid cubic crystal system (one The highest crystallographic system of kind atomic density), the interatomic link keys of C are SP3 hydridization covalent bonds, have very strong binding force, stability And directionality, it is most hard substance known to nature, microhardness is up to 10000HV.Its unique physical and mechanical property of institute, Do not allow to be also easy to produce glutinous knife and built-up edge when not only cutting, and theoretically blade can also obtain the straightness and cutting edge of a knife or a sword of atom level Sharp degree.So single-crystal diamond is the accurate ideal material with ultra precision cutting cutter of manufacture.

But.Cutter hub diameter of the cutting diameter of minor diameter Single-crystal Diamond Cutters mostly on 1~3mm or so, handle of a knife D1 is then 0.7~2.5mm or so, and the blade of general single-crystal diamond blade designs the axial location in handle of a knife, then in radius side It is to the cutter hub height H of single-crystal diamond blade is supported：

H=1/2d1-h

In formula：

H-is single-crystal diamond blade thickness, generally takes 0.3-1mm.

Referring to Fig. 1, method of this welding single-crystal diamond on cutter hub in Fig. 1 is face-bonding, monocrystalline diamond cutter Blade 11 on piece 10 is located in the plane at 21 place of axis of handle of a knife 20, the plane where blade 11 and single-crystal diamond blade Welding surface 30 between 10 and the cutter hub 21 of handle of a knife 20 is not in the same plane.It can be seen that face-bonding does not influence major diameter cutter, But it is very big to the intensity effect of small-diameter cutter, can not bear cutting when resistance to cutting and fail.

In the modern manufacturings such as 3C electronics, medical instrument, precision instrumentation, photoelectron, computer, radar, optics field In it is smaller and smaller to the processing request size of facet, small fillet surface and micro hole, to the quality of finished surface, especially surface Roughness and dimension precision requirement are higher and higher, and hard alloy cutter and high-speed steel tool can not be competent at all, traditional Buddha's warrior attendant The face-bonding of stone cutter cannot achieve the manufacture of small cutting edge diameter 1~3mm cutters again.The processing method of other material removals, such as Electric machining, plasma process and ultrasonic wave processing etc., not only efficiency is low but also uncertain can reach surface processing request.

Thus applicant carried out beneficial exploration and trial, result of the above problems is had found, will be detailed below being situated between The scheme to continue is generated under this background.

Utility model content

The technical problem to be solved by the utility model is in view of the deficiencies of the prior art with defect and provide a kind of anti- Weldering formula minor diameter diamond cutter.

Following technical scheme may be used to realize in the technical issues of the utility model is solved：

A kind of anti-weldering formula minor diameter diamond cutter, including handle of a knife and cutter hub and the welding in described handle of a knife one end are set Diamond blade on the cutter hub, the blade of the diamond blade are located in the plane where the axis of the handle of a knife, It is characterized in that, the welding surface between plane and the diamond blade and cutter hub where the blade is in the same plane.

In a preferred embodiment of the utility model, the structure of the handle of a knife is staight shank or Morse taper shank or 7:24 cones Handle or high-speed cutting handle of a knife 1:10 short cone hollow handles.
