Description
[technical field]
The present invention relates to technical field of laser processing, more particularly to a kind of environmental pollution are small, high in machining efficiency, product is good
Product rate is high, the laser accurate processing method of the high diamond cutter of automation degree of controllability.
[background technology]
In Ultra-precision Turning, diamond cutter is to influence one of key factor of machined surface quality.
Conventional diamond cutter sharpening technology mainly has at present：Mechanical sharpening method, electric spark sharpening method and laser ablation
Method etc..
Mechanical grinding method is traditional diamond cutter sharpening process, and its essence is exactly diamond and diamond
To grinding.For commercial Application angle, mechanical grinding method technique is most simple, and equipment is also than less expensive.But this grinding method
It is limited to grind rotating disk, it is impossible to process high-precision shaped form diamond cutter.
Chinese patent CN105415099A discloses a kind of monocrystalline cutter preparation technology.Its step is：1) sorting, selection is suitable
The cutter for closing sword length is processed；2) face is thrown, the single-chip of well cutting is ground on cast iron abrasive disk；3) weld, throw
The good single-chip of light need to be cleaned up, and be matched with corresponding cutter hub, to ensure rake face to the height at cutter hub center, afterwards true
Welded in empty stove；4) roughly grind, roughly ground using skive；5) refine, fine grinding is enterprising in cast iron abrasive disk
OK, before grinding, first by bortz powder and olive oil or abrasive pastes are mixed into, are then coated with, in grinding panel surface, placing one section
Time makes abrasive pastes be fully infiltrated into the cast iron hole of abrasive disk, then is carried out back and forth in grinding panel surface with a larger diamond
Pre-grinding, further to strengthen tessellation of the bortz powder in cast iron hole, during grinding, typically fills the diamond of grinding
It is clipped on fixture, exposes the face that need to be ground, blade takes inverse mill, that is, grinding direction to point to cutter hub from blade during fine grinding, and
And on the premise of the amount of feeding is given, appropriate increase milling time.Machinery sharpening can efficiently process that to obtain surface clean and tidy
Diamond cutter, but this method can not process curved diamond cutter, and due to machinery sharpening have it is discontinuous
Percussion, obtained diamond cutter jaggedness and metamorphic layer thickness be larger, and surface roughness is also larger.
The removal of material is realized in the galvano-cautery effect that electric spark sharpening is discharged by high-frequency impulse between two electrodes.When processing
Each side as electrode of workpiece and instrument in machining medium by high frequency pulse power supply energy, machined material is produced
Electric discharge corrosiveness, the essence of this corrosiveness is the friction that machining medium ionizes the electronics to be formed or cation high-speed motion
Heating, and hit moment thawing and the blast action of the produced localized hyperthermia of electrode effect.
Chinese patent CN101327564A discloses a kind of processing method of diamond cutter cutting edge.Its step is：A) will
Required shape and size are ground to after tool matrix heat treatment；B) in diamond blade welding position relief grinding and blade kissing
Knife face after the tool matrix of conjunction, tool matrix should subtract 0.05-0.2mm than diamond blade compact dimensions, to enter to cutter
When row cutting edge is processed, tool matrix is not worked into；C) diamond blade is welded on tool matrix relevant position exactly；d)
By diamond blade with required shape is laser-cut into, 0.15mm surplus is uniformly flowed out；E) copper rod is pressed to diamond blade
The size and dimension smart car of cutting edge is installed on numerical control electric spark into electrode；F) by cutter positioning on the correct position of lathe,
Guarantee correctly to coincide with electrode；G) electrode rotary is made close to cutter, until forming suitable discharging gap；H) according to cutting edge
Surplus chooses the power parameters such as the rough machined electric current of electric spark, pulse width, makes electrode electric close to being produced during diamond blade
Erosion effect removes unnecessary diamond；I) electrode is redressed, the power supplys such as electric current, the pulse width of finishing ginseng is selected
Number, makes electrode produce galvanic corrosion close to diamond blade and plays finishing function, to obtain high-precision size, shape and cutting edge.Electricity
Erosion effect processing cutting edge, does not make the linearity and finish of cutting edge be significantly improved.
Laser ablation method makes irradiation table using 1-100Hz single beam or multi beam Nd-YAG laser irradiation diamond cutter surface
Face issues raw burn erosion in localized hyperthermia's effect.Using the instantaneous power density feature of laser ultrahigh, can moment to diamond tool
Tool produces small destruction, and due to the processing characteristics of laser, laser damage region is smaller, and acquisition tool surface is bright and clean, edge
Clearly.
