Background technology
Hard brittle material such as silicon crystal, sapphire, quartz crystal materials etc. are obtaining high speed development in recent years, and cut this
The technique of a little materials mainly has inside and outside circle cutting and saw blade cutting etc., the advantages of due to saw blade cutting:Efficiently, it is inexpensive, narrow to cut
Stitch, pollute and small instead of other cutting methods substantially.And being cut with for diamond wire is significantly better than sand line in saw blade cutting
Cutting, the cutting efficiency of diamond wire is 3 times of abrasive wire sawing, and joint-cutting is smaller, and particularly silicon chip is cut, diamond wire saw
Silicon chip luminous energy conversion ratio is higher than the silicon chip of abrasive wire sawing.
The conventional production process of diamond wire is to use knockout method and sand buring method in the market, and its preparation method is by putting
Metal bare wire is released in line human relations, by processes such as oil removing, paint removal, nickel preplating, upper sand, nickel plating thickening, cleaning, drying, take-ups, and is fallen
The difference of sand method and sand buring method is that line knockout method when moving horizontally is that diadust is equably sprinkling upon to plating from the top of line
On the line moved in liquid, and sand buring method is to pass through mobile bare wire in diadust in plating solution.The disadvantage of both approaches
End is that speed is slow, and diamond particles receive the influence of resistance in deadweight and moving process, can not all be evenly distributed on wire
On, so as to influence cutting effect.

Embodiment 2
The production method of the diamond wire of the present embodiment comprises the steps:
The first step:The surface treatment of wire
It is that the grease and oxide layer on wire surface are cleaned first, the method for cleaning is first with water after caustic dip
Wash, then washed again with after mild acid wash.
Second step:Select suitable diamond particles
The size of diamond particles be it is different and determine according to the size of steel wire line footpath, the sizes of diamond particles with
10-50um is advisable, while the diamond particles selected should be crossed to be appropriate by treated cation, because the quality of diamond particles quality
The quality of the quality of diamond wire will be determined.
3rd step:Prepare diamond electroplating liquid
The quality of diamond electroplating liquid determines diamond particles and the bond strength of wire and the time of combination, so
Diamond electroplating liquid decides that diamond particles can is plated to steel wire bare wire in the production process of whole diamond wire
On, and the effect being plated on steel wire bare wire, so the formula is the important auxiliary link of the present invention.Electroplate liquid is matched somebody with somebody
Method processed is that every liter of electroplate liquid includes:Diadust 20-60 carats, nickel sulfamic acid 200-600g, nickel chloride 10-40g,
Boric acid 30-50g.
4th step:Diamond particles are electroplated onto on steel wire bare wire
The process is the important step of the present invention, and its method is that electroplate liquid first is put into upper sand launder to use, then
The bottom centre position of wire from upper sand cylinder is penetrated and passed again from the center on the top of upper sand cylinder, after putting on wire
Electroplate liquid is squeezed into upper sand cylinder with pump again.
The principle of this process is:Because wire is direct current negative pole, and upper sand cylinder is direct current positive pole, and wire
Again on the central shaft in upper sand cylinder, an electric field centered on wire is so formed in upper sand cylinder, in electric field
In the presence of, the nickel block in upper sand cylinder can decomposite the nickel ion being positive and enter in electroplate liquid, and the nickel ion in electroplate liquid
It can then dissociate on wire and nickel molecule is reduced into, together be wrapped the diamond particles adsorbed on wire in the form of nickel
It is rolled on wire, which forms an electroplating bath.In order that diamond particles can be adsorbed equably on wire, its
Method is to install an annular electromagnetic field in the lower section of upper sand cylinder, because diamond particles have been made at cation before this
Reason, specific method be first in one layer of nickel ion of diamond particle surfaces bag, when electromagnetism annular magnet rotate its magnetic line of force and
The motion of diamond particles in vertical direction in plating solution, the magnetic force in such plating solution will be converted into electric power so that diamond
Particle charge simultaneously has anode presentation, and wire is with cathodal current, so diamond particles are had rule by the effect of electrostatic
It is adsorbed onto on wire to rule, when in the upper sand cylinder that top is moved in the electromagnetic field of wire from below, institute on wire
The diamond particles of absorption will be together incorporated on wire with dissociating to the nickel molecule reduced on negative pole, and this is that plating is former
Reason.
5th step:Gu sand and take-up
The process be in order to consolidate the hold on diamond particles wire, it is first after diamond wire passes from upper sand cylinder
Nickel plating before this, to thicken coating, and make coating be diamond particles particle diameter 1/2 to 1/3, then successively through over cleaning, drying simultaneously
Take-up, you can obtain shaped article.
It is should be noted that when making and producing diamond wire instrument because electroplate liquid is acid, and need to heat, therefore selected
Material should be advisable with the material of acid-resistant and heat-resistant.And the plating solution in upper sand cylinder is input to from upper sand launder, to keep gold in plating solution
Hard rock particle is always maintained at suspended state, and plating solution must be inputted in sand cylinder all the way up, so should be provided with the upper end of upper sand cylinder
The outlet of backflow, such plating solution can recycle, and in summary, present invention process is simple, easy to operate, upper sand speed
It hurry up, diadust utilization rate is high, and the diamond wire produced is under Electronic Speculum, no accumulation, wire surrounding even particle distribution,
It is a kind of method of efficiently quick production diamond wire.
