Abstract

The utility model relates to a composite diamond wire saw comprising a metal thread and an electroplated layer, wherein the electroplated layer is coated on the metal thread by electroplating for fixing the bottoms of diamond particles. The diamond particles are uniformly distributed on the electroplated layer. The wire saw is a tool to deposit a metal layer on the metal thread by an electroplating method and consolidate diamond abrasives in the deposited metal to manufacture a linear ultra-hard material. The metal coating is a binding agent; and the diamond abrasives are used for cutting process. The electroplating diamond wire saw can be manufactured into different diameters and lengths as required, and can be arranged on different devices to form different processing ways, such as reciprocating and recirculation way, high-speed belt-saw way, and linear cutting way. For the processing of hard-brittle materials, the wire saw cannot only be used for cutting slices, but also can be used for surface machining and hole grinding, thereby having a very wide application future.

Description

Composite diamond fretsaw

Technical field

The utility model relates to the diamond cut electrician testing tool technology field, specifically is a kind of composite diamond fretsaw, also claims diamond fret saw.

Background technology

At present, the instrument that is used to cut hard brittle material (for example: monocrystalline silicon crystal bar, gallium arsenide, quartz glass etc.) in the prior art is interior circle or cylindrical or annular diamond saw blade, once cuts an otch.Use this diamond saw blade cutting to make sheet material, effect is lower; Because saw blade is thicker, otch is bigger in the cutting sheet material, and material deterioration inside is bigger during the film-making material like this.

In order to improve stock-removing efficiency, also has a kind of scroll saw in the prior art, its normally linear wire; On the sawing device that uses this scroll saw; Often a wires is organized more and arranged setting, once can cut a plurality of otch, make multi-disc hard & brittle material sheet.Use existing scroll saw cutting sheet material, scroll saw is moved under the drive of power set, on scroll saw, spread the abrasive powders of immersion oil then, through falling abrasive material and the friction sawing workpiece between the workpiece on the scroll saw steel wire.This cutting is because abrasive material separates with scroll saw, and therefore, the cutting work efficiency is lower, and simultaneously, owing to moving of abrasive grain in working angles, therefore, the otch that on workpiece, cuts out is also bigger, and general otch will be about 1mm.Have again; Everywhere thickness difference is bigger on the sheet material that obtains of cutting like this, and warpage is serious, (remain in the cut channel on the face of cutting into slices dark); In order to make sheet material reach instructions for use; Also to carry out follow-up processing such as polishing, increase processing cost and production cycle, and cause the quality of the material of cutting into slices bad easily it.

The problems referred to above are all due to the scroll saw of the invar silk and the unpack format of the sand grains that is used for sawing.With above-mentioned scroll saw cut workpiece, want in the operation to spread abrasive material on the continuous online saw, extremely inconvenient, the immersion oil abrasive material also has bigger pollution to environment.

The utility model content

The less composite diamond fretsaw of otch that the technical problem that the utility model will solve produces when providing a kind of simple in structure, service life long, work.

For solving the problems of the technologies described above; The composite diamond fretsaw that the utility model provides; Be characterized in comprising: diameter be 0.33mm tinsel, be coated on the electrodeposited coating that is used for fixing the diamond particles middle and lower part on the tinsel through plating; Said diamond particles is uniformly distributed on the said electrodeposited coating continuously, and the size of diamond particles is the 3.0-4.0 order.

The technique effect that the utlity model has:

(1) the composite plating diamond fretsaw of the utility model is with the electric plating method a kind of linear tool made of superhard material that consolidating material and diamond abrasive is processed in the metal that deposits layer of metal (being generally nickel and nickel cobalt (alloy)) on the tinsel and depositing.The coat of metal is a bond, and diamond abrasive is used for cut.Electroplating diamond wire saw can be made into different diameters and length as required; Scroll saw can be contained in the different processing mode of formation on the different equipment, like reciprocation cycle (saw frame) formula, high speed band saw formula, line cutting type etc.To the processing of hard brittle material, scroll saw not only can dicing sheet, but also processing curve more can be used for the advanced study and training of aperture, and its application prospect is very wide.

(2) compare with other process technology, electroplating diamond wire saw has its unique advantage: compare with the free abrasive scroll saw, its working (machining) efficiency is higher, and energy consumption is lower; Can avoid batch mixing, granulation, sintering, welding loaded down with trivial details operations such as (or injection mouldings) in the sintered diamond tool manufacture process; Can be used for the non-conductor that electron discharge processing EDM can't process is processed; Diamond fretsaw is wrapped in around the cylinder, can repeatedly cut workpiece (like silicon rod) simultaneously, and can process a plurality of workpieces simultaneously; Owing to have spacing between the sintered diamond scroll saw beading, the spacing part possibly worn and torn prematurely and caused the fracture of steel wire (line), and adamantine continuous distributed in the electroplating diamond wire saw, can avoid the premature failure of scroll saw; Compare with band saw with annular saw, scroll saw can change cut direction neatly, can be used for the geometry of processed complex; Since wire saw diameters little (general＜1mm), it is little to add the man-hour kerf loss, this has great importance for the expensive semiconductor of cost and the processing of jewel.

(3) tinsel can be steel wire, stainless steel wire, tungsten silk, molybdenum filament and brass wire etc.For adapting to processing, matrix material should be selected tensile strength height and toughness material preferably for use; For ease of electroplating, its electrode potential should be lower than the current potential of plated metal (like nickel and nickel alloy).The definite of diameter wiry and length should decide according to machined material, processing mode and appointed condition.Generally speaking, for saving machined material, improve the wire that the line flexibility should be selected minor diameter for use as far as possible.

(4) electroplating diamond wire saw generally adopts the adamantine method manufacturing of composite plating nickel (or nickel alloy).The plating solution formula that composite plating nickel (or nickel alloy) diamond is used has multiple, is main salt with nickelous sulfate commonly.But the optimal selection for the electroplating diamond wire saw that bending motion is arranged then is to be the plating bath of main salt with nickel sulfamic acid, and it has that the nickel deposition velocity is fast, internal stress is little and advantage such as suitable isochronism, therefore is particularly suitable for electroplating diamond wire saw.
