Embodiment 1

[0017] Take nickel sulfate 100 kg / kl, nickel chloride 5 kg / kl, sodium hypophosphite 20 kg / kl, sodium sulfate 20 kg / kl, sodium acetate 10 kg / kl, sodium citrate 3 kg / kl liters, lactic acid 60 kg / kl, diamond powder mixed particles 5-100μm 20 kg / kl. The pH value of the above-mentioned solution is between 1.5 and 6, and the temperature is controlled between 70 and 90°C, and it is ready for use.

[0018] Clean the stainless steel wire (generally 0.1-1mm) for degreasing and impurity removal, heat treatment at a temperature of 200-500°C for about half an hour, and then clean it with water for de-impurity removal. When performing electrospraying, the winding wire passes through the cathode and anode plating solution pool, and the relative movement is 5-30 m / min, and then the coating is inspected. Generally, the thickness of the coating can be controlled between 5-80 μm. After testing, heat treatment is carried out at 200-500°C for about half an hour, and then cleaning with water to re...

Abstract

An apparatus for preparing the stainless steel-diamond wire used to cut crystal steel by electric coat-spray method is composed of pulse power supply, coating pen, magnetic circulating pump, plating liquid concentration balancing pool, air compressor, and wire paying off and winding unit. Its method includes such steps as washing stainless steel wire, heat treating, washing, coating while spraying, testing, heat treating, washing and examining.

Description

Technical field: [0001] The invention relates to a device and method for producing diamond cutting wire for cutting crystals. Background technique: [0002] Semiconductor crystals, such as single crystal silicon, single crystal germanium, gallium arsenide, and optoelectronic crystals, such as lithium niobate and quartz, are growing in diameter. How to cut these brittle and precious crystals efficiently and at low cost has become a key issue in crystal processing. A crucial question. [0003] The traditional method of cutting crystals is to use diamond internal circular saw blades. This method can only cut crystals with a diameter less than 6 inches in one piece, and the saw blade is thicker, resulting in large crystal loss and low efficiency. In recent years, foreign countries have developed multi-knife wire cutting machines, which use reciprocating smooth high-strength steel wires with a diameter of 0.15 to 0.3 mm to add S:C and other abrasives to grind and cut with cryst...
