Problems solved by technology

[0003] The technical problem of the existing diamond wire is that as the diamond wire gradually becomes thinner and thinner, the diameter of the diamond particles used is getting smaller and smaller. At present, it has gradually evolved to use 70μm core wire plus 5 / 10μm diamond powder to produce outer diameter For diamond wires below 85μm, the cutting edge height is usually less than 5μm, and due to diamond wear in the later stage of cutting, the cutting edge height may even be lower than 2μm, so the coating substrate will rub against the material to be cut, thereby increasing the cutting resistance. The breaking force of the diamond wire generally does not exceed 18N, resulting in a greater risk of wire breakage

Embodiment approach 1

[0041] (1) Pay-off: power pay-off, under constant speed of 5-10N tension

[0042] (2) Surface cleaning: After treatment with alkaline degreasing agent solution at 60±5°C, washing water, 10% sulfuric acid solution at 40±5°C and washing water respectively, the core wire with clean surface can be obtained;

[0043] (3) Surface pretreatment: The core wire that has been cleaned on the surface is deposited on the surface with a layer of nickel layer medium with high adhesion and fine grains through the flash nickel plating process. By adjusting the core wire speed, solution formula, current, pH value, Temperature, stirring and other parameters are used to adjust the grain size and thickness distribution of the nickel coating.

[0044] (4) Diamond attachment: diamond particles with a specification of 5 / 10 are attached to the surface of the core wire by electrochemical co-deposition technology.

[0045] (5) Diamond consolidation: connect the core wire with diamond particles to the ca...

Embodiment approach 2

[0051] The difference from Example 1 is that the self-lubricating material used is graphite fluoride, the additive used contains cetyltrimethylammonium chloride, the diamond particle size is 4 / 8, and other steps are the same as in Example 1.

Embodiment 3

[0053] The difference from Example 1 is that the self-lubricating material used is PTFE particles with an equivalent diameter of 10-1000 nanometers, and the specification of the diamond particles is 30 / 40. Other steps are all the same as in Example 1.

Abstract

The invention relates to the technical field of diamond wires, in particular to a self-lubricating diamond wire and a production method thereof. The method comprises the following steps of (1) paying off, (2) surface cleaning, (3) surface pretreatment, (4) diamond adhering, (5) diamond solidification, (6) coating of an antifriction coating and (7) drying. After the structure and method are adopted, the self-lubricating diamond wire and the production method have the following advantages that firstly, compared with common electroplated diamond wires, the diamond wire produced through the technique has the self-lubricating performance, the friction resistance during cutting can be reduced, and the cutting process is smoother; secondly, the diamond particle holding strength is not obviously influenced after the surface antifriction coating is adopted, and the wire breakage risk can be effectively reduced; thirdly, by controlling technique parameters, nickel lattices in the antifriction coating are distorted, dislocation motion is hindered, thus, lattice deformation resistance is increased, the surface hardness is improved while the friction resistance is lowered, and the diamond holding force is improved; and fourthly, the production technique does not need to be adjusted greatly, and the quality can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of diamond wire, in particular to a self-lubricating diamond wire and a production method thereof. Background technique [0002] The current diamond wire is consolidated with diamond on the surface of the steel wire by electroplating nickel metal. Generally, the thickness of the coating reaches 1 / 3-1 / 2 of the diameter of the equivalent circle of diamond abrasive grains. During the cutting process, the surface of the nickel coating will also come into contact with The material to be cut increases the cutting resistance. As the customer's requirements for the diameter of the diamond wire become thinner, its breakage also decreases sharply, and the cutting resistance increases the risk of wire breakage. After adopting the self-lubricating coating technology, the frictional resistance can be greatly reduced, thereby reducing the risk of wire breakage while maintaining the cutting force, and further improving the...
