Background
The electroplated diamond cutting line is a cutting tool formed by consolidating diamond micro powder on a steel wire by adopting an electro-deposition nickel method, and is mainly used for cutting and processing hard and brittle materials such as silicon crystals, sapphire and the like.
The main production process of the electroplated diamond cutting wire is as follows: pre-processing, pre-plating, sanding and thickening of the steel wire. The pretreatment mainly refers to the processes of alkali washing, acid washing, cleaning and the like of the steel wire, and the impurities such as oil stains, rust layers and the like on the surface of the steel wire are removed. The preplating is to preplate a layer of nickel on the surface of the steel wire so as to improve the binding force between the plating layer and the steel wire. Sanding refers to the preliminary consolidation of diamond abrasives to a steel wire substrate by electrodeposition of metallic nickel. Thickening refers to firmly holding the preliminarily consolidated diamond in the sand on the steel wire substrate by further electrodepositing metal. The production process of the electroplated diamond cutting wire is generally carried out continuously, and the surface of the produced electroplated diamond cutting wire is provided with a coating containing diamond particles which are distributed continuously, and the diamond cutting wire can be called a cutting wire with the diamond particles distributed continuously. The cutting wire with the diamond particles distributed continuously mainly has the following problems during the use process: (1) the chip containing space is small, and the chip containing space formed among the diamond particles is easy to block in the cutting process, so the cutting efficiency is low; (2) the cutting wire has a low fluid carrying capacity and the lubrication and cooling of the cutting zone is insufficient.
The diamond cutting line coated with sand in sections refers to that an electroplated layer containing diamond particles on the diamond cutting line is discontinuous and is divided into an electroplated section and an unplated section, wherein a diamond particle plated layer is consolidated on the upper surface of the electroplated section, and no diamond particles are consolidated on the unplated section. The electroplating sections and the non-electroplating sections are distributed at intervals. The plating section plays a role of cutting, and the non-plating section mainly plays a role of chip containing and carrying cutting fluid. Therefore, the cutting efficiency of the diamond cutting line with sand on the segments is high, and the cutting area is cooled sufficiently. The existing subsection sanding method mainly comprises three methods, one method is to adopt a covering method to separate a non-sanding electroplating section from electroplating solution, and the application number is as follows: CN201410136210, the operation of the steel wire in the electroplating solution is intermittent during the operation, the production efficiency is low, the equipment is complex, and the mechanism for driving the covering mold in the electroplating bath is easily damaged by the diamond in the electroplating solution. The second method is to apply insulating coating on the non-electroplating section to realize sand coating on the section, such as application number: CN201710683794, the scrap-containing capacity of the non-electroplating section is reduced. The third is to prevent the sand on the non-plating section by the insulation shielding device moving together with the cutting line, as the application number: CN201410329088, although the disadvantages of the above two methods are solved, the sanding device has more moving parts, complex equipment and poor reliability of continuous operation, and the electroplated section and the non-electroplated section of the produced electroplated diamond cutting line have obvious diameter difference, so that the cutting process has large impact and is easy to break.
