Electroplated diamond, grinding head and so on, can carve and grind all kinds of precious stones, Jasper, ceramics and other industrial fine arts.
Electroplated diamond nail file, as one of the complete set of tools, is specially used for grinding and polishing nails.
Electroplated diamond grinding wheel for rubber sole trimming.
Basic process:
Selection of diamond:
Basic requirement:
I. appearance features: pure diamonds should be colorless and transparent (in fact, often due to impurities and defects and color). The synthetic diamond was observed under the microscope with eight faces, twelve diamond bodies, a cube and its aggregates. Often yellowish green, with more obvious impurity gray green, boron doped diamond was black.
II. performance: according to the JB2808-79 standard, the diamond is divided into JR1, JR2, JR, JR44 models. The higher the mark, the higher the hardness, the better the quality, the higher the price, but not the better the performance. Although JR4 diamond has the highest hardness, but its sharpness is lower than that of JR3 diamond. If both are used together, they can not only maintain good service performance, but also reduce production costs.
Impurity removal of diamond:
Magnetic impurities: synthetic diamonds have magnetic properties because they contain magnetic inclusions (catalysts, metals), and the higher the content of inclusions, the stronger the magnetism. The diamond with magnetic properties is not only difficult to be affected by impurities, low strength and poor heat resistance, but also has a bad influence on the quality of electroplating. It is easy to form nickel alloy and is difficult to select. The reason is that the magnetic inclusions are good conductors, which makes the insulation of diamond particles become worse and the electrical conductivity is weak. At the end of the power line clamp effect, the metal nickel is preferentially plated on the diamond pinch end which is high on the plating layer to form a nickel tumor. In order to avoid the influence of magnetic impurities, magnetic separation should be carried out before the diamond is used. It is better to do it on a special magnetic separator, or a magnet can be used to remove the particles with stronger magnetic susceptibility. Once diamond is found to be magnetic, all the diamonds should be returned.
Adsorption impurities: diamond is not pure, and its surface is always a layer of adsorption of impurities, if not removed in advance, the diamond powder will float in the electrolyte surface, can not be deposited on the substrate. Therefore, diamond must be treated with hydrophilic (wet) before use, and hydrophilic method can be used as reference material.
The basic principle of metal plating: plating bath, immersed in the bath to be plated with the negative electrode of the DC power supply is connected, the cathode (cathode) to metal plating and the DC power supply is connected (an anode), ion plating metal plating solution containing groove in the connected the power after the plating metal ions in the coating is formed on the cathode deposition
