Diamond grinding wheel for natural diamond polishing, it can replace the polycrystalline diamond (PDC), processing of diamonds. Diamond and ceramic binder with common characteristics, combined with the agent plays a role in holding abrasives, diamond grinding wheel and gives Dongguan certain geometric shapes. It is the Dongguan diamond grinding wheel performance is an important symbol. Binding agent made from thermoplastic resin binder plus a variety of filler composition, (the widely used phenolic resin, polyimide resin, a small amount of application; apply some filler metal oxide). Diamond grinding wheel used in the nature of binding agent is the amount of the various components of the binding agent, many physical properties, mechanical properties and grinding performance has a great impact, therefore, be the material for the workpiece, the performance to be selected, in order to achieve good the results. Diamond and diamond grinding wheels with vitrified common characteristics, and general corundum, silicon carbide abrasive compared to its grinding force, grinding temperature is relatively low, abrasive wear is relatively small; can be adapted to a variety of coolant effect; grinding abrasive good shape retention, high precision grind the workpiece; abrasive there are more pores, grinding and heat conducive chip, clogging, easy to burn the workpiece; abrasive from good sharp, trimming long time interval, relatively easy trimming. Therefore, vitrified diamond abrasive used in some foreign countries is increasing.
Under normal circumstances, diamond wheel, there are four cylindrical grinding techniques, the following are brief. 1 diamond grinding wheel vertical way. The efficiency of this method is relatively slow, but its quality is very good, relatively speaking, and similar products is relatively low compared to the roughness. When the grinding, diamond grinding wheel rotation is very high, is seen in the rotation process. Workbench is a composite longitudinal operation, during each operation or process in the wheel will have a supply, the excess will be touched off something cut off. (2) into the grinding skills. Also known as horizontal milling method. This and the first one is relatively speaking very efficient, it also has the same shortcomings, its grinding force is very large, and the temperature is relatively high, so there should be plenty of time grinding the cooling liquid . Diamond grinding wheel rotation is an active force, craft and wheel rotational movement causes a continuous movement of supplies. The table is not a wheel vertical movement operation, the width of the diamond grinding wheel width is relatively large, has been the size of the ground to use it so far. 3 composite grinding skills. This is a synthesis of the above two. Composite grinding and grinding methods are more efficient, the relative quality; it is rather good, in the other advantages also have some advantages. Grinding, we use the workpiece in the form of coarse segmentation, with the rest of the disc treatment. 4 The last method is a deep grinding method. Its production efficiency is very high, but the wheel repair technique is more complex, the overall structure of the workpiece requirements are relatively high, there must be plenty of cut and cut lengths. During the grinding time. Wheel a whole will have a stepped shape. The speed of the workpiece and the means are very slow. Use the rest of the grinding Longitudinal grinding.
