Grinding wheel have different shapes and sizes, cut sheet plant, suitable for different grinding. Whereby the grinding wheel is rotated by the action of centrifugal force of a great, if there is not enough strength, cutting disc sales, grinding wheel will burst and cause a serious accident. Centrifugal force proportional to the square of the size of the grinding wheel peripheral speed, cut sheet, so when the circumferential speed of the grinding wheel to increase people - do not set the value, the centrifugal force would exceed the allowed range of wheel strength, so that the grinding wheel burst, so all kinds of grinding wheel sheets are provided for safe operating speed, with the speed of a grinding wheel is much lower burst of speed. Safe operating speed of the grinding wheel on a grinding wheel in order to identify the maximum operating speed, cut sheet production, the safety factor of 1.5. Here is an example of a grinding wheel in different sizes. Abrasive hardness depends mainly on the amount of binding agent is added to the number and density of abrasive grit off easily, said lower abrasive hardness; the other hand, indicates a high hardness. Hardness level is generally divided into super soft, soft, soft, medium, medium-hard, hard and superhard seven level, from these levels can be subdivided in a number of small magnitude. The method of measuring the hardness of abrasive, more commonly used hand cone, mechanical cone method, Rockwell hardness measurement method and blasting hardness assay. Hardness of the dynamic elastic modulus of the abrasive has a corresponding relationship, which is conducive to the determination by the abrasive audio method to represent the dynamic elastic modulus abrasive hardness. In the grinding process, high if they are grinding the workpiece material hardness, generally used in low hardness abrasive; on the contrary, the selection of high hardness abrasive. Diamond cutting sheet manufacturing process is divided into two: 1, sintered diamond cutting discs: two points and hot-cold sintering sintering, pressing and sintering. 2, welding diamond cutting discs: two minutes of high-frequency welding and laser welding, high frequency welding temperature molten media through the head and the substrate are welded together by laser welding high-temperature laser beam will head contact with the substrate edge melts to form a metallurgical bond ??? 3. Diamond cutting discs: the head is attached to the base powder by electroplating method for cutting a sheet, Tianyi abrasive, cutting sheet provided by the Weifang Production Co. Tianyi abrasive. Cutting, Tianyi abrasive, cutting film production is Abrasives Co., Ltd.
