Problems solved by technology

[0003] The performance of the diamond grinding wheel mainly depends on the composition of the diamond abrasive and the bond, and the design of the diamond grinding wheel is based on the grinding processing method and the material and processing quality requirements of the workpiece to be processed. Only when the performance of the diamond grinding wheel and the grinding Only when the processing method is compatible with the processing material can a relatively ideal effect be obtained; and now most manufacturers directly use the diamond grinding wheel on the ordinary single-sided machine, double-sided machine and beveling machine to directly apply it to the fully automatic CNC glass four-sided grinding machine, when the processing speed reaches 8m / min, the edge of the glass will be chipped. The glass is also deformed
The diamond grinding wheel on the ordinary single-sided machine, double-sided machine and beveling machine is applied to the automatic CNC glass four-sided grinding machine with low grinding efficiency and short life. To fully reflect the performance of the fully automatic CNC glass four-sided grinding machine, only A grinding wheel suitable for the grinding method of the fully automatic CNC glass four-side edging machine can be developed

Abstract

The invention discloses a diamond grinding wheel for high-speed four-edge grinding and a manufacturing method of the diamond grinding wheel. The diamond grinding wheel comprises a base body and a work layer, and the work layer is composed of, by volume, 75 percent to 93 percent of bronze bond dedicated alloyed powder and seven percent to 25 percent of diamonds. Firstly, the diamonds are dumped into a grinding bowl, and liquid paraffin is added to be fully wetted with the diamonds. Then, the bronze bond dedicated alloyed powder is dumped for even mixing, and mixtures are obtained. The mixtures are dumped into an assembled mold, the mixtures are placed in a dual-body sintering furnace to be sintered after striking and prepressing, and mold unloading is carried out after sintering and cooling. An obtained semi-finished product is ground and finished, and the diamond grinding wheel for high-speed four-edge grinding is obtained. The diamond grinding wheel for high-speed four-edge grinding has the advantages of being stable in performance, sharp in grinding, high in efficiency, low in cost and the like, and the machining requirement that sheet glass machined by imported and domestic high-speed four-edge grinding machine tools is 30 m / min to the maximum degree can be fully met.
