Henan power supply stone diamond CBN tools

Diamond tool during use, diamond tool often because many factors affected by wear and tear, and that at this point above our previous analysis, the processing tool has a certain influence on the diamond tool wear, today we have to analyze the workpiece and the Wear factors processing materials for diamond tool. First, since the load state of wear of the diamond tool with its closely related, and therefore the processing conditions have a significant impact wear.戴向国 analyzed the effects of process parameters on the wheel life when cutting engineering ceramic diamond grinding wheel that when other parameters constant cutting depth corresponding to each exist in an optimal wheel speed; when the cutting depth and wheel speed is constant, there is a The optimum feed rate of primary and secondary order of process parameters on the grinding wheel radial wear amount of influence as: wheel speed - Cutting depth - feed rate. Coordination tool wear and process parameters and process parameters between a great relationship, it is necessary to optimize the process parameters. ZJPei analyzed the situation during the refining of silicon, the following conclusions: When the wheel speed is 4350rpm, chuck speed of 590rpm, the grinding force increases, when a certain peak, back to a lower value, and Keep doing this cycle, indicating the wheel gradually becomes dull, when the grinding force reaches a certain value grains broken; when the wheel speed is 2175rpm, chuck speed of 40rpm, wheel broken at the grinding force is small. Therefore, the grinding force substantially constant and the wear rate. Second, different workpiece materials, fracture toughness, hardness etc. large difference, so the nature of the workpiece material also affects the diamond tool wear. It is when there are professionals with different stone diamond saw cutting tool wear and states: When cutting hard granite, the diamond saw the wear is mainly macro-cracking and falling grain, because the holding is not enough, cutting conditions bad when cutting softer granite, complete micro-crystalline and broken grains account for a large proportion, but still high proportion of grain loss, which wear cutting saw blade retention capacity. West Xu Peng said: properties and deformation mechanism of granite in different minerals are key determinants of the diamond failure mode. Quartz content is higher, the more severe diamond wear; if the content of feldspar significantly higher, the cutting process is relatively difficult to carry out; at the same cutting conditions, coarse grained granite, fine granularity than granite cleavage fracture is more likely to occur. http://www.shilijiaodao.com/ 34 5.13 Reamer http://www.shiligunlun.com/ 14 7.13 diamond wheel http://www.shilichedao.com/ 11 8.3 Tool
