Testing Study on Surface Grinding of Post-High-Temperature Granite

For hard, brittle and difficult-to-cut materials, the technology heating auxiliary grinding has a significant role in improving productivity and reducing costs. Using different thermal loads and different ways of cooling to load granite,we carried out surface grinding experiments. We tested and analyzed variation of the grinding force and specific grinding energy. The results showed that strengthening the thermal load continuously, the grinding force and specific grinding energy reduce. This phenomenon significantly improves grinding efficiency and reduces the wear of wheel. Studies have shown that the auxiliary heating has an important contribution to enhance the production capacity of the stone processing.
