The Development of the TBM Disc Cutter Test Device for Cutting Rock

In order to study the disc cutter cutting performance and the cutters combination feature and to explore a new high-efficiency breaking method in hard rock environment, a new multifunction disc cutter test device plan is established and carried out based on the analysis of relevant research and test equipment at home and abroad. The test device consists of a vertical loading mechanism, a longitudinal cutting mechanism, a shock loading mechanism and a control system, etc. It can be used to conduct not only single test such as cutting under static load, fragmentation under impact load, indentation test under static load and wear test of the disc cutter, but also combined cutting test under impact and static load. At last, granite was cut on this test device by the TBM disc cutter under different loads, the results are desirable and show that the test machine can provide the relevant test conditions and the basic data for the design of the TBM disc cutter.
