To investigate wear characteristics of tunnel boring machine (TBM) disc cutter rings interacting with types of rock, a range of wear tests were performed on a TBM cutter test rig, and laboratory-scale disc cutters were used in the experiments. The mass loss, vertical load, temperature field, wear mechanism and change rule of cutter tip for the disc cutter rings were obtained during the tests. The results indicate that the rock types and properties of rock exhibit great influences on the cutter wear. The variation of the weight loss testing with different types of rock is partially explained by the discrepancies of vertical load, cutting temperature, and the transition of wear mechanisms. In addition, the test results show that the wear characteristics of cutter rings are mainly affected by uniaxial compressive strength (UCS) rather than equivalent quartz content (EQC) for types of rock. This study will benefit the design of cutter rings with enhanced wear resistance.

为了研究隧道掘进机（TBM）圆盘铣刀环与岩石类型相互作用的磨损特性，在TBM圆盘铣刀试验台上进行了一系列磨损测试，并在实验中使用了实验室规模的圆盘铣刀。在试验过程中，获得了圆盘刀环的质量损失，垂直载荷，温度场，磨损机理和刀尖的变化规律。结果表明，岩石的类型和性质对刀具的磨损有很大的影响。不同类型岩石的失重测试的变化部分由垂直载荷，切割温度和磨损机理的变化来解释。此外，测试结果表明，刀具环的磨损特性主要受单轴抗压强度（UCS）的影响，而不是受岩石类型的等效石英含量（EQC）的影响。这项研究将有益于具有增强的耐磨性的刀环的设计。
