Tunnel boring machine tools. The tunnel boring machine has gradually become popular in recent years in domestic subway construction projects, cross-river tunnels, railways, tunnels, and large hydropower projects as a fully mechanized rock and soil excavation equipment. The configuration of the cutter tools and the performance of the products directly affect the service life of the cutter head, cutting effect, excavation conditions, tunneling speed, and construction efficiency, making it a very important rock drilling tool product (see Figure 1).

The rock-breaking tools on the cutter head of the tunnel boring machine are also a type of mechanical cutting drilling tool. With the rapid growth trend of various types of tunnel boring machines in our country, the market for tools used in tunnel boring machines will also see significant development (see Figure 2).
