Selecting the appropriate disc cutter configuration is critical to ensuring stable penetration and reduced downtime in hard rock TBM projects.In granite and other high-abrasion formations, cutter ring material, heat treatment quality, and seal performance significantly influence service life. Engineering-based selection should consider:

Rock compressive strength

TBM thrust and torque parameters

Cutterhead layout configuration

Expected penetration rate

Qingyue's engineering team provides cutter selection analysis based on geological data and operational parameters, helping contractors optimize cutting efficiency and control replacement frequency.Continuous performance data accumulation from domestic and overseas projects enables ongoing structural refinement of cutter rings and load-bearing components.
