19 inch Single Disc Cutter For Cutter Head Tunnel Boring Machine
The single disc cutter is installed near the edge of the front of the cutter head. It is mostly used to crush hard rock with high uniaxial compressive strength, and is a key component of breaking rock in tunneling. The product has good stability and reliability, and there will be no abnormal phenomena such as seal failure, eccentric wear, cutter ring breakage, cutter ring comes out of the hub (cutter ring falls off), bearing damage, stop collar breaks or falls off, severe wear of cutter hub and retainers, etc. We are responsible for the process technology, quality and related services of the products to ensure the overall quality of the products.

TBM Disc Cutter Features
1. Disc cutter manufacturing and processing: Through the advanced CNC machine tool to ensure the consistency of the size of the hob parts; combined with strict specifications of the assembly process to ensure the torque of the cutter, the torque is adjusted within an appropriate range, so that it can be well adapted to the surrounding rock geology, and to help solve the hob uneven wear in different formations.
2. Disc cutter sealing system: The sealing system of our disc cutter adopts the world famous brand metal sealing system. The twisting of the rubber ring during cutter assembly may cause the air leakage of the cutter, and this hidden danger is difficult to check out. We assembled the disc cutter through special technology to correct the phenomenon of the rubber ring twisting and eliminate the hidden leakage of the metal seal,and it ensures the sealing reliability of the disc cutter.
3. Disc cutter bearing system: Using heavy-duty tapered roller bearings made by world-renowned brands, which can withstand both radial and axial joint bearing HH series heavy-duty roller bearings.
