Qingyue supplies single and double disc cutters for pipe jacking and microtunnelling machines. Cutter diameter, spacing, overall width and mounting dimensions can be configured according to cutterhead drawings, cutter positions and geological conditions. These cutters are intended for rock and mixed-ground applications where reliable cutting performance and dimensional compatibility are required.
Single disc cutters use a single cutter ring configuration and are applied on pipe jacking and microtunnelling cutterheads for rock and mixed-ground excavation. Cutter diameter, overall width, bearing arrangement and mounting dimensions can be matched according to the cutterhead drawing, cutter position and available installation space. The final configuration should be selected based on geological conditions and required load capacity.

· Single cutter ring configuration
· Dimensions matched to cutterhead drawings
· Suitable for rock and mixed-ground applications
· Bearing and sealing system configured according to project requirements
Double disc cutters feature two cutter rings arranged at a specified spacing within one cutter assembly. They are used on pipe jacking and microtunnelling cutterheads where the cutter layout requires two cutting tracks within a compact installation space. Cutter diameter, ring spacing, overall width and mounting dimensions can be matched according to the cutterhead drawing. The final configuration should be determined based on cutter position, geological conditions and required load capacity.

· Two cutter rings with specified spacing
· Compact configuration for pipe jacking cutterheads
· Customized diameter, ring spacing and overall width
· Mounting dimensions matched to cutterhead drawing

Pipe jacking disc cutters can be configured according to the machine type, cutterhead layout, cutter position and geological conditions. Dimensional and component requirements are reviewed against the customer’s drawings to support installation compatibility and reliable cutter operation.
Drawing-Based Matching
Cutter diameter, overall width, mounting dimensions and installation interfaces can be matched according to the cutterhead or existing cutter drawings.
Cutter Configuration
Single or double disc cutter configurations are selected according to the cutter position, available installation space and project requirements. Cutter ring spacing is reviewed for double disc cutters.
Component Coordination
Cutter rings, cutter bodies, shafts, bearings and sealing systems are coordinated as a complete assembly based on the required dimensions and load rating.
Supply Options
Complete single and double disc cutter assemblies can be supplied with customized dimensions. Replacement components can also be reviewed according to the existing cutter design.
Please provide the cutterhead layout, existing cutter drawing, cutter position and geological information. Our technical team will review the required dimensions and cutter configuration.
