The design,installment and position of three kinds of cutter adapters used to machining welded steel tube's faces are introduced.

This paper introduced three designing methods of cutter adapters used on bevel pipe ends: (1)Formed cutter & Dual-face cutter (2)Floating beveling cutter & Dual-face cutter (3)Duak-beveling cutter & Trio-face cutter A detailed description about assembling and positioning the three cutter adapters is presented in the paper,as well as the analysis of their advantages and disadvantage

Principle and Maintenance of Cutterhead Control System of Shield Machine;

Three-dimensional Cutting Simulation by Cutterhead of Shield Machine Based on Parallel Computing;

As tunneling and cutting equipment of a shield machine,the cutterhead can excavate stratum,stabilize excavation face,mix soil slag, etc.

During the Xiao-song shield machine drills through the Pearl River which part belongs to Xiaoxin section works of Guangzhou Metro line 4, the cutting wheel of the shield machine has worn badly though the cutters are replaced continually, however, the geology below the river can t provide the conditions with repairing the worn cutting wheel.

This paper has analyzed the hydraulic system of the cutting wheel and screw conveyor in test tunneling machine, and the integration of the hydraulic system.

Designing and optimizing of the cutter of developing parallel link excavating shield driven by hydraulic cylinder;

Study on klingelnberg bevel gear interfere with the cutter in process;

Analysis and comparison were made of cutter types, support modes, torque, driving force and arrangement of jacks, spiral conveyor and slurry and foam feeder, to ensure selection of proper shield.
