Cutting rollers for tunnel boring machines (TBM)

Microtunnelling is an innovative drilling method. It enables the trenchless, economical and environmentally friendly laying of pipelines regardless of the soil conditions. When using this method, only a small starting and finishing pit is required. The company Mika GmbH is specialized in the development, production and rehabilitation of Cutting Rollers for Tunneltrade.

Mining tools for tunnel construction "Made in Germany

Precision cutting tools for cutting pipes in micro tunnelling are the core business of the manufacturer Mika Bohrtechnik. A well boring machine with a cutting roller is installed for pipe advancing in rocky subsoil. Depending on the substrate, a roller cutter for the boring machine can be made of different materials. Roller cutters are available as cutting rollers for rocky ground and for mixed ground. A cutting roller can be partially machined, hardened or forged. Cutting Rollers also differ in stroke, cutting roll type, assembly, performance and dimensions. Dimensions for Cutting Rollers are given in millimeters and in inches. Manufacturer Mika exclusively offers Cutting Rollers made in Germany.

Different variants of Boring Machine Cutting Tools for special foundation engineering

For pipe jacking in rock, a rock cutting roller is mounted on the Boring Machine. Mika Bohrtechnik offers the perfect roller cutter for every geological condition. Information about the geology on site forms the basis for the development of the perfectly suitable customer-specific cutting roller for horizontal drilling technology. To ensure that the cutting roller optimally meets the requirements of the soil and the customer, the specialists for Cutting Rollers analyse geological surveys. In addition to Cutting Rollers, the manufacturer Mika offers peeling knives, roller cutters in all sizes, double insert boring bars, reamers and drill bits for all brand name boring machines for microtunnel technology.

Cutting is the term used to describe the cuttings that are transported into the drilling channel with the drilling fluid. By forming deposits, cutting reduces the diameter of the borehole, which may increase friction. Therefore, a good removal from the cutting is to be aimed at during the drilling process.
