The TBM disc cutters
TBM disc cutters: the importance of quality
Breaking the hardest rock requires exceptional quality
Tunnel Boring Machines (TBMs) are designed to operate in various geological conditions, from hard rock to mixed soils. The success of a tunneling project depends largely on the efficiency and durability of the cutting tools used. TBM cutting tools play a fundamental role in ensuring high excavation speed, optimal performance, and minimal wear, thereby reducing machine downtime and operational costs.
TBMs employ a range of cutting tools, including scrapers, rippers, and cutters, selected according to geological conditions to optimize material removal and minimize maintenance requirements. Among these tools, TBM cutters — particularly disc cutters — are critical components and are specially manufactured for rock crushing in the most difficult ground conditions.
Made of high-strength materials, such as alloy steels, these components are designed to withstand extreme pressures and ensure a long operating life. A TBM disc cutter is engineered for precision and durability, ensuring that every aspect of the excavation process is optimized.
The RingX ® from AB Tunnelling are top-level TBM disc cutters designed to deliver maximum performance in every condition. Discover how these innovative solutions are revolutionizing the tunnelling sector!
Ringx ®, the state of the art in tbm disc cutters
TBM cutters are the tools that have the most demanding task among the mechanical elements that make up the excavation system: to attach the rock with maximum efficiency and guarantee over time the best performance in terms of wear resistance.
AB Tunnelling has long studied the problems of drilling and the causes of the deterioration of cutting tools (which shorten their life cycle), to optimize boring and tunnel construction, minimize machine downtime, and, consequently, significantly reduce costs.
The result was RingX ®, a truly unique, top-quality TBM disc cutter patented in 2021, setting a new industry standard.
Why choose RingX ® TBM cutters?
– Superior Alloy Composition – RingX ® have a steel alloy that is precisely balanced and enriched with chromium, molybdenum, vanadium, and carbon, making them superior in composition. This ensures exceptional hardness, toughness and wear resistance, even in high impact and high compression excavation environments.
– Innovative Cutter Geometry – The innovative geometry of our TBM cutters has been designed for maximum efficiency, both in terms of blade profile and lateral structure. This allows the cutter to distribute workloads more effectively, minimizing stress and extending the service life, even in heterogeneous geological conditions.
– Advanced Heat Treatment Process – The RingX ® TBM disc cutter is treated with a specialized heat treatment that includes high-temperature heating, ultra-fast cooling, and precise tempering. The prevention of deformation and breakage ensures that quality and mechanical properties are consistent across all production batches.
