Raise Boring Methods: Navigating the Depths with Chuangyuan

raise boring methods: Navigating the Depths with Chuangyuan

Unravel the mysteries of Raise boring methods with Chuangyuan as your guide. From pilot drilling to conventional raise boring and blind boring, understand the nuances of each method. Explore how Chuangyuan's reamers play a pivotal role in achieving raises up to 6 m in diameter and 1000 m in length, shaping ventilation shafts, ore passes, and more.

Chuangyuan RCC Cutters feature an internal pressure compensating device to protect

the seal from excessive lubrication pressure and heat. And a pre-loaded tapered roller bearing

provides maximum shock resistance.

Chuangyuan Magnum Cutters feature the strongest bearing in the industry, the longest cutting structure and more carbide than any other cutter.

Unveiling the raise boring cutter Features

Forged Strength: Cutter cones, the heart of our technology, undergo forging with high-quality alloy steel, ensuring resilience and wear resistance even in the harshest conditions.

Customizable Carbide Inserts: Elevate service life and penetration rates with carbide inserts carefully chosen from a diverse selection of shapes, sizes, and grades.

Strategic Carbide Arrangement: Carbides find their place in cones with varying rows, creating a harmonious match that produces tailored row spacing to suit the nuances of different rock formations.

Optimized Bearing Systems: Whether it's combined axial-radial roller bearings or tapered roller bearings, our Raise boring Cutter boasts enhanced operating loads, guaranteeing a consistently high penetration rate.

Sealing Excellence: A metal seal and a pressure-balanced device work in tandem, fortifying the cutter against lubricant leakage and the infiltration of foreign materials, resulting in extended bearing lifetimes.
