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

1.    Cutter cones are forged with high quality alloy steel and heat-treated to high strength and wear resistance.

2.    Carbide inserts can be selected from a wide range of shapes, sizes and carbide grades to improve service life and penetration rate.

3.    Carbides are inserted in cones with different number of rows. The match of cutters with different rows carbides produces different row spacing to suit different rock formations.

4.    Combined axial-radial roller bearings or tapered roller bearings improve cutter operating loads, so the Raise Borer has a high penetration rate.

5.    The metal seal and pressure balanced device are utilized to improve sealing ability, prevent leakage of lubricant and ingress of foreign materials, and the cutter bearings have longer lifetimes.

6.    raise boring cutters can be easily mounted on the Saddles and positioned in Raise Boring Head in certain patterns with different row spacing for different formations.

7.    Chuangyuan raise boring cutters can be interchanged with SANDVIK and ATLAS COPCO raise boring cutters.
