cutter bits as drilling machine for tunnel construction

Cutting-bit is a kind of wearable part in roadway excavation machinery, roadheaders. It is the main tool for cutting rock and mineral. Common raw material from the majority of domestic and imported suppliers is : 42Cr, 35CrMnSi and other steel, hardness of up to 40-45HRC, impact toughness of not less than 49J / cm2. Now with the ONE BELT ONE ROAD construction of China along the way, the ROADHEADER machinery has been used more and more in the roadway works apart from the mines due to its better flexibility and lower working cost. Moreover, the cutting-bits at the same time also need to withstand high periodic compressive stress, shear stress and impact load, which requires the cutter body parts to have very good impact resistance and withstand wear and tear.

hydraulic nuts as drilling machine for tunnel construction

The Hydraulic Nut is a permanent fixture, replacing the conventional nut and retaining the high bolt load and extension in small space envelopes where there may not be sufficient space to use tensioners. The nut can be retrofitted to existing plant and is a simple and accurate solution to mechanical jointing problems.
