Cantilever-type roadheader as rock cutting machine has mature technology, excellent quality, adapts to minimum cross-section of about 6.5 square meter.
As rock cutting machine, waterjet cutting machine is used for directly cutting transport pipelines, oil tanks and other flammable and combustible articles, or cooperating with public security or fire control department for emergently coping with oil leakage accidents or traffic accidents of transport vehicles of flammable and combustible articles by undertaking emergent cutting operations.
Cutting-bit as rock cutting machine 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.
Now they use this roadheader for nearly three years. After overhauling now it is in good condition for further use. This equipments has stable performance and good operation and the footage is stable.
The use of this equipments has stable performance and good operation, it is stable for footage and get good appreciation from our customers. By using, cutting, shipping, the effects on the work surface is better.
Now the process is under construction and the equipments is debugged successfully and the operation has reached stability, the footage is stable and the user can use more and more easily.
