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, the hardness of up to 40-45HRC, impact toughness of not less than 49J / cm2.
The pick is made up of a cutter body (cutter/shank) and a carbide cutter. In the actual working conditions, the biggest difficulty in the use of these cutting picks is the carbide tip and the cutting tool-to-body welding technology. Most common problems faced are due to low-quality welding technology, such as welding coming off, leading to the carbide head cutting away from the body, thus affecting the overall cutting and cutting effect and damaging the main machine. With the introduction of our company's welding process for "tungsten carbide and steel", the cutting-bit wear resistance has seen a qualitative leap and the use of our roadheaders which is equipped with high efficiency cutting parts is safer and long lasting and durable.
