Product Overview
Tri-cone drilling bit is mainly used in large open-pit mining operations, such as open-pit coal mine, copper mine, molybdenum mine, iron ore mine and other non-ferrous metal mine. Tri-cone drilling bits are used on rotary drills, with a proven reputation of high performance and low cost. We have adopted a flexible production system with the incorporation of CNC machining centers, being its core component. The production line consists of manufacturing equipment such as forging, heat-treatment, CNC machining centers, along with advanced inspection equipment. The tri-cone drilling bits range from 6 3/4" to 13 3/4” in size, and the production line is capable of customized design manufacturing for different size and series of drill bits to meet our customer' s requirements.
Basic Structure Of Tri-Cone Drill Bit
Tri-cone drill bits consists of a bearing structure, cutting structure, shirttail and lug enhancement structures, flow channel system, and a thread connections.
The bearing structure consists of lug bearing, cone bearing, seal ring (sealed bearing), main rollers, minor rollers, locking bearing balls, axle thrust plate, and recess thrust plate. It can be categorized into air cooled open drilling bearing or sealed rolling bearing.
