Rotary Rock Bit Working Principle
Rotary Rock Bit consists of a bit body with three moveable conical rollers equipped with cemented carbide inserts. The idea is the crush the rock by rolling the inserts against the rock with appropriate rotation speed and feed force. Three types of cemented carbide inserts are used for roller type bits being Chisel, Conical, and Hemispherical. Carbide inserts are distributed over the three rollers in such a manner that the entire bottom of the hole is worked on when the drill bit is rotated. Roller bits for hard and abrasive rock generally have spherical cemented carbide inserts closely spaced. Roller bits for softer rock may have the chisel and conical carbide teeth or quality milled steel teeth as the cutters. A roller bit will utilize nozzles from which the compressed air escapes to lift the cuttings from the bottom of the hole.
Quality Control
In manufacturing, each process goes through an extensive and painstaking testing ,
quality control is a process that ensures customers receive products free from defects and meet their needs.
1, Raw material selection:To make a good drill bit, it is necessary to select the best material and gatekeeping the quality of the material. We purchase the high-quality steel and strictly control the material composition and size, it main includes the detection of the shape, diameter, reamed diameter, length composition, and flaw of the raw material, Tungsten Carbide and Grease are also the best raw materials on the market.Besides, we marked every different piece of materials before transferred to the warehouse.
2, In strict accordance with the ISO9001 international standards for production.
Carefully control every step of the production, complete each of the production process,
the production process is including blanking, forging, rough turning, heat treatment,fine turning, quenching, assembling, welding, painting, then storage.
Each working process was full inspected, after the qualification, then move to next working process, which to ensure the 100% qualified rate.
3, Sampling observation, numbered, packing and arrange the shipment.
