Tianying's IADC5 ** Series Mining Drilling Bits Application
Soft to Medium-Soft Formation
Application: For use in less abrasive softer formations with compressive strength ranging up to 140 Mpa, such as shales, limestones, carbonates and most metamorphic formations.
Cutting structure: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.
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.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.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.Sampling observation, numbered, packing and arrange the shipment.
Common fault analysis of Tricone bits
| Common fault | Fault description | Method |
| Early wear of the shirttail | Abrasive formations, bent drill rod, seriously worn stabilizer and insufficient air for drilling rate attained etc, are all the causes which result in premature shirttail wear. In this case, the configuration of cones is good and the amount of inserts wear is small. Shairttail wear can also allow the big roller bearings to fall out resulting in bit failure. | The designer should strength the shirttail with certain measures to increase the wear-resistance capacity of shirttails. |
| Early wear and loose movement of the bearing | Excessive weight on bit, insufficent air to clean the hole and/or cool the bearing, leads to bearings overheating due to improper cooling and poor cuttings removal can shorten the service life of bit bearing. | Reduce bit pressure and increase air pressure |
| Cutting structure failure | Excessive WOB or Rotation speed; Wrong bit selection; Cuttings blowing in bad conditions caused repeating crushing. | Correctly select operating parameters and rotary types for specific working conditions |
What is Mining Drill Bit?
1. Mining drill bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock.
2. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center.
3. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air.
4. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
Advantage:
1. Strictly select the material to ensure the reliable quality. Bad steel and tungsten carbide inserts won't be used.
2. Strictly act according to the ISO9001 standard, and control by full-scale inspection.
3. Sales and support people are highly trained in the latest rock drilling technology and can offer you expert advice on what products will best fit a specific end use application.
