Diamond Drill Core Bit suppliers
The diamond core drill bit may be laser welded, which has the advantages of being simple to automate and having high production efficiency. It is a crucial area for uniqueness and innovation in diamond tool design. The laser welding technology was created with "uniform design" in mind, with a focus on the qualities that more diamond core drill bit specifications, higher accuracy, and poor welding. Uniform design software and a wealth of experience were provided as the experiment's technological parameters. The experiments reveal that when the welding speed is 1600 mm/min and the welding power is 2000 N/mm2, the welding seam is smooth, the flexural strength is higher than the European Designing Standard for the same product, and it is superior than other welding processes in dependability, safety, and stabilization.
Instructions:
1.After determining the drilling depth, select the required number and type of drill bits according to the structure and rock formation characteristics of the drill hole, and use them alternately according to the size of the drill bits;
2.Before the drill bit goes down the hole, clean up the residual core in the drill hole;
3.Optional circlip;
4.Choose a hole reamer that matches the drill bit;
5.Align the drill bit with the reamer to the drill hole. After the drill bit goes down the hole, turn on the pump to release water when the drill bit is 0.3-0.5 meters away from the bottom of the hole, and slowly lower the drill bit, and then clamp it when the drill bit is 0.2 meters away from the bottom of the hole. Chuck, light pressure and slow rotation, initial grinding for 10-15 minutes, grinding with the bottom of the hole, that is, the drilling operation.
6.It is always easier to start drilling with a spot drill. An electronic switch allows drilling at low speeds to safely introduce the bit into the material (5-10mm). Once engaged with the material, the centering device (drill bit) can be removed from the machine and drilling at full speed can begin.
Wet drilling
Concrete and natural (hard) stone must be wet drilled.
Ensure adequate water flow. There must be enough water to flush all residue out of the grooves. Cores with a diameter of 100 mm may require up to 5 l/min of water supply. If using a pressurized water container, make sure it provides the required amount.
Start hole guides and drills help with accurate starting and steering. These can also be used with catchment facilities. If neither a starter hole guide nor a drill is available, use a wood formwork to ensure you start drilling in the correct location.
When using a drill, make sure to:
The drilling machine is installed firmly;
The feed control is engaged and the rig is not moving under its own weight;
The stand is securely installed.
Improperly secured drills can cause core bit jamming and bit breakage.
Dry drilling
Dry coring should only be done on brickwork and soft lime or soft sandstone.
Vacuum up the dust. Rock and masonry dust is harmful. We strongly recommend that you also wear a face covering. Take the proper type of vacuum and also have ample suction. The high volume of suction air provides the added benefit of cooling the core drill body and, free of dust, runs more freely. Moving the coring drill back slightly from time to time during coring will make dust removal more effective. Make sure not to tilt the core bit when doing this, as this will greatly reduce its lifespan.
Use the solid guide inserted into the coring bit until a starting groove about 5 mm deep is cut. Then remove the pilot bit, otherwise it will start to overheat and become an unnecessary defect. Alternatively, you can use a separate hammer drill to make the pilot holes without removing the pilot from the coring bit.
How do we solve user problems?
Issue: Short lifespan of diamond core drill bits requiring frequent replacements.
Solution: Our factory has optimized the material selection and manufacturing process to improve the lifespan of diamond core drill bits. By utilizing high-quality diamond particles and wear-resistant alloys as blade materials, we have increased the overall durability. Additionally, we have enhanced the blade structure and connection methods to strengthen the drill bits, resulting in a 20% average lifespan improvement. Our diamond core drill bits now offer an extended usage lifespan, increasing from an average of 200 meters to 240 meters per drill bit. This reduction in replacement frequency enhances work efficiency and reduces maintenance costs.
Issue: Inconsistent performance and susceptibility to breakage of diamond core drill bits.
Solution: Our factory has implemented technical improvements to address these concerns. We have optimized the blade structure to enhance durability and minimize the risk of breakage. Furthermore, we have refined the geometric shape and cutting angles of the blades to ensure a more uniform cutting speed. As a result, users have experienced a 50% decrease in reported breakage issues and a 40% reduction in uneven cutting speeds. These enhancements significantly enhance the stability and consistency of our diamond core drill bits.
Issue: Poor drilling quality, such as uneven borehole walls and inaccurate cuttings.
Solution: To tackle this issue, our factory emphasizes stringent quality control and testing procedures. We utilize high-precision machining equipment and advanced measurement tools to ensure that the drill bits meet the required dimensional and geometric specifications. These improvements have led to a 60% decrease in uneven borehole walls and a 45% reduction in inaccuracies during the cutting process. Users now benefit from higher-quality boreholes, minimizing the need for repairs and adjustments, thus increasing construction efficiency.
