In this way, the service life of the tri-cone bit can be prolonged and the working rate of the drilling can be improved. The tooth surface of the steel tooth bit is welded with a new type of material, which improves the life of the cutting tooth of the bit while maintaining the high mechanical drilling speed of the steel tooth bit. It can increase the drilling rate and reduce the cost of use. Wheels and multi-cone drill bits. It saves time and effort in drilling and exploration practice. 　　

The roller cone bit is more commonly used in petroleum drilling Forstner Bits factory and geological drilling. When drilling thin plates, reinforce the workpiece. The tapered design also has a significant effect on improving the stability of the drill bit., you can use compressed air to help chip removal without using coolant. The steel ball locks the cone to adapt to high speed.

When the tool is drilling steel parts, please ensure sufficient cooling and use metal cutting fluid. For materials with a large amount of fine powder during drilling, such as cast iron, cast copper, etc., you can use compressed air to help chip removal without using coolant.

When drilling large workpieces, please ensure that the workpiece is stable. Increasing the rate of cutting the rock formation can make the bit more bite. Especially after the emergence of jet roller cone bits and long nozzle roller cone bits, the drilling speed of roller cone bits has greatly increased, which is a major revolution in its development history. At the beginning and end of drilling, the feed rate should be reduced by 1/3. 　　

The tri-cone bit can accumulate the power to crush high-hardness rocks during high-speed rotation, which greatly increases the drilling speed. It saves time and effort in drilling and exploration practice. Please clean up the iron filings wound on the drill body in time to ensure smooth chip removal.

Someone can crush a part of the rock at the bottom of the well, and at the same time, use the shearing action of the sliding belt of the cones to cut the missing teeth. The three-tooth tri-cone drill bit is composed of more than 20 parts and components such as cutting structure, bearing structure, locking element, oil storage and sealing device, nozzle device, etc.

Threaded tricone bit; The number of wheels can be divided into single cone, two cones, three cones and multi-tooth tricone bits.. In the petroleum, exploration and various drilling industries, the toothed tri-cone bit is an indispensable and important part. When the cones roll at the bottom of the well, the teeth on the cones sequentially impact and press into the formation. When the cones are rotating at the bottom of the well, the teeth on the cones hit and press up to the sky in sequence.

The composite sheet can sharpen itself in the process of the task,Metal drill bits Manufacturers that is, after being worn, its front edge will still be blunt. The matrix drill bit is sintered with tungsten carbide powder, brazed on the tungsten carbide matrix with an artificial polycrystalline diamond composite sheet, and gauged with natural diamond. It reduces the cost of drilling for the drilling industry. 　　

There are two types of drill bits: steel body and carcass. The rock breaking method of the drill bit is mainly plowing for soft formations, and shearing for hard formations.

In those two night classes, general diamond drill bits are suitable for formations with relatively low abrasiveness, harder ground, and complex ground; Especially after the emergence of radial tricone bits and long nozzle tricone bits, the drilling speed of tricone bits has increased greatly, which is a serious problem in the history of the development of tricone bits. Rock, so that all rocks at the bottom of the well are broken, and the wellbore can be extended. This has prompted some drilling industries to have a lot of interest in second-hand tricone bits

During the drilling process, you must carefully operate, evenly feed the drill, and do not pressurize to start the turntable. When it is invalid, the drilling is decisively tripped and processed according to the eye-drawing procedure. The downhole conditions are normal, the wellbore is unobstructed, and the drill bit can go down to the bottom of the well smoothly; the drill bit should be lightly pressed and slowly rotated to reach the bottom of the well smoothly. 

After drilling, when the drill bit is a single root from the bottom of the well, the pump should Hollow Mortising Chisel Bits Manufacturers be opened to wash the well. The basic conditions for the drill bit to enter the well are: a. Cone drill bit press the nozzle into the water eye hole by hand or wooden stick

During the drilling process, if there is resistance and no hard pressure, according to different conditions in the well, the water hole on the top of the pump is opened at the right time, and the hole is intermittently drawn with a small displacement. , Record the use parameters of the drill in detail. Use a special up-and-down tool for loading and unloading PDC drill bits, and the inside and out of the drill bit should be properly clamped.

If there is a phenomenon of jerky drilling downhole, the drill bit should be checked out in time.. The roller cone bit should be 'run-in' for about 1 hour, and then drill according to the design requirements; the PDC bit should be lightly pressed and slowly rotated at the bottom of the well 'shape' 1-2 meters, so that the bottom of the well is consistent with the bit . Then drill according to the design parameters.
