Using method of core drill bit

Non-core drill bit in use process, because of the existence of these problems, at the same time by the workpiece material, quality requirements, different situations such as restrictions on  core drill bits site, the technical measures adopted accordingly in order to change. 1) due to the  diameter  core drill bits bit of low strength, poor rigidity, easy to break, so the beginning of  core drill bits, the feed force should be light, prevent the  core drill bits bending and sliding, so as to ensure the correct position before cutting  core drill bits. Note that the strength of the hand and feel feeding, when the bit bouncing, let it have a buffer range, in order to prevent the bit broken, sometimes as long as the feed force is very . The feed force is too , manual feed is not easy to feel it, then in the feed mechanism is provided with a  heavy Tuo, by weighing feed purpose. 2) in the core drill bit process, the need to pay attention to the frequent  core core drill bit withdrawing, promptly filed a bit. Because of the  diameter  core drill bits work, chip groove is narrow, chip is not smooth, so we should timely return  core drill bits chip, annealing times and hole  core drill bits depth is proportional to, can also take the opportunity to enter the cooling liquid or cooling in air. 3) use high precision  core drill bits machine,  core drill bitsing machine for  diameter  core drill bits requirements spindle sensitivity and high rotation accuracy,  vibration, good rigidity, the spindle runout should be less than 0.005mm,  spring clamping with special  core drill bits bits, and not the  core drill bits chuck or three jaw chuck clamp  core drill bits. Using circlip clamp can make accurate and reliable positioning, uniform stress and can offset a portion of deflection error, improve the rotation precision  diamond core drill bit, but should never use emery cloth, paper bold  hss core drill bit  handle clamping.

Abrasion of core drill bits

If the inside diameter of the diamond core drill bits core has been clogged badly worn without timely to diamond core drill bits, diamond core drill bits inside diameter will seriously wear. Inner tube loose rope core, inner tube upper suspension failure, are easy to cause clogging and damage the diamond core drill bits cores inside diameter. Note that the core diamond core wood sds plus auger bit blockage often cause burning or sticking. Conclusion In short, the right to judge the working conditions in the diamond diamond core drill bits hole, and for some reason abnormal wear is analyzed on the basis of targeted measures taken in order to improve operations, improve technology to reduce production costs and promote diamond core electroplated core drill bit work to improve the economic and social benefits greater.

The development of core drill bit

Core drill bits or needs to be replaced at the end of the center core drill bits, you should clear the hole, the hole bottom residue Chuijin, then stop turning, the center of the arix core drill bit slowly move up move, the size of the lifting force to move the center of the core drill bits just to mention as appropriate, to enhance the height of the eccentric core drill bits back up contact with the front end of the casing shoe; then core drill bits a low speed reverse, while slowly lifting up the test center core drill bits. When the observed center core drill bits can smoothly upgrade, show eccentric core drill bit has collapsed, then the center core drill bits can enhance a conventional manner, until all proposed center core drill bits. When reversing core drill bits, care should be taken to prevent tripping core drill bit.

Sometimes due to excessive residual rock bottom slag hole, eccentric rotary core drill bits is part of rock slag death eccentric core drill bits folded card. When try to mention a few still does not work, should convey compressed air, re-core drill bits for cleaning, and DTH for a short work, and then re-center the core drill bits lifting operations.
DTH core drill bits pipe construction technology is an effective method for overcoming the complex formation core drill bits means difficult, eccentric core drill bits pipe with its unique structure, excellent performance for complex formation to provide core drill bits construction a reliable technical support. Applied to the construction of the electroplated core drill bit pipe with the specifications of the series has also been increasingly improved.

How to use core dirll bit

When the complex formations with pipe segmented dry core drill bit, core drill bits parameter selection should be based on a low-speed, low feed pressure, high wind speed on the return to the principle of operation of the construction process should hardness of rocks, loose formations depending on the extent of core drill bits , moisture and other factors control core drill bits speed, especially when core drill bits encountered large loose or fractured formations, in particular, to reduce the feed rate and feed pressure, repeated slag hole cleaning. In the specific construction operations should also pay attention to the following aspects:

⑴ should be checked before the next core drill bit hole DTH hammer, with the core drill bits pipe, casing and casing shoe is firmly connected to the eccentric core drill bits rotation is flexible, whether ventilation.

⑵ should be observed during core drill bits to follow up the case and the case sleeve pink hole row, every 0.3 to 0.4 meters core drill bits should be a strong blow hole ranked powder to keep the hole clean. When the blow hole, center core drill bits up Poppet distance should be strictly controlled in order to achieve a strong blow hole powder row limit, prohibit core drill bits process in a strong pull from the center of the Non-core drill bit.

How to maintain core drill bits

arix core drill bit is often used in modern construction industry to a class of hardware and tools, with the core drill bits bit, the home will be some small core drill bits installation is particularly simple, but the quality and stability of the core drill bits bit quality performance is determined to a certain extent its results, so in order to use the core drill bits during core drill bits by showing some more good results, then the use of the core drill bits process must pay attention to its maintenance, how to care for the core drill bits in the course? Xiao Bian Weapon look at it!
 1, when core drill bits steel, please ensure sufficient cooling capacity and the use of metal cutting fluid.

 2, a good core drill bits steel and rail gap can improve the accuracy of core drill bits and core drill bit life.

3, please ensure smooth and clean magnetic base and workpiece.
4, when the core drill bits sheet, to reinforce the workpiece when core drill bitsing large parts, please ensure stability of the workpiece.
5, at the beginning and end of the core drill bits, the feed rate should be reduced 1/3.
6, a large number of fine powder of the material occurs when diamond core drill bit, such as iron, copper, etc., can not use the coolant, and the use of compressed air to help chip removal.

Core drill bits Scope

Also known as hollow electroplated core drill bit, tool steel is mainly used for core drill bitsing and other products, with specialized hollow core drill bits core core drill bits machine on, with quick efficiency, low cost, core drill bits with a hard edge portion alloy, has a three-end teeth geometry, cutting light, steel core drill bits long life, dual Weldon shank interface, the bell rig.

Segmented Dry Core Drill Bit

The drill bit is used to cut through or blind holes drilled in the solid material, tool and hole reaming on the existing. Commonly used drills are mainly Hemp flowers arix core drill bit, flat drill, center drill, deep hole drilling and trepanning drill. Reaming drill and countersink drill though not in the solid material drilling, but the habit will also them in a bit of a class. Digging, bit rotate around the vertical shaft, and axially movable. The soil is in the cutting torque and axial force on the bit, extrusion and centrifugal effects of blade is damaged and ramming loose and broken formation, soil flow pressure to the pit wall, along the page elevator to the surface. When the diamond core drill bit into the pit wall barrier when, because of broken soil around the centrifugal force thrown into the pit, to complete the whole process of digging.
