- Q: How do you get yellow on the surface of the drill bit?
- Coated cutting tools are in hard alloy high strength and toughness or high speed steel (HSS) on the body surface by vapor deposition method is coated with a thin layer of good abrasion resistance of refractory metal or non metal compounds (can also be applied in ceramics, superhard materials such as diamond and cubic boron nitride blade) obtained. The coating acts as a chemical barrier and thermal barrier, reducing the diffusion and chemical reaction between the tool and the workpiece, thereby reducing the wear of the crescent groove.
- Q: At present, the strongest oil drill bit, the deepest can drill how many meters?
- Oil well drilling machine is mainly used for exploration and exploitation of underground oil and gas resources. It is composed of derricks, winches, rotary tables, big hooks, overhead cranes, taps, drill pipes, drills and so on. The drilling depth is 2-15000 meters.
- Q: What is the maximum available drill bit for an electric drill with a maximum diameter of 10mm?
- 13mm, there's a three column handle, which is equivalent to reducing the diameter of the chuck and the direction of the drill is large.
- Q: Why can't the tap be nitrided? Drill bits are available.
- Tap can be treated by nitriding, often used in cast iron aluminum castings. The effect of nitriding is to increase hardness. Wearable ~!
- Q: What drills are used in tapping 304 stainless steel?
- Now on the market is generally a bit alloy steel material whole bit, although the materials are the same, but due to the processing technology, various brands of product quality disparity. Imported and domestic alloy drills are also very different. Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m) in the application of high performance drill and ordinary milling machine, the hardness and toughness of the ideal together. Take high quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35, thermal stability up to 1100 degrees celsius. After coating, the drill color is bluish gray. After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.
- Q: 14 what big expansion wire does the drill use?
- Sleeve type, is ordinary, cheap price, M10 D12, M12 D14, M16 D20, the biggest drawback is to put the bolt can be placed in fixed equipment, if equipment base fixed hole heavy equipment, then put the bolts in any case not put in equipment.
- Q: What is the cause of the drilling mud bit?
- Geological factors: the drilling for upper diagenetic ooze, easy to paste on the bit surface, bit balling caused by compaction after formation of shale; although diagenesis, but easy dispersion, the borehole mud or solid content increased, adsorbed on the surface of drill bit by bit balling; or the strata containing dispersed gypsum, resulting in mud pollution, harmful solid mud in difficult to remove, the probability of bit balling is increased; the formation of high permeability, under pressure, harmful solid phase adsorption within the wellbore and cuttings did not timely carry out the formation of thick mud cake, while tripping in PDC below the drill bit caused by the accumulation of bit balling.
- Q: How big is the smallest bit?
- The smallest bit: the diameter range of the blade 0.5-1.0mm.
- Q: The whole alloy drill often breaks
- 1, choose machinery with better mechanical performance to minimize the unevenness of bit feed.2, fixed firmly machined workpiece, minimize and avoid workpiece vibration, workpiece beating phenomenon.3, the processing of the feed should be stable, slow, slow, remember to act too hastily.4, if all aspects of the existence of factors, can not guarantee smooth drilling, you may wish to use carbide inserts bit. The body of this drill is made of tool steel, except that the cutting parts are inlaid with carbide inserts. The drill bit does not hurt even if there is a certain amount of vibration when drilling. It will not cause the bit to break.
- Q: What kind of steel do you need to drill?!
- A cemented carbide drill bit with an average size of 1 microns. This kind of drill not only has high hardness, but also improves the compressive and bending strength. In order to save the cost of many bits by welding handle structure, the original bit for the whole hard alloy drill, the back part of the handle adopts stainless steel, but the cost is greatly reduced due to the use of different materials and its dynamic concentricity is inferior to the whole hard alloy bit, especially in the aspect of small diameter.
