- Q:The difference between steel teeth and inserted cone bit
- The inserted three bit bit is a new kind of wear-resistant material with high strength and high toughness alloy tooth and steel tooth bit surface. It can increase the drilling speed of the bit while maintaining the high mechanical drilling speed of the steel tooth bit. Different specifications of cone bit, three cone bit, Jianghan rock bit, drilling wells with cone drill, oil cone bit, mine rock bit, geological rock bit, gas wells cone bit, PDC bit, diamond bit, imported composite drill, 5 wing PDC drill bit, 4 wing PDC drill bit, 8 blade PDC bit.
- Q:Angle action and characteristics of standard twist drill
- The front angle is 2, and the front angle is the projection angle of the two main cutting edges on the plane parallel to them. A small sharp angle easily cut workpiece, axial force is small, and the cutting edge length increases, cutting nominal thickness decreases, conducive to heat dissipation and improve tool life; if the front angle is too small, then the bit intensity of deformation increases, the torque is increased, the breakage of the drill bit. Therefore, a reasonable front angle should be sharpened according to the strength and hardness of the workpiece material. The front angle of the standard twist drill is 2 and phi is 118 degrees.
- Q:Sharpening of drill angle when machining different materials
- Generally, when drilling soft materials, the drill is best able to wear a bit of sharp, so that the drill bit centering, and drilling out of the hole size is not too bad. But if there is no special requirement, drilling with different angles can be used to drill different materials. In addition, the drill can be drilled at different angles on the same material as needed. For example, drilling on the same material, if the size of the hole requirements are relatively strict, the drill will have to sharpen a bit, so that the drill bit of centring is better, drilling out of the hole is relatively round. But if we drill deeper holes, it is better to wear them flat so that the bits are better and the chip is removed so that the cuttings in the deep hole can be smoothly discharged. In short, it is necessary to flexibly select different drilling bits according to the actual situation.
- Q:Why not hammer drill iron
- Positive function: can make use of a wider range of electric hammer drill, the form is mainly realized through switch or adjust the brush position, usually big tools will be used to adjust the brush position (rotating brush) to achieve the benefits of doing so is easy to operate, effectively inhibit the spark to protect the commutator, prolongs the service life of the motor6, hammer drill double function: both the impact hammer, electric drill and penetration.
- Q:How can we change an ordinary drill bit into stainless steel?
- With ordinary stainless steel drill bits to drill, speed down, such as 100, add a little vinegar when drilling well drilling. In two, the lowest drill about three hundred rpm, speed a little faster. It is better to drill on the vertical or rocker arm, and the speed can be adjusted lower.
- Q:Which material, gb1436 and 6542, has a good drill?
- 6542 refers to the content of various elements in this material. For example, 6542 is W (tungsten) content of about 6%, Mo content of 5%, Cr content of about 4%, V content of about 2%.
- Q:What do you use for drilling walls?
- You want to drill the wall can be used with drill impact drill bit iron. If you don't like the iron hammer can buy the drill bit, the difference between the head with Ukraine ladle head. The head with a shaped yellow color of that. You must push the drill to drill in and you too. Big words can not clamp any drill, below 8 may, if you drill is imported can hold 10mm. Do not go to buy a hammer that bit because it does not fit your electric drill.If you drill is also can be installed if the electric hammer drill, drill the domestic only below 8, imports 10.
- Q:What is the cause of the drilling mud bit?
- Engineering Technology: small displacement drilling, can not effectively cleaning the bottom and at the same time, the return speed of drill cuttings in the well, long residence time, adhered to the wall to form a thick mud cake, especially in the upper part of drilling speed is more serious; in soft rock strata, the drilling pressure is too large, or drilling stratum with the drill bit is formed on the surface of direct contact, causing bit balling; long open hole drill is not halfway through the cycle, from the mud cake wall scraping or cuttings are bit balling.
- Q:How do the new pros and cons drill the drill bit without the key?
- There are two ways to unload and unload manually:Methods: hand unloading drill drill handle on the ground, pine along the direction of the drill bit to find a hard thing with the hammer hit, the release, remember that it is right to bear left loose, otherwise it will be more and more tightly card.The method of using a card or key to pry it open:(1) card: the electric drill is lifted and the clasp is removed to remove the drill bit;(2) bevel key: remove the bit by pressing the key with an anti clockwise ring, then the drill ring can be taken out.
- Q:Bit grinding, hair and technical requirements
- A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but it is not an easy task to sharpen the grinding method and the skill well.Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.
