- Q: I want to buy an electric drill with requirement is about 3MM bit penetration with ordinary bowl to eat what to buy an electric drill to much power and strength
- Upstairs said good, the key in the drill bit. But the speed of the electric drill must be high, the line speed is fifty or sixty meters per second. The drill shall be ground into the negative rear angle, and no water can be added. No water can be added halfway. You can't stop over.
- Q: What is a square hole drill and can be machined square hole?
- A circular drill can only drill round holes at one time, so that it is necessary to use non-circular curves to perform the wonderful characteristics of a fixed width curve. Non circular curve of constant breadth in the simplest one is leelo triangle.
- Q: How to recognize the quality of twist drills?
- General twist drill, a variety of points. It seems to be divided into two major groups. One is pumping out the twist, one is full mill. Now there is a knife bar slotted on top with knife particles. Called fast drilling, this is the high-speed processing of relatively large holes, pumping out the twist drill hardness is not so good, slightly better edge. As long as the mother material is good, the grinding accuracy is high. Now many are using this, relatively speaking, the price is much more expensive.
- 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: What drill holes are used in stainless steel basins?
- Crazy, what do you want to do?. If the drill or two eyes, ordinary bits, slow speed can. If you drill it into a sieve, choose a high temperature resistant steel bit. To the hardware store to ask, buy a professional drill stainless steel twist drill, it can save effort point.
- Q: Bit grinding, hair and technical requirements
- There is now a knife grinding machine YN-01A+ drill grinding machine grinding twist drill on the market, SG fast drilling, DG long short blade edge deep hole drilling, in the processing of 3D within the hole, the ordinary twist drill into fast drilling, without positioning, direct drilling, hole position accuracy and the efficiency on the use of ultra fast; DG to the mill, if it is less than 10D or above according to the processing of materials and machine tools and other site by cutting and grinding method when less than 3D above 5D; worn by YN-01A+ zzm-a drill bit to meet the basic situation the essence of drill bit efficiency 2-3 times, the service life of the drill bit can provide 3-5 times; this machine operation is simple and fast, without experience in technology, one minute can grind a bit.
- 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: What method should we pay attention to when drilling small holes and long holes in plain drills?
- Coolant added a lot, although the cooling effect is good, but it will make drilling cuttings are not easy to row out. Just use a brush with a coolant, and when the drill is lifting the cuttings, brush some of the coolant on the drill. Each time the drill is drilled down, do not enter too much at once. Especially in the hole drilling more and more deep, but also frequently drill bits, cleaning up drilling chip.
- Q: Do you have any special drill for aluminum alloy?
- Aluminum alloy, copper, stainless steel, these materials are not high hardness, aluminum alloy, copper soft, frequent drilling process, it is easy to have cutting, there will be a lot of burrs, aluminum alloy special drill.
- 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.
