- Q: Why is the drill angle 118 degrees?
- HSS high speed steel drill bit: vertex angle is generally 118 degrees, sometimes greater than 130 degrees, HM carbide drill bit: vertex angle is generally 140 degrees; straight groove drilling is often 130 degrees, three edge drill is generally 150 degrees.
- Q: What drill does 42CrMo use to drill better?
- Carbon structural steel 42CrMo, with ordinary high-speed steel drill bits can be larger, with 60 holes, first with a drill hole, then the reamer drill bottom hole expanding.
- Q: How do you get yellow on the surface of the drill bit?
- The Yellow above the drill is not baked. It is a kind of coating which is evaporated and ionized by the titanium metal in the high temperature and high vacuum environment. At the same time, the coating is added to the metal surface after the reaction of the reaction gas. It is also called PVD coating.
- Q: 8mm iron expansion bolts with few drilling drill mm?
- It's a gross mistake to say 8 mm punching. As with a hammer smashed bolt can not. Strictly speaking, 12 mm bit should be used, but if the expansion bolt is not standard, you need to drill 10 millimeters, then twist the hole, it is best to use caliper to measure the diameter of the bolt and then decide
- Q: What's the difference between a deep hole drill and an ordinary bit?
- Ordinary drills are of relatively low hardness, impact resistance and wear resistance. The drilling accuracy, drilling speed and the drilling speed of conventional drills can not be compared with those of deep hole drilling.
- Q: Do you have any special drill for aluminum alloy?
- Twist drill grinding points need to pay attention to, first of all to ensure that the correct grinding angle. The two main cutting edge length and angle to symmetry, there is a formula: drill blade surface on the wheel. The drill shaft out of the front, left oblique angle. From the back edge grinding angle, swing up and down the tail don't tilt.If necessary, the cross edge can be repaired, and the trimming edge and the chip separation groove can be polished, and the blade should be cooled during the grinding process to avoid the edge annealing.
- Q: What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?
- The cost of the blade is relatively low, and the cost of cemented carbide blade is about 3% of the total processing cost,CBN blades are reinforced and guided, and they can prevent edges from chipping when machining materials with a hardness of more than 50RC.CBN blades make up 5-6%, so using cheap blades is a wrong way to save money. The use of advanced materials in the short term can recover the investment, and the waste rate is very low.
- Q: 304 stainless steel material generally what kind of drill material processing?
- Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
- Q: Why not hammer drill iron
- Motor protection device: comprehensive in use will inevitably have hard granular access to a machine (especially on the machine to work on drilling, such as drilling on the top wall), if there is no certain motor protection, rotating at high speed can easily be hard break or scratch enameled wire, eventually lead to the motor failure.5, 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 motor commutator, prolong the use life6, hammer drill double function: both the impact hammer, electric drill and penetration.
- Q: How do we drill a tile with a thickness of 5mm glazed, without a glass bit, only the impact bit? What's up? The brick is attached to the wall!
- If the tiles under not hollow cement, Tim is very full, can not grasp, if you should buy a special tile bit, namely triangular bits, it does not produce tremor phenomenon, easy positioning, cut resistance, opening soon, there are the ordinary chuck used on an electric drill to need to pay attention to slow speed in particular, is just beginning to open and slow speed when wearing. When in use, add coolant (not too much, but keep adding water). Drilling can be done on hard materials such as glass, stone and tile. 3MM-16MM have, but don't drill edge or side (away from 2 cm above tile seam), or to use the glass or diamond drill hole, is used to watch the speed slower (800-1000 revolutions per minute or so), continue to water cooling (don't need too much, but continue to add water) non dry drilling! High temperature friction, causing serious wear and tear, affecting the use effect!
