- Q: What drill heads are used to drill holes in diamond heads?
- The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.
- Q: How do the drills grind?
- The drill shaft is slanting out of the front angle.." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the vertex angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the top of the drillAngle size and main cutting edge shape and cross edge angle. To remind students to remember a commonly used 30 degrees, 60 degrees, 90 degrees triangular plate angle of 60 degrees, students easy to master. A formula and formula two refers to the relative position of the grinding beforeThe two should take overall consideration, and don't neglect to set the oblique angle in order to settle the edge of the blade, or ignore the edge of the blade in order to set the oblique axis. These errors are often present in actual operations. At this point the drill is in the correct position
- Q: What steel blade drill bit, hardness above 60
- A diamond bit is a drill bit for cutting edges. The drill bit is an integral bit, the whole drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, it is one of the three new drilling technologies in the world in 1980s. Field use shows that the diamond bit in the soft - hard strata drilling, have the advantages of high speed, more footage, long service life, stable operation, less accidents, downhole wellbore quality etc.. The diamond bit not only can be used for a long time, but also can be reused. The diamond bit recovered from the factory can be used almost as well as the diamond bit produced by the factory. It can save drilling cost in large amount.
- Q: 1 inches of steel plate, what drill can drill through?
- Mainly used in drilling machines, lathes, flashlights and other mechanical equipment for the processing of different diameter aperture. Generally speaking, twist drills are straight shank and taper shank twist drills. Straight shank drill: suitable for drilling diameter psi below 13.0mm small diameter, taper shank twist drill for aperture and torque big hole.
- Q: Do we need drill bit for cast steel drilling?
- Sometimes we need to drill a hole in the iron surface with a drill, but what kind of drill is used to drill the iron? Do you know the types and uses of the drill bit? In fact, there are many kinds of drill bits, mainly based on their different uses, which is what to drill and what kind of drill bits to use. In order to let you better understand the relevant knowledge of the drill, the following Xiaobian give you a brief introduction to the use of a variety of commonly used bits of it.
- Q: Drills, drills, heating drills, will they be annealed?
- When drilling cast iron, do not use or use 5% ~ 8% emulsion or kerosene. When drilling steel parts, use 3% ~ 7% emulsion. When deep hole machining or cutting speed is higher, feed amount should be large enough to supply enough cutting fluid to reduce the influence of thermal deformation on workpiece and improve the quality of machining.
- 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: What's the difference between a UC drill and an ST bit?
- UC bit is used for high quality drilling, drilling temperature is low, less nail head, slag, broken rate phenomenon. Because of its low loss ratio, the drilling torque resistance is reduced, which is beneficial to micro drilling and more than 6 layers of PCB boards.
- Q: What are the main points of drill grinding?
- Grind back from the edge of the blade. When the blade is in contact with the grinding wheel, it should be drawn back from the main cutting edge, that is, contact the grinding wheel from the edge of the drill bit and then slowly grind down the whole flank. Gently contact wheel bit penetration, advanced for less grinding, and observe the uniformity of discharge, timely adjustment of the size of the pressure on the hand, but also pay attention to the drill bit cooling, can not be allowed to wear too much, causing the edge to edge discoloration, annealing. When the blade temperature is high, the drill bit should be cooled in time.
- Q: Cobalt containing special stainless steel drill bit, 4mm angle, do not move?
- The characteristics of stainless steel is high toughness, easy to stick a knife. So the drill hardness is high, surface finish better than ordinary bits, the bit angle large (130--135 degrees). At the same time to the full amount of feed and cooling. More than 0.15mm as much as possible without cutting in cold hardened layer. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.
