- 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 measures can be taken to prevent the bit from breaking?
- I. to drill through, reduce the pressure. Slow down. Two. Drill the bit into a group
- Q: How big are the 8 bits that have worked up?
- If 8mm's expansion pipe uses a drill with a diameter of 8mm, if it is a 8mm expansion screw, use a drill with a diameter of 12mm.
- Q: How do you drill a sharpening bit?
- By the back edge grinding behind. This is the slow grinding of the entire flank from the edge of the bit. It is easy to dissipate heat and grind. Based on the formula one or two to consolidate stability, this bit can be gentlyContact grinding wheel, a small amount of grinding, grinding, to observe the uniformity of the spark, to adjust the size of the pressure, and pay attention to the cooling of the drill. When the cooling start again after grinding, to set the position of the one or two formula,This is often difficult to master in the beginning, often involuntarily change the correctness of its position.Formula four: "the next swing tail don't tilt." This action is also very important during the sharpening of the drill, and the students often change the "up and down" into "up and down" in the process of grinding so that the other main blade of the drill is destroyed. withThe tail of the drill can not be raised above the horizontal center line of the grinding wheel, otherwise it will cause the edge to be dull and can not be cut.
- Q: Why can an electric drill pinch the drill so tightly?
- There are three teeth scattered drill chuck, the teeth are retractable, with different thickness of the drill bit used to hold, in the roots of teeth (in the rotating disc, invisible), a spin silk, when rotating clockwise, wire like screw the teeth out, caught the drill bit, otherwise return to loosen the drill bit.
- Q: Deep hole refers to the diameter of drill bits more than times, called deep hole
- In machining, the hole with a hole ratio greater than 6 is usually called a deep hole. In deep hole drilling, it is difficult to get rid of heat and chip, and it is easy to bend and vibrate because of the poor rigidity of the drill rod. Cooling and cooling systems are usually used to solve cooling and chip removal problems. The classification of deep hole drilling is divided into two types according to chip arrangement: chip and chip. There are 3 kinds of chip removal drill, deep hole flat drill and deep hole twist drill. The internal chip removal is divided into BTA deep hole drilling, jet drilling and DF deep hole drilling.
- Q: What size drills and taps are required for drilling M10's internal threads?
- Tap with M10*1 tap (not considered the accuracy of thread); if it is M10*0.75, use Phi 9.2 bit; tap with M10*0.75 tap (not considered the accuracy of the thread level).
- Q: Specification of plastic expansion plug and collocation of drill bits
- General use of drilling bit is slightly smaller than the expansion plug specifications, with 3.8 4 mm drill bit expansion plug can. If is the same specifications for concrete especially hard objects, if a bit drilling specifications, pulling the hammer a little shake.
- Q: When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
- Medium and low strength alloy steel, cast iron and other easily processed materials: D=d1-P, in which D1 is thread nominal diameter (big diameter), and P is thread pitch. In the case of M10x1.5, hole size D=10-1.5=8.5.
- Q: What bit is hard, not easy to wear and punch?
- The drill is worn and can be grinded by a bit. We are using the Muller's drill and grinding machine. The effect of grinding the drill bit is very good.
