- Q: The difference between steel teeth and inserted cone bit
- The bits in the underground work after a certain time, drag bit blade diameter became small, short, blunt, the rock breaking ability becomes weak, slow progress; roller bit tooth wear due to erosion, bearing damage, will cause the cone roller rotation is not flexible or stuck, so that the torque increased, if not timely play that will happen cone off accident; diamond bit due to formation heterogeneity caused by PDC bit on the occurrence of crack, break, drop, also make slow drilling footage. In order to speed up the drilling of the whole well, the old bit must be replaced in time
- Q: How do you drill a bit?
- A bit, including a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E). The orientation of the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
- Q: What drill is used for machining holes with a diameter of 3mm?
- It is suitable for drilling when holes with smaller processing diameter and less than 4mm are used. Because the processing of small holes, requiring high spindle speed, while the drill bear a great torque.
- Q: How do you determine the speed of the drill? Is there any standard?
- Different diameter of the drill bit, drilling speed, diameter smaller, higher speed, otherwise low;
- Q: Why can't the tap be nitrided? Drill bits are available.
- Because the tap material is high speed steel, the cutting line speed is too low, coating cost performance is not high. So previous coatings were used less.
- Q: How big is the screw hole at the back of the torch chuck? Is it a rebound?
- If the chuck is to be assembled, stop the spindle from turning, and some have a rectangular edge that clamps the parallel edge with a thin, corresponding opening.
- Q: Twist drill 200mm deep bore, what does the drill grind?
- The students have learned the relevant knowledge of standard twist drills in the course of production, and can basically memorize the standard sharpening requirements of standard twist drills:The vertex angle is 118 + 2, 2?The posterior horn at the margin of the hole was 10 -14 degreesThe transverse edge angle is 50 degrees -55 degrees(two) the length of the main cutting edge and the two angles of the axis of the drill bit must be equalTwo main flank surfaces should be sharpened and polished.
- Q: What kind of drilling bit is good for stainless steel?
- 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.
- Q: 1.5 of the stainless steel plate to drill 1.2 holes, the drill has broken a lot of roots, what kind of material with a bit better? How much speed, how much feed?
- When drilling a stainless steel material, it is better to add some vinegar to the drill so that it will be easy to drill. Stainless steel drilling, the speed can not be high, high, easy to drill bit. 1.2mm hole, the speed hit 1000 rpm almost. In addition, the drilling of stainless steel, it is very hard to drill, the drill is not fast, and timely grinding, do not force to drill down, it will easily break the drill.
- Q: M2.5 hit the bottom teeth with much bit
- M2.5 is the diameter, you want to use this diameter to subtract the distance of the tooth, that is, the diameter of the drill. In the metric system, the distance of M2.5 is 0.45.
