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: What bits of percussion drills are made of?: Purpose: hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q: Can HSS drill bits be drilled into stainless steel?: Yes, but it's best to have cobalt high-speed steel bit, but it's better to use a carbide drill. High efficiency and cost performance. We can make stainless steel special drill.

Q: I'm going to drill 10.5 of the thread. How many holes do I have to drill before tapping? How big is the tap?: Drill 10.5 (should be M12) of the screw holes to drill 10.25mm hole and tapping, tapping with M12 tap.

Q: How does the CNC lathe drill center to detail?: That is, there are other tools on the lathe, such as cylindrical lathe tool, on the basis of other round turning tools, the outer surface of the cylinder to maintain XThe direction is constant, Z direction retract, then take a look at this knife, X direction of the mechanical coordinates of X1 (must be mechanical coordinates),The X value of the excircle tool you use to measure the caliper is X2 (diameter value), and the mechanical sitting of the drill bit in the center of the workpiece is calculatedStandard calculation method: X=X1-X2/2, and then the mechanical knife drill bit moving coordinate value in the way of using the handwheel, tool cutting tool number in direct input bit 0, and then click on the soft keyboard "measurement", so as to better.

Q: How big is the drill bit for the 7mm hole?: If the big point is OK, use 6.5 bit to drill a hole, and then use 7 bit reaming, we can get 7.0-7.1 hole, directly use 7 bit drilling, the hole error is the biggest. Hope to be helpful to you, please adopt.

Q: Twist drill 200mm deep bore, what does the drill grind?: A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but the grinding method is really good, and the method and the skill of grinding are well mastered. Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.

Q: How does an electric drill drill a hole in the 16mm with a 10mm drill bit?.: The first shot 10mm hole, and then pull out the 1/4 distance in the clockwise direction of reaming, turn around, and then pull out the 1/4 left until the drill wall, then try to put what if the expansion screw is not wide enough to continue with the previous method, until enough, almost feeling hammered into the turnbuckle screw do not pay attention to the problems.

Q: What's the angle of a standard twist drill?: It is divided into 135 degrees and 118 degrees135 degrees vertex angle is mainly used for more hard workpiece, this design is to improve the positioning of the drill bit accurate (because 135 degrees need to open the back angle), broken cutting fastThe drill with a top angle of 118 degrees is mainly used for soft materials. The purpose is to drill holes and feed quickly. That is to say, drilling speed is very fast

Q: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?: 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 stability of the consolidation of one or two of the formula, the drill can be gently contact for a relatively small amount of grinding wheel, grinding, grinding to observe the uniformity of the spark, to adjust the size of the pressure, and bit cooling. When the cooling start again after grinding, to continue to set the formula to the one or two position, it is often in the beginning is not easy to grasp, often can't help to correct change their positions.
