- Q: New drills usually need sharpening before they can be used. Why?
- What you say does not exist, the new drill is not heavy grinding can be used; cutting edge is yes, the front angle is the drill bit of the spiral groove angle, it is impossible without the front angle, and the back angle is not 0 degrees, the peak angle is not big. It's only in the drilling that produces what I said before, so it's time to rub it again and use it again.
- Q: What drill is used for machining holes with a diameter of 3mm?
- At the same time, it is difficult to guarantee the absolute symmetry of the two main cutting edges because of the small bit. Generally, it is necessary to control the secondary angle of the blade edge at 6 degrees to 8 degrees. The speed is between 1000~1500, and the feed is low, otherwise the drill is easy to break or damage. The emulsion should be cooled during processing.
- Q: What are the weight specifications of the drill pile when the bridge pile foundation is constructed?
- Impact drilling in two main forms, one for earth or soft rock using tubular hammer, one for hard rock is solid hammer, the general hammer is about 4-5t, if you want to increase, you can hammer on the steel bar plus counterweight.
- Q: How to install expansion screw? How big is the screw? What size is it? Or what? How do you see the size?
- Expansion screws have models, usually M6, M8, M10, M12 and so on. M6 only refers to the diameter of the nut and screw. If drilling, the drill bit should be selected according to the diameter of the expanding part of the expansion tube. We usually use larger size drills.
- Q: What's the difference between a drill bit and a tap?
- You have a good sense of humor. Of course the drill bit is used for punching.
- Q: At present, the strongest oil drill bit, the deepest can drill how many meters?
- Oil and gas drilling is divided by depth, 4500-6000 meters belong to deep well, 6000-9000 meters belong to ultra deep well, more than 9000 meters belong to special deep well.
- Q: To do the M4 screw hole, what size holes must be drilled first?
- According to my experience in the industry, since you are an aluminum piece, you should use kerosene or kerosene and cutting fluid when you tap. This will make the tapping more smooth and protect the tap and thread. In addition, the general aluminum pieces should be steel wire screw, otherwise, the teeth are easily broken.
- Q: By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?
- The drilling depth - to determine the guiding edge and drilling parameters of the drill: shallow ordinary drill, a set of parameters, if more than 10 long deep hole diameter ratio, cooling the drill bit will choose to guide blade, and soon after the first slow step feed, with 2 sets of parameters, the other through hole, then reduce the parameters in the proposal through;
- Q: What do you mean by 5 times diameter drill?
- The length of the chip slot is 5 times the diameter of the drill bit.5 times a bit is the drill depth that can reach 5 times the diameter of the drill. For example, a drill with a diameter of 10 can process 50 deep holes.
- Q: What method should we pay attention to when drilling small holes and long holes in plain drills?
- When drilling a deep hole or a long hole, the workpiece must be fixed. Drill the hole with the center first, then drill with the bit so that the drill will not drill the hole when it is drilled.
