- Q: What's the difference between a twist drill and an impact drill?
- Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for drilling reinforced concrete.
- Q: How many diamond grinding wheels should be used for an alloy bit?
- If the hard alloy is generally 100 mesh coarse grinding, and then finishing 180, we have foreign customers dedicated to the electroplating grinding wheel are generally parallel to that, the two particle size. Plain drills and cutters use CBN wheels.
- Q: What is a square hole drill and can be machined square hole?
- You can drill through the square hole, but not once.
- 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: To do the M4 screw hole, what size holes must be drilled first?
- M4 pitch 0.7, the hole diameter of 3.4 (but also generally drill 3.2 aperture, mainly to see when tapping convenient), generally with twist drill (drill hole processing tool, from the solid material is the most widely used tool in machining tool)
- 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: 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: The whole alloy drill often breaks
- 1, choose machinery with better mechanical performance to minimize the unevenness of bit feed.2, fixed firmly machined workpiece, minimize and avoid workpiece vibration, workpiece beating phenomenon.3, the processing of the feed should be stable, slow, slow, remember to act too hastily.4, if all aspects of the existence of factors, can not guarantee smooth drilling, you may wish to use carbide inserts bit. The body of this drill is made of tool steel, except that the cutting parts are inlaid with carbide inserts. The drill bit does not hurt even if there is a certain amount of vibration when drilling. It will not cause the bit to break.
- Q: What causes the drill bit to break at the end of the hole?
- When the speed is low, the feed is too large.If the cutting resistance is greater than the twist strength of the drill, the bit can be broken when the speed is low.
- Q: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?
- Deviation angle of drill shaft." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the top angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the drill point size and the main cutting edge shape and cross blade edge angle. Often. One and two refers to the relative position of the drill before sharpening, and the two should take overall consideration, not to set aside the edge of the knife and ignore the angle of setting or to lay the oblique axis and ignore the blade. These errors are often present in actual operations. At this point, the drill is ready for contact with the wheel in place of the correct position.
