- Q: How do we calculate the length of a drill for a bored pile drill?
- There are two main types of drilling rigs: rotary drilling machine and impact drilling machine. The bit of rotary drill is divided into three kinds of scraper drill: suitable for quicksand and silt layer. Only the diameter and weight limit, no length limit cone drill: suitable for soft stone and hard soil. There is no length limited hob drill: suitable for hard rock layers. There are weight limit and hob arrangement, hardness requirements above, there is no drill length requirements. Impact drill: it is to use the weight of the drill to squeeze the soil into the hole, and the hole of the rock is also to use the bit itself to destroy the rock structure surface into holes. Only the weight on bit (according to the requirements of classification of rock hardness determine bit weight, diameter of 2-2.5 meters in the drill hole, the weight of at least 10 tons; 1.5-2 meters, bit weight of about 5 tons, 1.5 meters below 3 tons. For impact drilling, the length of the drill has a certain requirement, usually 1.8-2.5 meters high. Because the longer the drill bit, the stronger the impact drilling guidance function, the smaller the possibility of partial hole, hammer and hammer, the higher the standard of drilling. There are no rules and regulations, and you can succeed by experience.
- Q: What drill is used for machining holes with a diameter of 3mm?
- For the steel parts which require fine matching, it is recommended to drill holes with a twist hole smaller than 3mm and then drill with a 3mm bit to ensure the accuracy of the hole. As for plastic, cardboard or copper material, the aperture will be retracted. The drill bits which are slightly larger than the diameter of 0.10mm are generally used. If the machining requirements are strict, it is better to drill rough first. For example: first drill with 2.5mm bit, and then use 3mm bit reaming, so that you can guarantee the accuracy of aperture.
- Q: Bit grinding, hair and technical requirements
- Factory general grinding drill bit is to drill, drill into the general R type, N type, in fact, a total of four grinding twist drill can drill point: X type, R type, S type, N type, in fact, the little bit into these kinds of significance, we all know the drill bit what is not worth the money, make money on it is the efficiency of above treatment can only guarantee the basic meaning of the drill grinding drill bit, and to want to drill efficiency, to the point of efforts to drill bit is related to efficiency.
- Q: What drill holes are used in stainless steel basins?
- Crazy, what do you want to do?. If the drill or two eyes, ordinary bits, slow speed can. If you drill it into a sieve, choose a high temperature resistant steel bit. To the hardware store to ask, buy a professional drill stainless steel twist drill, it can save effort point.
- Q: How to install expansion screw? How big is the screw? What size is it? Or what? How do you see the size?
- M6, for example, uses a drill with a diameter of 8, so that the expansion part of the expansion screw is able to penetrate the wall.
- Q: Tap is M14-H2, drill with big bit
- The tap is M14-H2 and can be punched with a drill with a diameter of 12.The threaded hole diameter can be determined by the formula:The nominal diameter of the screw - thread pitch = threaded hole diameter
- Q: What is countersunk drill, flat head drill?
- Countersunk drill: it is a well formed drill bit that is basically used for machining countersunk headsA drill bit used to hide six square screws
- Q: By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?
- Drill bit, drill out of the hole than the drill diameter, because drilling cuttings will increase the extrusion aperture; at the same time, for the convenience of a chip it is necessary to improve bit will increase; if the concentricity is not good, it will increase more.
- Q: How can the 1 millimeter drill be worn?
- The "cutting edge" here is the main cutting edge, and students often turn the top and bottom of the mill into "up and down" when they are grinding. The workers who have been working for more than ten years have been working for more than ten years." This action is also important in the sharpening of the drill, and confidence determines power. When drilling. To master the methods, repeatedly "less grinding" test drilling and the appropriate grinding on the horizontal edge, chip is normal, this is very important, must let students stand in automatic hand grinder, is reading books on the knowledge, otherwise it will make the blade blunt, more understanding. The common standard twist drills only have two main flank surfaces, a grinding edge, a transverse edge, an oblique angle, and two main cutting lengths. In a stable consolidation formula, grinding twist drill is also a lot of bad. Students will find that sharpening a certified standard twist drill is not difficult and much more analytical. To remind students to remember a commonly used piece of 30 degrees." This is the slow grinding of the entire flank from the edge of the bit. A formula and formula two refers to the relative position of the grinding before, to adjust the size of the pressure. You can use a large angle bit and another small angle drill students in the test bench drill drill, the drill bit in drilling process of quick cutting, students can quickly grasp the right edge of the twist drill grinding method, 60 degree students, easy to master. It is easy to dissipate heat and grind. After mastering the methods and techniques, but after sharpening, you must ensure the vertex angle
- 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.
