- Q: 1.5mm iron plate, what drill can drill holes? You can drill?
- You can drill. You said the iron is generally low carbon cold-rolled sheet, about 300W of the maximum 6mm hole drill can drill. Maximum drilling torque 1N*M, drilling force 60~70KG, feed 0.1mm/r. So, 1.5 of the sheet metal, and then put on.Buy an electric drill to see how many holes you need to drill, and the greater the drill hole, the greater the power of the drill. The largest electric drill can drill into the hole of 20mmThe drill is made of a high speed steel bit, and a little better. You can buy the carbide drillUsually referred to as "iron plate", is a kind of low-carbon carbon structural steel, yield strength low, high elongation, brand Q195, Q235 and so on. It has high plasticity and toughness. A no problem
- Q: What are the differences between a twist drill and a construction drill? Where are they used?
- Impact drills operate 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 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: Is there a standard for drilling errors due to machine tool shaking?
- There is no standard for the drill hole error due to machine tool shaking.
- Q: What bit is better for drilling 304 stainless steel?
- Alloy bit generally refers to the hard alloy bit, divided into integral, welded, indexable inserts and removable head. Generally the whole tungsten alloy drill bit materials, imported and domestic alloy bit is very different. Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m), will take the high-quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35 the thermal stability, up to 1100 degrees celsius. After coating, the drill color is bluish gray. After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.
- Q: What size drills are we going to use to drill the holes in the M7 and with the larger twist drills?
- The common thread M7 second series, not commonly used, the coarse thread pitch according to the national standard of 1mm, therefore, the bottom of the thread holes at the 6mm, actually should be: the bottom hole diameter of =7-1.06p, where p is the pitch, calculated 5.94mm, underport with 6mm drill bit, not too bad. After drilling, tap with M7 tap.
- Q: How big is the drill bit for the 7mm hole?
- If 7 holes are machined, 6.9 bit holes are used, and 7 reaming holes are used to obtain the qualified holes
