Question 2: What kind of drill is used to hit aluminum alloy? Under normal circumstances, you can buy an ordinary drill bit that is not used to drill wood. If you use self-tapping screws, you can buy a 3.2 bit.
Question 3: What kind of drill should be used to process aluminum alloy? Aluminum alloy can be drilled with high-speed steel drill or cemented carbide drill.
1) is 40% narrower than the common drill bit, thus reducing the friction heat generated between the hole and the drill bit in the cutting process, preventing the chip accumulation tumor caused by excessive heat from sticking to the drill bit edge, and fully ensuring the quality and accuracy of the hole.
2) electroplating. It is a low-friction coating, and its purpose is to improve the chip removal ability, which is the key to success. The main advantage is that it has the characteristic of "non-adhesion", which is a very important problem to solve many aluminum alloy materials processing. It not only improves the chip removal ability, but also improves the technical problems that were difficult to solve in the previous drilling processing of aluminum alloy materials.
Question 4: What kind of drill is used for aluminum alloy? Ordinary twist drills will do.
Question 5: How to punch aluminum alloy? There are two kinds.
1. Punch holes with a hand drill
Step 2 punch holes with a special machine
Question 6: What kind of drill is used to punch aluminum parts? High speed steel or alloy will do.
Question 7: What kind of drill is used for punching 7075 aluminum alloy sheet? Tungsten steel drill bit.
Question 8: Why does aluminum stick to the drill bit 1 when drilling? This is because a lot of heat will be generated when drilling, and the melting point of aluminum is relatively low, so the molten aluminum will adhere to the drill bit, so it will stick to it. You can slow down the drilling speed and give it a cooling time.
2 Aluminum parts are as follows:
Question 9: The drill bit is a cutting tool for drilling, usually made of high-speed steel, and the working part is hardened to 62 ~ 65 HRC by heat treatment. An ordinary electric drill consists of a handle, a drill neck and a working part. 1. Handle: it is the clamping part of the drill bit and plays the role of transmitting power. There are two types of handles: straight handles and tapered handles. The transmission torque of the straight shank is small, and it is generally used for drills with a diameter less than 12mm. Tapered shank can transmit large torque (mainly the flat tail part of the shank), and it is used in drills with a diameter greater than12 mm. Neck: it is used to retract the tool when grinding the drill with a grinding wheel, and the diameter of the drill is generally engraved on the neck. 3. Working part: including guiding part and cutting part. The guide part has two long and narrow linear sidebands (edges, that is, auxiliary cutting edges) and spiral grooves. The role of the blade is to guide the drill bit and smooth the hole wall; Two symmetrical spiral grooves are used for chip removal and conveying cutting fluid (cooling fluid). See the wall chart and physical object for the structure of the cutting part. It has two main chip edges and a handle edge. The angle between the edges of two main chips is usually 1 18 2, which is called the vertex angle. The existence of the cross blade increases the axial force of filing.
Question 10: Is there a special drill for aluminum alloy? In fact, the hardness of aluminum alloy, copper and stainless steel is not high, and aluminum alloy and copper are relatively soft, so it is easy to have cutting lumps and many burrs when drilling frequently. It is best to choose some aluminum alloy special drills. When drilling with different materials, the angle of the main cutting edge of the drill will be different. For aluminum, it is best to choose the cutting angle of 120- 135 degrees, and the feed rate should not be too high, but lower appropriately. If you know the material, you'd better choose M42, M35 or only 6542. The inferior bit won't work after drilling for several times. Bit is divided into roller drill and full grinding drill. Full grinding drilling is 30% more expensive than roller drilling, but the effect is more than twice as good. It's a bit long. To sum up, the best material is full grinding process. Which brand is easy to use, you can check Baidu, Alibaba, Taobao and Soso.
