- Q: How are the drills classified?
- The cutting part of flat drill is shovel shaped, simple in structure and low in manufacturing cost. The cutting fluid is easy to be introduced into the hole, but the performance of cutting and chip removal is poor. The structure of flat drill is composed of two types: integral type and assembled type. The integral type is mainly used for drilling 0.03 to 0.5 millimeters in diameter. The assembled flat drill blade can be changed, and can be internally cooled. It is mainly used for drilling large holes with a diameter of 25~500 millimeters.
- Q: I want to buy an electric drill with requirement is about 3MM bit penetration with ordinary bowl to eat what to buy an electric drill to much power and strength
- The key is to fight through the bowl bowl bit, because of high hardness, ordinary drill is not moving, you can drill glass to the hardware store to buy 3mm, the diamond, the price of two or three yuan 1. The electric drill does not need high-power, ordinary 6mm flashlight can drill, remember to add water when drilling, or the drill will be accelerated because of overheating wear.
- Q: What is a square hole drill and can be machined square hole?
- The three vertices of an equilateral triangle as the center, edge radius at the apex on the side arc, get leelo triangle. As it is easy to prove that the triangle leelo properties, its width is equal to the structural length of the equilateral triangle. The length of the triangle leelo width within the square rotates, each corner of the path traversed basically is a square.
- Q: Small bit drilling, drilling machine speed is fast or slow?
- The two cutting edges should be the same length, and the cutting edge is usually between 8~12 degrees. Do not cut the cutting edge even lower than the back angle, so that the drill can not be drilled. In addition, the drill bit should be slightly sharpened so that the axial resistance of the bit during drilling will be reduced, so that the drill can save a lot of effort when drilling down.
- Q: What kind of drill bits are used in glass drilling?
- Cemented carbide bit is a kind of crushing load which depends on the drilling pressure and self rotation to break the rock.
- Q: Bit grinding, hair and technical requirements
- A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but it is not an easy task to sharpen the grinding method and the skill well.Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.
- Q: The basic angle of twist drill
- The back angle of the selected point on the main cutting edge of the twist angle alpha Om is expressed by the feed back angle alpha Om in the point column section. The column section is the point m of the main cutting edge, a line parallel to the axis of the drill, and the cylindrical surface formed by the rotation of the line around the center of the bit. The alpha Om changes along the main cutting edge, and the closer to the center, the greater the alpha Om. The back angle of the outer edge of the twist drill is usually 8 to 10 degrees, and the back angle of the transverse blade is 20 to 25 degrees. This can compensate for the influence of the angle of the main cutting edge on the actual working angle of the main cutting edge due to the axial feed motion of the bit, and can adapt to the change of the front angle.
- Q: What kind of drill is used on the stainless steel countertop?
- Stainless steel cabinet table drilling, stainless steel table need to prepare two kinds of drilling tools, a cutting stainless steel, the other is a layer of wood cutting stainless steel, stainless steel and wood cutting are used in cutting machine, electric drill is indispensable, hollow wood also used 3 cm diameter hole.
- Q: What drill is used for punching aluminum parts?
- There are aluminum alloy bit, select M42, M35 or 6542 bit.
- Q: How do the front and back angles of the drill change? How does it affect drilling?
- The front angle of the drill is the angle of the spiral groove of the drill. It is generally unchanged. After the drill angle should change according to the situation of the processing hole; for example, when drilling, the drill bit at the outer edge of the general angle generally between 8~14 degrees, if you want to draw it by fossa, orifice chamfering drill, drill angle will be smaller, the cutting edge of the drill will be down, like this helps maintain a steady state of the drill bit, rowed out nest and chamfer to smooth, does not produce the phenomenon of polygon.
