- Q: How do you drill a bit?
- A bit, including a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E). The orientation of the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
- Q: How do the drills grind?
- A formula: "edge on the wheel surface." This is the first step between the bit and the grinding wheel, and it is often the students who have not cut the edges of the blade, so they start sharpening on the grinding wheel. It must be hard to wear. The blade here
- 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: What method should we pay attention to when drilling small holes and long holes in plain drills?
- When the bit is drilling the deep hole, the peak angle of the drill must be flattened so that it can drain the cuttings. In addition, when drilling, it is necessary to raise the drill bit and clean the drill bits in time, so as to prevent the bit from being squeezed by the chip, so that the drill bit is broken. Don't add too much coolant when drilling deep holes.
- Q: What is a two center drill? What's the function?
- There are two drill centers, one for passing through the casing and one for enlarging the diameterHey！ I can't help it! Specializing in the production of mine accessories. Cutter, cutter, drill bits, diamond mine anchor drill, cross wind drill, spiral drill pipe, anchor, mining machinery fittings, rock drilling tools
- Q: Angle action and characteristics of standard twist drill
- The helix angle, the beta helix angle, is the angle between the most outer spiral line of the drill bit spiral groove and the axis of the drill bit. Since the lead of each point in the spiral groove is the same, the helix angle of the drill bit at different diameters is different, the helix angle at the outside diameter is the largest, and the closer the central helix angle is, the smaller the helix angle is. Increasing the helix angle increases the rake angle, which is beneficial to chip removal, but the drill bit stiffness decreases. The spiral angle of a standard twist drill is 18 to 38 degrees. For smaller diameter bit, the spiral angle should be smaller to ensure the rigidity of the drill bit.
- Q: I want to be in the stainless steel frame and fixed drill a few screws, with what bit and screw
- However, Hui Shang building materials network reminds you that when drilling, the speed should be lower, the back angle of the drill to be larger, and side grinding, grinding narrow, in order to reduce the side blade and hole wall friction. In addition, when drilling, it is best to add some vinegar to the drill bit, so it will be easier to drill holes.
- Q: How big is the 6 bit that the worker says?
- Usually they don't talk about units, they just say the data, he says, 6 of the drill, that's the drill with a diameter of 6mm, that's right
- Q: The whole alloy drill often breaks
- Drilling with carbide drills is the most afraid of bit feed instability, vibration and pulsation, which is the most likely to break the drill bit. If the drilling is not guaranteed, the cemented carbide bit can be used instead. The body of this drill is made of tool steel material, but only hard alloy material is inserted in the cutting part. The drill will not break the drill even when it is drilling.
- Q: Which material, gb1436 and 6542, has a good drill?
- 6542 is a high speed tool steel.Most of the drilling holes for high-speed processing, so the majority of small drill bit is 6542, this is the must choose.Most drilling holes are low speed processing, and the manufacturing cost is considered, so most of them do not use 6542.GB1436 "straight shank twist drill", this is a standard, is a straight shank twist drill specifications, size, not material.
