- Q:How do you drill a drill?
- 2, drill clockwise in the same direction, drilling tail down about 10 degrees angle, sharpening;3, drill once rotated 30 degrees angle or slightly larger, pay attention not to sharpen all other cutting edge, grinding two or three times;The 4 supporting point does not change, and the drill rotates 180 degrees, with the same method sharpening all other cutting edges;5, after grinding, the drill will be vertical (to make it natural droop), and hold it in hand, check whether the grinding bit is symmetrical with its center line;In case of asymmetric grinding, the angle between the cross blade and the cutting edge should be 50 degrees --55 degrees;
- Q:New drills usually need sharpening before they can be used. Why?
- The back angle of the new drill is grinded by the drill mill, which is made of special grinding bit equipment, and the angle is very straight. There is no circular arc R transition. If directly used to drill, drill will produce vibration and beating, the hole will be multi prismatic. Therefore, the new drill is usually used to drill the drill bit again according to the drilling condition, to grind out the back angle of the arc transition and the proper vertex angle, so that the drill bit can be drilled steadily.
- Q:Sharpening of drill angle when machining different materials
- Generally, when drilling soft materials, the drill is best able to wear a bit of sharp, so that the drill bit centering, and drilling out of the hole size is not too bad. But if there is no special requirement, drilling with different angles can be used to drill different materials. In addition, the drill can be drilled at different angles on the same material as needed. For example, drilling on the same material, if the size of the hole requirements are relatively strict, the drill will have to sharpen a bit, so that the drill bit of centring is better, drilling out of the hole is relatively round. But if we drill deeper holes, it is better to wear them flat so that the bits are better and the chip is removed so that the cuttings in the deep hole can be smoothly discharged. In short, it is necessary to flexibly select different drilling bits according to the actual situation.
- Q:How much is an alloy drill bit?
- Depends on what size and brand and technical requirements you need. I have no specific answer to that. You want a specific request for me
- Q:To do the M4 screw hole, what size holes must be drilled first?
- According to my experience in the industry, since you are an aluminum piece, you should use kerosene or kerosene and cutting fluid when you tap. This will make the tapping more smooth and protect the tap and thread. In addition, the general aluminum pieces should be steel wire screw, otherwise, the teeth are easily broken.
- Q:The drill marked difference with hammer marks
- When the adjusting knob is pointing to the side of the tool is a hammer, impact drill function. The impact function used in wall drilling, drilling alone for wood, metal, and other drilling books
- Q:How to distinguish between electric hammer drill bit used
- Shape: only two general electric hammer drill: head and head! The tail is square square. The tail of the round head is round.. Round head is mainly used with light hammer, the tail has two slots. The square is mainly used for heavy hammer!Size: use caliper to measure the diameter of the alloy steel on the head.
- Q:For 25 bit is much with the expansion screw
- For 25 bit is much with expansion screws, fasteners consultant Yu Wenlong think for 25 bit M20 with expansion screws.
- 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 size drills and taps are required for drilling M10's internal threads?
- M10*1.5 (not considering tap tap for precision thread); if M10*1.25, with Phi 8.7 bit; M10*1.25 (without considering precision tap tap thread); if it is M10*1, with 9 bit;
