- Q: New drills usually need sharpening before they can be used. Why?
- Grinding the drill bit again, grinding the back angle of the arc transition and the proper vertex angle so that the drill can bore smoothly. No sanding is available, but there is no radian in the rear corner, which can cause vibration instability.
- Q: How do you determine the speed of the drill? Is there any standard?
- Large hole processing speed is not too fast, too fast, easy to make the head color (coke), resulting in turn annealing, eventually scrapped;Small rotor speed should be fast forward to the amount of slow, fast, easy to break, turn around, pay attention to crumbs.
- Q: How do you get yellow on the surface of the drill bit?
- Coated cutting tools are in hard alloy high strength and toughness or high speed steel (HSS) on the body surface by vapor deposition method is coated with a thin layer of good abrasion resistance of refractory metal or non metal compounds (can also be applied in ceramics, superhard materials such as diamond and cubic boron nitride blade) obtained. The coating acts as a chemical barrier and thermal barrier, reducing the diffusion and chemical reaction between the tool and the workpiece, thereby reducing the wear of the crescent groove.
- Q: What are the brands of homemade twist drills?
- You drill stainless steel, you can try the square King's kind of fully polished red box. Iron, ordinary steel plate with yellow box. Relatively speaking, the price will be good. If you're rich, buy an old job or go to work. In addition, foreign brands in addition to M42 material is indeed not domestic, the other are domestic manufacturers processing. It has many big clients in foreign trade. Of course, you can also choose some small manufacturers of products, good luck can also buy the same quality products. Twist drill is so, set angle is greater than the material. Because I used the system to bake yellow, the square king used to drill stainless steel drilled 30 holes, so recommend it. His whole grind should work better, and the price is much more expensive than that of huang.
- 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: What drill is best?
- The drill bits are of high speed steel, of which 439365 are cobalt and cobalt is the best
- Q: How big is the 6 bit that the worker says?
- The default length units for machining and mechanical drawing are millimeters,
- Q: The difference between left and right drills used to drill holes
- If the twist drill is said to be left-handed or right-handed, this is related to the direction of rotation of the spindle. Regular drilling machines use the right-hand bit; in some special cases, the main axis of the drilling machine rotates opposite, and the left-hand drill is required.
- Q: For 25 bit is much with the expansion screw
- Fastener consultant Yu Wenlong believes that their best related information, come online is always false, meet the random response, smatter, is simply false or deceptive directly mislead you, even hurt you. Light product quality is not qualified, serious person should be fined. Of course, the fastener consultant Yu Wenlong believes that if the strength of a fastener, please refer to your technical consultant, to grasp the direction of enterprise development, product positioning, customer orientation is a good choice.
- Q: How do you tell which materials are used in the test?
- The drill shall be selected according to the material properties of the material to be machined. For example, stainless steel uses cobalt cobalt drills. Use tungsten cobalt alloy bit when producing high heat when the bit is cutting
