- Q: What are the differences between a twist drill and a construction drill? Where are they used?
- A twist drill is usually a metal drill. Construction drilling is the impact of drilling, more for concrete, masonry and other drilling.
- Q: How many diamond grinding wheels should be used for an alloy bit?
- I don't know what machine you're grinding on. Generally 120 items are enough. My clients are 120
- Q: Hammer can play with an electric drill steel, can you
- The disadvantage is that the vibration is large and has a certain degree of damage to the surrounding structures. The steel bars in concrete structures can not be passed smoothly. They can not be too close to the building because of the scope of work.
- Q: What is the difference between steel and high-speed steel?
- High speed steel: all metal cutting is done with high carbon steel at once. This grade of steel shows high hardness, but tends to soften very quickly when heated. The addition of tungsten and chromium to the cutting steel makes it more resistant to heat when it is heated, thereby enabling a significant increase in cutting speed. These steels are called high speed steels. Other types of tool steels are less important for cutting purposes than this class. HRC66-69
- Q: What are the brands of homemade twist drills?
- Twist drills are made of many different materials, and different materials have different hardness. The angle or just ordinary relatively low hardness, so in theory, as long as the geometric angle of precise angle quasi good drill, only poor material life is low. Because of this, so many people like fraudulent use of materials, or connecting the handle with other materials, the head good. But now there is a process called roast yellow, this process after the connection part of the defect, a look at it.
- Q: How big is the drill bit for the 7mm hole?
- If 7 holes are machined, 6.9 bit holes are used, and 7 reaming holes are used to obtain the qualified holes
- Q: What size drills and taps are required for drilling M10's internal threads?
- Tap with M10*1 tap (not considered the accuracy of thread); if it is M10*0.75, use Phi 9.2 bit; tap with M10*0.75 tap (not considered the accuracy of the thread level).
- Q: What's the angle of a standard twist drill?
- The front angle is 2, and the front angle is the projection angle of the two main cutting edges on the plane parallel to them. The small front angle is easy to cut into the workpiece, the axial resistance is smaller, and the working length of the cutting edge is increased, and the nominal thickness of the cutting layer is reduced, which is beneficial to heat dissipation and to improve the durability of the cutting tool;
- Q: Method for processing coolant hole of internal cooling bit
- Tap is a single hole, in terms of high-speed steel, large caliber can be gun, drill or EDM to solve, small caliber, such as the outer diameter of 6 is difficult to solve. I heard the French company to provide timber Fuleikong can. Think of Germany's Cobalt collar, the British dormer, Japan's OSG, cold, this is all he has to provide materials.
- Q: Sharpening of drill angle when machining different materials
- For the sharpening of the drill, we should grind the drill at different angles according to the needs of the drilling. For example, a bit of drill bit drilled to a relatively hard material can grind larger (i.e. flat);
