- Q: Relationship between bit diameter and rotation speed
- If the bit is drilled at a low velocity, the drilling efficiency will be low due to the low line speed, and the drill bit will be easily broken due to the small size and the small strength of the drill bit. But because the bit in drilling, large diameter, high speed, line speed will be very high, the bit will be very easy to damage on sticky steel drill.
- Q: How to polish drill bit
- Grinding twist drill is the front edge of grinding, we do mechanical processing, the new twist drill must be polished, and then used. A mill can also grind, but it must be worn by those who can grind it. Percussive drilling and percussion drills are necessary for drilling. Twist drills for metal.
- Q: Why can't the tap be nitrided? Drill bits are available.
- Many imported taps are coated now. In addition to TiN, there are TiCN, TiAlN.
- Q: Deep hole refers to the diameter of drill bits more than times, called deep hole
- In machining, the hole with a hole ratio greater than 6 is usually called a deep hole. In deep hole drilling, it is difficult to get rid of heat and chip, and it is easy to bend and vibrate because of the poor rigidity of the drill rod. Cooling and cooling systems are usually used to solve cooling and chip removal problems. The classification of deep hole drilling is divided into two types according to chip arrangement: chip and chip. There are 3 kinds of chip removal drill, deep hole flat drill and deep hole twist drill. The internal chip removal is divided into BTA deep hole drilling, jet drilling and DF deep hole drilling.
- Q: What's the difference between an impact drill and an ordinary electric drill?
- An electric drill is a drilling machine that uses electricity as power. Is the power tools in the conventional products, but also the largest demand for power tools products. The electric drill is only available in the form of rotation, especially for drilling on materials that require little force, such as cork, metal, brick, tile, etc.. Just rely on the electric motor drives the drive gear to increase the strength of the drill bit rotation, do scraping in metal, wood and other forms of perforated material.
- Q: 304 stainless steel material generally what kind of drill material processing?
- Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
- Q: Why not hammer drill iron
- Electric hammer drill (electric hammer drill), is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill the reciprocating motion of the hammer. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
- Q: What kind of steel do you need to drill?!
- Drills are usually made of cemented carbide. The so-called carbide is based on tungsten carbide powder as a matrix, cobalt powder as binder, by compression and sintering. Usually containing tungsten carbide 94%, cobalt containing 6%. Because of its high hardness, very wear-resistant, has a certain strength, suitable for high-speed cutting. But the poor toughness, very brittle, in order to improve the performance of the hard alloy, with some hard carbide titanium carbide substrate in chemical vapor deposition of a layer of 5 to 7 microns (TIC) or titanium nitride (TIN), which has higher hardness.
- Q: What is the four hole five hole hammer
- Actually, what's the difference?:1: four pit is now the longest on the market with better match. Five of the pits will not fit the drill bit.2: the five pit is usually large with a hammer, more than 38, because the big hammer torque, relatively the five pit stress structure more reasonable.
- 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.
