- Q:What is the four hole five hole hammer
- Five: refers to the pit slot number is five at the handle of hammer drill hole, three key and two ball groove, used in the five pit on the hammer. This drill is usually used in the heavy hammer.
- Q:How big expansion screw does the 6mm bit have?
- Expansion screw generally refers to the metal expansion screws, expansion screws fixed, but the use of wedge slope to promote expansion, friction, grip force, to achieve fixed effect. One end of the screw is threaded, and the other has taper. Outside the bread (some tin pipe), iron cylinder (steel tube) has several half incision, put them together into the wall lay the hole, then the lock nut, the nut screw pull, pull cylinder taper iron, iron cylinder is open up, so tightly fixed on the wall, generally used for protection bar, awning, air conditioning and other fastening in the cement, bricks and other materials. But its fixed is not very reliable, if the load has a larger vibration, may be loose, so it is not recommended for the installation of ceiling fans.
- Q:What drill can be used to break through high strength stainless steel plates?
- Diamond bit, absolutely good, it depends on you do not have to use up
- Q:What is the material composition of the electric hammer drill?
- Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
- Q:What kind of steel do you need to drill?!
- Some use ion implantation technology to inject titanium, nitrogen and carbon into the substrate at a certain depth, which not only improves the hardness and strength, but also makes them move when the drill is regrinding. Also, a diamond film is formed at the top of the drill bit by physical means, which greatly improves the hardness and wear resistance of the drill bit. The hardness and strength of cemented carbide are not only related to the ratio of tungsten carbide to cobalt, but also to the particle of powder.
- Q:What's the difference between full mill and rolling twist drill?
- A word is not clear, the different processing technology, the high production cost of drilling grinding, rolling and drilling cost is relatively low, also has the gap, drill grinding durability is more than fifty percent higher than in the rolling, and workpiece cutting performance, drill to drill a lot, I was the production
- Q:What are the tools, drills, and any of the machine tools made of?
- High speed steel means containing more tungsten, chromium and aluminum alloy elements such as the tower of metalwork of steel, commonly known as steel or stainless steel.The machine is characterized by simple manufacture; high hardness (63 ~ 66HRC), wear resistance and heat resistance (about 600 - 660 C); have sufficient strength and toughness; have good craft; can bear greater impact; tool manufacturing complex shape, such as special lathe tool, milling cutter and drill, broach and gear cutter; but notIt can be used in high speed cutting. Grades and properties of commonly used high speed steel.The hardness of high speed steel after quenching is HRC63 ~ 67, and the red hard temperature is 550 ~ 600 DEG C, and the allowable cutting speed is 25 ~ 30m/min.The bending strength and impact toughness of high speed steel is high, can be cast, forging, welding, heat treatment and machining, has good grinding performance, the grinding quality is high, so it is used to manufacture complex shape of tools, such as drill, reamer, milling cutter, and also used for low speed machining tool and forming turning tool.Commonly used high-speed steel grades are W18Cr4V and W6Mo5Cr4V2 two.
- Q:How do you drill a sharpening bit?
- The blade is fixed against 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"The mouth" is the main cutting edge, and the "cut out" means the main cutting edge of the grinding part is in the horizontal position. "Wheel surface" refers to the surface of the grinding wheel. "By" means slowly moving closer. The drill cannot contact the grinding wheel at this time.
- Q:M3 threaded hole. The bottom should choose large diameter drill bit
- The bottom of the thread hole of the above M3 is the standard diameter of the drill bit made of ordinary materials. Of course, the actual production operation because the M3 screw mechanical properties of various materials is not the same as the processing of the material properties through appropriately adjusting, processing, such as M3 stainless steel threaded hole, must be to increase the diameter of the bottom hole processing, because the mechanical properties of stainless steel and ordinary materials are not the same. Stainless steel material hardness high, heat dissipation is poor, the reason of higher plastic, bottom diameter with a diameter of 2.7 bits. So in the actual operation, the operator should be through different material properties, adjust the threaded hole diameter of M3, so as to prepare for the next tapping.
- Q:What's the difference between a twist drill and an impact drill?
- A twist drill is a tool for cutting round holes in a workpiece by rotating it in a relatively fixed axis. It is named because of its shape of spiral groove. The spiral groove has 2 grooves, 3 grooves or more grooves, but the 2 groove is the most common. The twist drill can be held in manual, electric, hand-held drilling tools, or drilling machines, milling machines, lathes and even machining centers. Drill materials are generally high speed tool steel or carbide.
