- Q:Why can't the tap be nitrided? Drill bits are available.
- The surface of the drill seems to be a titanium nitride coating, not nitrided.
- Q:Carbide drills and high speed steel drills, which are suitable for working stainless steel?
- Easy sticking knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts.
- Q:How can the gun drill be unloaded?
- You have to decide what is the drill or hammer. The drill is to use special wrench with teeth, no special wrench, can this tooth clamping cone drill, with a metal rod inserted in the cone under Kong Zhong, one hand holding forceps, a metal stick, twist, it fell. Hammer, seize the clamp bit press back at the same time, on the other hand, pull forward, will be able to take off.
- Q:What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?
- Machining method of high hardness workpieceHigh hardness steel, hard powder metal, super heat resistant alloy and bimetallic material are more and more widely used in industry.
- Q:What causes the drill bit to break at the end of the hole?
- The cutting edge angle is not proper, and the iron chip blockage causes the resistance to increase.1) and the principle of uniform, when the edge angle is not appropriate, the drill operation must not only overcome the cutting resistance, but also overcome iron friction and pore wall blocking resistance, resistance and greater than two fold twist drill strength, also can cause the drill bit break.
- 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:Is it OK to drill holes on tiles with an ordinary bit? Will the tiles crack?
- Not a bit of the problem, mainly tile problems, good quality tiles are not easy to crack.
- Q:With what drilling steel
- Tungsten steel (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:M6 screws should drill big holes
- Metric screw M6 applies m5de, which is also related to the thickness of your material. Two, if you turn the standard, you should give slightly larger, not too much, you can put ten screws
- Q:What's the difference between an impact drill and an ordinary electric drill?
- Professional on the wall, concrete, stone top drilling, and multifunctional electric hammer, adjusted to the proper position with appropriate drill can replace the ordinary electric drill, electric use. The hammer is using bottom motor drives two sets of gear structure, a realization of it drill, and another one is to drive the piston, a hydraulic engine stroke, resulting in a strong impact force, along with drilling results. Strength can split rocks into gold.
