- Q: Do we need drill bit for cast steel drilling?
- The drill material is usually made of high speed tool steel or carbide, and high speed steel is often used in the factory. When drilling, it will be added coolant according to the different materials and rotating speed.
- Q: Small bit drilling, drilling machine speed is fast or slow?
- The two cutting edges should be the same length, and the cutting edge is usually between 8~12 degrees. Do not cut the cutting edge even lower than the back angle, so that the drill can not be drilled. In addition, the drill bit should be slightly sharpened so that the axial resistance of the bit during drilling will be reduced, so that the drill can save a lot of effort when drilling down.
- 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: The basic angle of 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. A small sharp angle easily cut workpiece, axial force is small, and the cutting edge length increases, cutting nominal thickness decreases, conducive to heat dissipation and improve tool life; if the front angle is too small, then the bit intensity of deformation increases, the torque is increased, the breakage of the drill bit. Therefore, a reasonable front angle should be sharpened according to the strength and hardness of the workpiece material. The front angle of the standard twist drill is 2 and phi is 118 degrees
- Q: What drills are used in tapping 304 stainless steel?
- Asked to sell drill bit, stainless steel drill bit, usually they know. Our company uses cobalt cobalt bit. It's very durable and works wellIf there's anything better, I don't know.
- Q: Deep hole refers to the diameter of drill bits more than times, called deep hole
- Gun drill: only one cutting part, which was first used to process barrels. During drilling, the cutting fluid enters from the middle of the drill pipe and is injected into the cutting area through a small hole in the head of the drill bit and then removed from the V groove of the drill bit with the chip. The gun drill is suitable for deep holes with a bore diameter of 2~20 mm and a ratio of Kong Shen to aperture greater than 100. BTA deep hole drilling: the cutting fluid is fed from the gap between the drill pipe and the hole wall, and the cuttings are expelled from the inner hole of the drill pipe by the pressure of the cutting fluid. BTA deep hole drilling is suitable for drilling more than 6 mm hole diameter, hole depth and aperture ratio of less than 100 of the deep hole, and its production efficiency is more than 3 times higher than the gun drilling. The jet drilling: a multi edge deep hole drilling, inside and outside two layer drill pipe, most cutting fluid from inside and outside the drill pipe into the cutting area gap, and then together with the inner tube into the chip; the crescent hole and a small portion of the cutting fluid through the inner tube into the tail end of the inner tube jet formation, effect, low pressure area, help suction chip. The jet drilling does not require a strict cutting fluid seal. It is suitable for drilling deep holes with a diameter of more than 18 mm, Kong Shen and a bore ratio of less than 100.
- Q: What kind of drilling bit is good for stainless steel?
- The characteristics of stainless steel is high toughness, easy to stick a knife. So the drill hardness is high, surface finish better than ordinary bits, the bit angle large (130--135 degrees). At the same time to the full amount of feed and cooling. More than 0.15mm as much as possible without cutting in cold hardened layer. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.
- Q: What brand of drill iron?
- There are many kinds of drill bits, mainly based on their different uses, which is what to drill and what kind of drill bits to use.
- 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: Method for processing coolant hole of internal cooling bit
- In the western market, there are high-speed steel and powder high-speed steel internal cooling tools, their processing technology is more complex, take the core material, hot pressing, cold drawing, core pulling material, hot spin and spiral way. From product applications, there are drills, taps and reamers for internal cooling.
