Q:What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?: On the other hand, putting a blade on a large cutter is not necessarily a costly mistake. The cost of the CBN blade is 8-10 times that of the carbide blade. In the use of these advanced material blades, if the cutting speed and feed is not correct, will affect product quality and tool life. Because it is difficult to realize the stock reserve, it is necessary to evaluate the processing benefit and the whole process. Value from the whole process, if we consider the adjustment and replacement of the blade time, even if the use of carbide tools with low cost to meet the requirements of tolerances and surface accuracy, so the cost is expensive. Only when the production capacity, processing cycle and blade performance are well coordinated can the actual machining capability eventually be formed.

Q:What drill is best?: The general drill is HSS high-speed steel, and if a good point is high-speed cobalt containing steel, black should be treated by blackening! Black Brown should be TIALN coated!! This drill is usually not custom-made, at most, take the standard drill bit to make a TIALN coating!!

Q:Relationship between pump pressure and bit pressure drop: Classification and nomenclature. For example, according to the drive method can be divided into electric pumps and water turbine pumps; according to the structure can be divided into single-stage pumps and multi-stage pumps; according to the use of boilers can be divided into feed water pumps and metering pumps; according to the nature of the transmission fluid can be divided into pumps, pumpsAnd mud pumps, etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps. It adopts the principle of magnetic suspension and the hydraulic structure of spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the seal structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.

Q:Want to buy a hammer, with the decoration of the house, how much more appropriate aperture: Hammer is a kind of electric drill, mainly used in the concrete slab. Brick and stone on the hole. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, it can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not suitable for open hole in the metal. But some multifunctional electric hammer, adjusted to the appropriate position with appropriate drill can replace the ordinary electric drill, electric use.

Q:What drill is used for machining holes with a diameter of 3mm?: For the steel parts which require fine matching, it is recommended to drill holes with a twist hole smaller than 3mm and then drill with a 3mm bit to ensure the accuracy of the hole. As for plastic, cardboard or copper material, the aperture will be retracted. The drill bits which are slightly larger than the diameter of 0.10mm are generally used. If the machining requirements are strict, it is better to drill rough first. For example: first drill with 2.5mm bit, and then use 3mm bit reaming, so that you can guarantee the accuracy of aperture.

Q:What do you use for drilling walls?: The hammer can drill the wall. An electric drill is out of the question. Electric drill, electric hammer, impact drill is used to punch the hammer, generally used to drill holes in the concrete and other hard objects, the drill bit is alloy steel, in drilling at the same time, the function of a hammer. An electric drill is used to drill holes in a more malleable object; the drill bit is usually steel. Both hammer percussion drill and drill function, it can be used when the hammer drill, and when. There are two kinds of drills.

Q:How many diamond grinding wheels should be used for an alloy bit?: If the hard alloy is generally 100 mesh coarse grinding, and then finishing 180, we have foreign customers dedicated to the electroplating grinding wheel are generally parallel to that, the two particle size. Plain drills and cutters use CBN wheels.

Q:Small bit drilling, drilling machine speed is fast or slow?: This size is easy to guarantee. A drill bit is to make two cutting edges for the small angle grinding symmetry, if you want to drill the round, can put some small angle grinding, namely some sharp, this bit in drilling, centering is better, the hole wall is relatively light.

Q:Impact drill and electric hammer drill is what is the difference: The drill bit is basically the same, but the bayonet is not the same, the impact of drilling is river mouth, the hammer is square!

Q:CNC machine tools I use 6.5 bit drilling out is 6.7, what method can be solved?: Also, bit clamping and grinding will also affect the drilling size to varying degrees.Remedy is:1, the size of the hole strict requirements of the workpiece, you can drill after the hinge.2, the hole size requirements are not too strict, with 6.5 or 6.6 drill directly drilling. In mass production, the first workpiece must be measured and checked.
