Q: Can twist drills drill through wall tiles?: If the bathroom has posted a good ceramic tile, and brick or cement is uncertain under the wall, first with triangular or cross drill drill drill tile in ordinary pistol, and then use the hammer drill or drill drill cement wall. Although you can achieve the function of impact drill hammer drill, but no more labor-saving electric hammer drill.

Q: What drill holes are used to break the screw?: If the screw is broken and the drilling is not good, it is recommended to solve the problem with edm. A six or a slot is machined at the broken screw and then the screw is broken inside with a six square wrench or screwdriver. The electrode size is different, can process different sizes of broken screws, M3-M50 can.

Q: What's the difference between full mill and rolling twist drill?: The mill is the whole cutting molding drill, rolling is half full grinding material pressure after a long drill, the above material is less than half, so the hardness will be affected, anyway, the rolling twist drill is not good! Without the use of, respectively, rolling and full grinding, just look at the groove can be, there are obvious texture grinding marks are all grinding, and, conversely, messy, irregular rolling.

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: What drills do we use to drill jade?: Use of modern ultrasonic drilling machine, the principle of high frequency vibration generated by the ultrasonic wave, the small needle drill under high speed moving, driven by abrasive drilling. Due to the small drill needle does not rotate, just move up and down reciprocating frequency. Therefore, the quality of drilling is very high and the holes are evenly distributed up and down.

Q: What is the maximum available drill bit for an electric drill with a maximum diameter of 10mm?: Of course, if it is not a cylindrical drill, but a hole opener, it can be as large as 100mm and open a round hole on a low density material such as a large board.

Q: How can we change an ordinary drill bit into stainless steel?: With ordinary stainless steel drill bits to drill, speed down, such as 100, add a little vinegar when drilling well drilling. In two, the lowest drill about three hundred rpm, speed a little faster. It is better to drill on the vertical or rocker arm, and the speed can be adjusted lower.

Q: 14 what big expansion wire does the drill use?: Different expansion bolts form different drill diameters, and the maximum outer diameter of the bolt can be measured.

Q: 1.5 of the stainless steel plate to drill 1.2 holes, the drill has broken a lot of roots, what kind of material with a bit better? How much speed, how much feed?: When drilling a stainless steel material, it is better to add some vinegar to the drill so that it will be easy to drill. Stainless steel drilling, the speed can not be high, high, easy to drill bit. 1.2mm hole, the speed hit 1000 rpm almost. In addition, the drilling of stainless steel, it is very hard to drill, the drill is not fast, and timely grinding, do not force to drill down, it will easily break the drill.

Q: Sharpening of drill angle when machining different materials: For drilling soft materials, the drill points can be sharpened. As to why such a grinding bit is made, it is because the harder material can hold the bit, so that the bit does not swing too much, and the diameter of the drilled hole can meet the requirements. Soft material drilling, if the drill is relatively flat, because the material is relatively soft, can not cover the drill bit, so that drilling out of the size of the hole is too poor.
