Q:What's the role of carbon brushes in electric tools?

Changing the direction of the current (in the commutator motor brush, also plays a role reversal)

Q:What material does the power tool housing fit?

Electric drill: the main specifications are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm and so on. The figures refer to the steel whose tensile strength is 390N/mmThe maximum diameter of a drill drilled on a material. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. An electric screwdriver adopts a clutch, a transmission mechanism, or a gear drive mechanismThere are M1, M2, M3, M4, M6 and so on.

Q:What's the name of an electric tool for riveting screws into wood? Not understand!

An electric drill can be used! But it can't adjust the torque! There are four types of professional screw twisting tools!

Q:What kind of power tools are hand drills? 1, 2 or 3?

You can see the cable plug, the aluminum shell is inserted three I tools, is grounded, the aluminum shell and some II tools, because it has a plastic insulation between the stator and the aluminum shell, so it is the installation of two wire plug.

Q:What devices must be available for all hand held electric tools?

Hand held electric tools, insulation measures are in good condition, must be equipped with qualified leakage protection device, forbid to change the power cord and plug, use special flow switch box.

Q:Compared to pneumatic tools, what are the advantages of electric tools?

At the same time, reversing operation, pneumatic tools, small size, high speed rotary speed, easy to adjust, no danger of fire, the air compressor can also be used in the house, is the best choice for sheet metal, paint, furniture manufacturing, auto hub processing, etc..

Q:What are the common rotors of power tools?

Hammer and drill: used for concrete, brick and building components on drilling, slotting, dehairing. With expansion bolts, installation can improve the speed and quality of pipeline, machine equipment; impact hammer principle is to rely on the internal movement of the piston impact force, impact principle of impact drill is running in gear impact force, so the impact hammer is greater.Concrete vibrator: used for pouring concrete foundation and reinforced concrete members, tamping concrete to eliminate air holes and increase strength. The high-frequency disturbing power of the electric direct acting vibrator is driven by an electric motor to rotate the eccentric block, and the motor is powered by an 150Hz or 200Hz intermediate frequency power supply.The planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive.Electric tools commonly used bearing type: 606, 607, 608, 626, 627, 628, 629, 6000, 6001, 6003, 6004, 6200, 6201, 6202, 6203, 6303, 61907, 688 commonly used carbon brush models: 50#, 408#, 43#, 44#, 303#, 21#, 6M etc.

Q:What's the difference between a flashlight and an electric screwdriver?

As the mechanical component, the electric screw driver can work without the electric batch power supply, and the batch power supply provides the energy and the related control function for the electric screwdriver. Drive the motor. Since the parameters of the motor are different, the speed will be different when the power of the batch power supply is the same.

Q:What are the commonly used rotor types for power tools?

Electric drill: the main specifications are 4, 6, 8, 10, 16, 19, 23, 25, 32, 38, 13, 49mm and so on.

The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. The electric screwdriver adopts the embedded clutch, transmission mechanism or gear drive mechanism. The specifications include M1, M2, M3, M4, M6 and so on.The hammer and drill: used for concrete, brick and building components on drilling, slotting, dehairing. With expansion bolts, installation can improve the speed and quality of pipeline, machine equipment; impact hammer principle is to rely on the internal movement of the piston impact force, impact principle of impact drill is running in gear impact force, so the impact hammer is greater.

Q:Is Li Xiang power tool good?

I was doing a power tool, you said this is a good point, I suggest you buy brand electric tools, East into a really good, but you buy when I suggest you go to the East into the store to buy if to go to other places to buy will be expensive, and not necessarily the East into true. There are a lot of imitation in East into sell, buy electric tools as long as buy a good brand of machine authentication
