What happens when the angle grinder is running normally, and the switch jumps down automatically?

It should be your angle grinder.

There is a problem with the switch, the switch of the angle grinder is a spring, and he can't lock it after pushing it up, so he will jump down.

The switch of the equipment will automatically jump down under normal operation, because the equipment may be due to an automatic protection mechanism during the beating process.

It may be that the equipment leaks electricity or the power supply voltage is too low or too high, causing the machine to operate normally.

This is related to the voltage of the circuit, and the angle grinder has instantaneous high power and high current when starting. The normal voltage of the whole circuit fluctuates small, if the circuit is overvoltage, and the lower the impact on the voltage of the whole circuit, the light will flash, hope

When starting, the angle grinder has instantaneous high power and high current. The normal voltage fluctuates little in the whole circuit, and if the circuit is overvoltage, and the lower it is, the greater the impact on the voltage of the whole circuit, <>

The angle grinder is running normally, and the switch jumps down automatically, which means that there is a way of leakage, so you have to check whether there is a problem with the bolt or the angle grinder.

If this situation occurs, it should be that there is a short circuit in the circuit, so there will be such a situation, and if it hurts, you must find its entry point.

The doctor is functioning normally, which is specific to you to see some introductions on the Internet, I will check more.

Why is the machine running normally, and what is going on when it automatically falls off after the switch? This is normal.

How to run normally, what is the reason for the switch to jump down automatically? I often check it at school.

What is the reason why the grinding disc automatically falls off after the angle grinder stops rotating?

Kiss! Hello, happy to answer your <>

After the angle grinder stops rotating, the grinding disc automatically falls off for the following reasons: the most critical reason is that the diaphragm was not tightened when it was burned at the beginning, but the fixing nut was put on the grinding disc, so when the angle grinder rotated, the fixing nut wheel could not reach the degree of tightening. In the process of rotation, the speed of the diaphragm and the transmission shaft of the angle grinder is synchronized, but when the power is turned off, the transmission shaft of the angle grinder has no power support and is in a state of deceleration, but the angle grinder disc will still rotate rapidly forward due to the action of inertia, and the angle grinder disc will slip off because the direction of these two forces is opposite.

This situation is extremely unsafe, and when we use the corneal machine, we must tighten the corneal machine sheet to prevent accidents. Hope mine can help you <>

Do you have any other questions?

The angle grinder can be checked from the following aspects: 1Check whether the wiring points are plugged in and whether the terminals are loose.

2 Check to see if the stator and rotor are broken. Use a multimeter to measure whether the resistance of the two stator coils matches. 3 Check if the capacitance is normal.

4 Check if the bearing is flexible. 5 Check if the switch is normal. 6 Check the power cord and plug for damage.

Angle grinder fault classification:

1) Mechanical failure (2) Circuit failure.

Overhaul of angle grinder:

1) Common mechanical failures: Damaged or worn gears, damaged bearings. In order to be safe, after pulling out the power plug, use your hand to dial the grinding disc or shaft, if the rotor can rotate smoothly, the mechanical part is basically normal, if there is abnormal noise or jamming, it means that the gear or bearing is poorly lubricated and damaged, and it needs to be disassembled and cleaned and filled with grease or replaced with new accessories.

2) Common circuit faults: Damaged plug Broken open power cord Damaged switch Exhausted carbon brush or not in good contact with the commutator Damaged carbon brush cap or brush socket Damaged commutator Short circuit or open circuit of rotor and stator coil Poor contact at the line plug joint.

It is recommended that you focus on checking whether the carbon brush is in good contact with the rotor commutator, whether all plug-in wires and switches are good, whether the commutator is damaged, and whether the rotor and stator coils have been broken. Or follow the common faults in (1) and (2) for step-by-step detection.

There is nothing wrong with the angle grinder carbon brush, first check the power cord, then the switch, the switch is also good! You can use the plug of the multimeter angle grinder to press the switch to see if there is resistance, if not, most of the windings are burned out, you have to disassemble the angle grinder to observe the inside, to see if the commutator or something is damaged? The resistance value of the rotor winding and stator winding are measured separately.

The angle grinder is generally a brush motor, working normally means that its circuit is not a big problem, generally the brush, that is, the carbon brush after a long time of wear, it can not reach the electrode, so there is a phenomenon of stoppage or poor contact, unscrew the carbon brush protection cover, take it out to see if the carbon brush is very short, change a new one, generally a pair, and then change the angle grinder carbon brush to power off, do not be electrocuted.

Angle grinder fault classification:

Any more questions? If you're happy with my reply, please give me a thumbs up when it's over

The rechargeable type is not working when it is turned on, and it will not turn after a while.

Excuse me, do you want to ask what is the reason why the angle grinder automatically shuts down as soon as the switch is put on? The reasons for this automatic shutdown are as follows:

1. Circuit failure: loose or damaged power cord or plug, damaged power switch, thermal protector cutting off current and other problems will cause the angle grinder to stop working.

2. Overheating of the grinding head: When used for a long time or challenging difficult tasks, the grinding head may overheat, which will stop the angle grinder from working.

3. Machine failure: The failure of machine parts or internal equipment makes the angle grinder lose its working efficiency.

Hello dear, glad to answer for you, <>

The reason why the stop button of the angle grinder is still rotating when pressed: the switch is broken and cannot be broken. If it is an external power supply, then directly remove the power supply, let it stop running, and buy a switch of the same model to replace the nuclear sonor.

If you change the built-in power supply, then move the switch Sakura a few more times to see if it can stop, otherwise you can only deal with it when the battery is exhausted.

Pro, the grinding disc of the angle grinder will not automatically fall off after it is tightened, and the grinding disc will automatically fall off after the angle grinder stops rotating, indicating that the grinding disc is not tightened.

The nut of the angle grinder has a state to talk about the direction of the buried sail ant, the convex side is used to fix the thick grinding disc, and the concave side is used to lock the thin grinding disc, so the direction of the nut should be determined according to the thickness of the grinding disc.

Angle grinder, also known as grinder or disc grinder, is a kind of abrasive tool used for FRP cutting and grinding. Angle grinder is a portable power tool that uses FRP to cut and grind, mainly used for cutting, grinding and brushing metal and stone. Tongyuan electric angle grinder is to use high-speed rotating thin slice grinding wheels, rubber grinding wheels, steel wire wheels, etc. to grind, cut, rust removal, and polishing metal components.

It is suitable for cutting, grinding and brushing metal and stone, and does not use water during operation. Guide plates must be used when cutting stone. For models equipped with electronic controls, grinding and polishing can also be carried out if suitable accessories are attached to the wheels in these machines.

Summary. Hello, I am glad to answer for you: because the power of the battery-powered angle grinder is small, the torque is not enough, and if the friction between the shaft of the coil and the shaft frame is too large, the motor may be stuck, even if it is dialed, due to the friction, it is also unable to rotate, that is, the option is wrong; If it turns for a while after turning it on, then I think it's your engine that has a problem.

Or gears. It's too old to get stuck, so it can't be driven anymore.

The line and bearing are all good, but sometimes they turn and sometimes they don't, what is the problem?

After testing the wire with a multimeter, it was found that there was a break point inside, which was turned on and off, and it was fine after changing the wire.

After replacing the wire, it is still the same, that is, the sparks at the carbon brush come and go.

This is the rotor and the carbon brush contact is poor, the virtual connection caused by the ignition of the large, in the replacement of the rotor to check the lead such as check whether the upper and lower bearings of the rotor are in good condition, it is best to replace, after the installation of the carbon brush can also grind a little mu mu radian, and the rotor contact surface is larger, after installation, the rotor should be rotated by hand There should be a small Huai Nai Kai gap, and the gap will be overheated.
