As one of the most commonly used and consumed power tools, angle grinders are basically the most produced models by various power tool manufacturers.
The quality is of course reflected in the technological level of the machine, raw materials, and core technology.
For the operator, the difference between "easy to use" and "useful" may be mainly reflected in
1. The degree of fit between product design and actual processing requirements (power, size, shape, etc.)
2. Durability (the machine has a strong overload capacity, the body is rigid enough, and the life of the consumable parts is long)
3. Operation accuracy and controllability (output stability of speed and torque)
4. Comfort (ergonomic design, low vibration, low noise, etc.)
Compared with other commonly used power tools, the application of angle grinders has the following characteristics:
1. Angle grinders are electric tools with high safety requirements, and safety accidents are prone to occur.
2. Due to the characteristics of the grinding operation, the angle grinder is one of the models with the highest load among commonly used power tools.
This means that it is easier to heat up, the carbon brushes wear out faster, and the failure rate of the rotor motor is higher.
3. Due to the characteristics of the working environment, the working environment of the angle grinder is very different.
For some industrial-grade grinding work, the environment may be very harsh and there is a lot of dust.
4. In some metal or stone processing industries, using an angle grinder to grind is already a fixed processing link.
Angle grinders are probably the types of power tools that will be used continuously for the longest time.
Therefore, when purchasing a good quality angle grinder, you can also consider these aspects
Sometimes, what is right for others may not be right for you.
1. National safety standards must be met. Be sure to buy brands and models that have been certified by the national CCC.
2. You must choose a model that suits your own operating requirements.
Even if it is a good-quality angle grinder, it is easy to break down if it is overloaded for a long time, and it has nothing to do with the quality.
3. Use big brand products as much as possible. The quality control of mass-produced models is often more stable.
4. For heavy-duty grinding applications, there are higher requirements for transmission parts such as bearings and casing rigidity; for working environments with a large amount of dust, attention should be paid to the air duct design of the product; cutting applications may have higher requirements for speed control.
5. If you use it for a long time, try to choose a product with better ergonomic design and rationality to reduce fatigue damage to the human body.
