Power tools have the advantages of easy to carry, simple operation and various functions, which can greatly reduce labor intensity, improve work efficiency and realize manual operation mechanization. Therefore, they are widely used in construction, housing decoration, automobile, machinery, electric power, Bridges, gardening and other fields, and a large number of families. What are the power tools?
Classification of power tools：
1, electric drill: used for metal materials, plastic and other drilling tools. When equipped with positive and negative switches and electronic speed regulating devices, can be used for electric screw batch. Some models come with rechargeable batteries.
2, electric hammer: used for masonry, concrete, artificial or natural stone drilling, and the function of the electric drill can be interchangeable. Sds-plus drill chuck and bits are widely used in light drills, and medium and heavy hammer drills are replaced with SDS-MAX chuck and bits and can be clamped with chisels.
3. Impact drill: It is mainly used for drilling electric tools of hard materials such as masonry and concrete. When the impact mechanism is closed, it can also be used as an ordinary electric drill.
4. Grinding machine: grinding tool with grinding wheel or millstone, used for grinding wood. There are direct electric grinder and electric Angle grinder. Need to install sandpaper.
5, curve saw: mainly used for cutting steel, wood, plastic and other materials, saw blade up and down reciprocating motion or swing, the most suitable for cutting accurate straight line or curve.
6, Angle mill: also known as grinding machine or disc mill, mainly used for grinding steel, metal and stone, etc. Commonly used grinding disc diameter is 100mm, 125mm, 180mm, 230mm.
7. Cutting machine: mainly used for cutting aluminum and wood from different angles. It is divided into metal cutting machine and non-metal cutting machine. 5, curve saw: mainly used for cutting steel, wood, plastic and other materials, saw blade up and down reciprocating motion or swing, the most suitable for cutting accurate straight line or curve.
8, electric wrench and electric screwdriver: Electric wrench and electric screwdriver are used for loading and unloading threaded connectors. The transmission mechanism of electric wrench is composed of planetary gear and ball spiral groove impact mechanism. The electric screwdriver uses a toothed clutch drive mechanism or a gear drive mechanism.
9. Concrete vibrator: Used for compacting concrete when pouring concrete foundation and reinforced concrete members. Among them, the high-frequency disturbance force of the electric direct-connected vibrator is formed by the rotation of the eccentric block driven by the motor, which is powered by a 150Hz or 200Hz medium frequency power supply.
10, electric planer: used for planing wood or wood structural parts, installed on the platform can also be used as a small platform planer. The cutter shaft of the electric plane is driven by the rotating shaft of the motor through the belt.
11, marble machine: Generally for stone cutting, can choose dry or wet cutting, commonly used saw blades are: dry saw blade, wet saw blade, dry and wet saw blade. Home decoration is used for cutting wall tiles.
