What Is an Air Sander?
An air sander is a pneumatic tool used for grinding and polishing materials, such as metals and resins, using the power of compressed air. By changing the abrasive pads and grinding wheels, you can choose how to use the sander. Some grinding wheels can also be used for cutting.
A similar type of sander is an electric sander that runs on electricity. An air sander is slightly less powerful, but many are smaller and lighter than electric sanders, making them suitable for light work.
Compressed air is used, necessitating the use of a compressor.
How to Use Air Sanders
To use an air sander, connect it to a compressor, which is the power source, and turn on the startup switch. When replacing the pad, disconnect the connecting hose to avoid malfunction.
Some types of air sanders are suction type and are designed not to scatter dust around. However, non-suction types will scatter dust during sanding. Protective equipment such as goggles and masks should be worn to prevent dust from getting into the eyes or being inhaled during operation.
How to Choose Air Sanders
There are various types of air sanders based on their movement, pads, and wheels. It is essential to choose the type that best fits your specific purpose of use.
- Air Angle Grinder
Air angle grinders are tools that perform grinding and cutting by attaching a grinding wheel to a rotating shaft and rotating it. Grinding and cutting can be switched by changing the type of grinding wheel. By changing the grinding wheel to a buffing wheel, grinding can also be performed. When changing the grinding wheel, it is necessary to check by turning it lightly because if the wheel is eccentric, it will vibrate very strongly, which is dangerous. - Pencil Sander
Pencil sanders are shaped like a pen. It has a thin file and can be used for fine sanding. With a fine-tipped sander, grooves can also be dug. - Air Double-Action Sander
The air double-action sander is an air sander with a rotating pad. It has strong sanding power and can be used for roughing to finishing. The rotating shaft is eccentric, and the larger the eccentricity, the higher the sanding power.
