Also known as radial grinders, angle grinders are a widely used tool in domestic or professional jobs.
The grinder is used to sand, cut and polish different materials, especially metals and wood, thanks to an abrasive disc placed at its end that rotates at high speeds.
Uses of pneumatic grinders:
- Sanding: is the surface process to obtain a smooth and uniform finish on a surface. To achieve good sanding, abrasive sanding discs with different grain sizes are used, from the coarsest to the finest, depending on the material and the desired level of polishing.
- Cutting: To section a piece, diamond or carbide cutting discs are used, characterised by their thinness and high hardness, ideal for making straight and curved cuts on different materials such as plastics, wood, metals, tiles, etc. Angle grinders are especially suitable for cutting tasks.
- Polishing: To smooth, soften and give shine to the surface, felt or cloth discs and very fine abrasive pastes are used.
How Grinders Work:
Pneumatic models are connected to an air compressor that supplies the power needed to operate. Compressed air enters the grinder and activates an internal mechanism that rotates an abrasive wheel at high speeds. This wheel, when it comes into contact with the material to be worked, cuts, roughens or polishes it.
Types of pneumatic grinders:
There are two types of grinders depending on their shape. The angle grinder has the abrasive disc at a 90º angle to the tool axis and is suitable for cutting and grinding work. Meanwhile, the straight grinder places the abrasive disc in line with the tool axis, allowing greater control and precision for polishing and sanding work in hard-to-reach places.
Depending on their size, you can distinguish between a mini grinder and a large radial grinder. Mini grinders can reach up to 1500 W of power with discs between 115 and 125 mm in diameter. They are very light, which is why they are the most commonly used for DIY or small-scale jobs. On the other hand, large radial grinders reach 2600 W and the discs have diameters between 180 and 230 mm. The difference is the power they have, which is why they are ideal for working with very hard surfaces and materials in areas such as construction, machining parts and all kinds of professional work.
