Air grinder - how to choose the best one for our needs?
There are various types of grinders on the market that are adapted to different tasks. The air grinder is classified as a rotary machine and is equipped with a pneumatic drive. These devices are popular because they can be used in surface treatment, including smoothing and removing corrosion centers. For this reason, they are tools that are great for home finishing or renovation works.
Air grinder - how do air grinders work?
The air grinder is otherwise known as the air grinder. Operation of this type of devices is based on compressed air. The air grinder is powered by compressed air produced by a compressor. It is divided into two parts by a rotor. This simple mechanism creates a pressure difference. According to the rules of physics, the air must get to the other side in order to equalize it. This process sets the rotor in motion. Thanks to this part of the mechanism, the kinetic energy generated in this process is transferred to the drive system, which sets the subsequent elements of the device in motion. The rate of air transfer in this system translates into the power of the tool that uses kinetic energy. There are grinders of various power levels available on the market, so it is always worth checking the specifications of the equipment before making the final decision to buy a given model.
Among air grinders, we distinguish, among others, orbital grinders, angle grinders, finger grinders. The air orbital sander is one of the most popular because it allows for precise surface grinding. It is very useful, among other things, when carrying out renovations. On the other hand, pneumatic angle grinders are used primarily in construction works and in the metallurgical industry. Other types of air sanders include eccentric and belt sanders, among others.
A simple mechanism of operation makes the air grinder recommended due to its failure-free operation. If we want to enjoy an efficient device for a long time, we must remember, however, about a few important matters regarding the use and maintenance of tools of this type.
First of all, you should always connect the compressor and other cables correctly. It is worth checking this before each use of the grinder. In addition, pay attention to clean air - contamination or too high a level of moisture can damage the engine. To prevent this from happening, special filters are used.
Second, when using air grinders, special attention should be paid to the maintenance of the equipment. The air orbital sander and the pneumatic angle grinder can generate large amounts of dust during operation, which, if not removed, can become a threat to the efficiency of the device. Such dust absorbs moisture very well, which can contribute to the formation of a hard crust, difficult to remove and dangerous to the grinding machine's components. For this reason, it is worth cleaning the tool regularly with compressed air and a damp cloth or a soft brush. You should also take care of the correct level of lubrication of some parts.
Pneumatic orbital sander - what is it characterized by?
A pneumatic orbital sander is a great choice if we need to carry out work that requires precision from us. It is best suited for processing flat or slightly rounded surfaces. Perfect for situations where we want to achieve a uniform finish. For this reason, the air orbital sander can be used, among others, in work with varnished surfaces.
The models of pneumatic orbital sanders differ from each other, among other things, in shape, power and rotational speed. Before buying, it is worth considering what we will need the device for and choose the perfect model based on it.
For example, a pneumatic straight grinder is best suited for finishing welded surfaces and removing corrosion centers. Such equipment is a great choice for craft enterprises. The pneumatic straight grinder is characterized by high ergonomics of use, it is not difficult to operate. Users of this type of tool appreciate the convenience and freedom with which the pneumatic straight grinder can be operated. Modern models of air grinders are equipped with a comfortable handle and covers for grinding surfaces. Despite the simplicity of use, the pneumatic straight grinder is adapted to long hours of work in difficult conditions.
Other devices are also classified as grinders for similar purposes. The pneumatic eccentric sander is also best for work on flat and slightly curved surfaces. It is most often used for woodworking, but also for removing old layers of paint, especially metal. This type of device is characterized by a round disc to which discs of sandpaper are attached. The air eccentric sander makes a circular motion, but tilts slightly to the sides when rotated. We define this movement as eccentric. Such an air sander does not have a drive. It must be powered by a separate compressor. Due to its simple construction, the air eccentric sander is known for its failure-free operation.
Pneumatic angle grinder - what to use it for?
A special type of grinder is the pneumatic angle grinder, commonly known as an eraser. The pneumatic angle grinder is indispensable when working with hard materials. These include, among others, concrete, sheet metal and ceramics. Nobody who works with this type of material can imagine working without this type of air sander. The pneumatic angle grinder consists of a stator in which the rotor is placed. The next elements of the device are the attack gear and the angular gear, which connect the rest of the grinder elements together. Before starting work, the tool must be connected to a voltage source.
Such equipment is also an irreplaceable element of any construction site, metallurgical plant or shipbuilding plant. This is where you can most often find the grinders in question. Another place where a pneumatic angle grinder works perfectly are stonework workshops. In addition, due to the fact that the air-angle grinder is very well suited for processing hard materials, it is also more and more often used by people involved in the processing of specific materials or in renovations.
Undoubtedly, it is worth knowing the safety rules that must be followed when working with pneumatic angle grinders . The most important practice is to wear appropriate work clothes and to protect the eyes with work glasses. When working with a pneumatic angle grinder, there is a risk of being hit by grinding debris. Therefore, it is absolutely necessary to remember about proper eye care. Failure to exercise caution and failure to use appropriate glasses may cause the splinters to get into the eye and, consequently, permanent damage or loss of vision. It is also worth taking care of adequate respiratory protection, as large amounts of dust can be generated when using a pneumatic angle grinder. For this reason, it is worth using protective masks. In addition, earplugs are also useful, as the devices are characterized by a high level of generated noise.
Another important aspect when using a pneumatic angle grinder is that you have a suitable working space. This type of air grinder generates a significant amount of sparks during operation. It is therefore absolutely crucial that there are no flammable materials in the vicinity of the device's working area.
A disadvantage of pneumatic angle grinders is that they are not suitable for precise surface grinding. If we care about accuracy and meticulous execution of the work, it is better to choose other pneumatic grinders. In this case, the aforementioned pneumatic orbital sander will be perfect.
There is also a variety of angle grinder available on the market, ie a precision angle grinder. It is used primarily for work on steel materials, plastics and wood. It will work well in cutting, grinding and fairly precise polishing of the surface. As a rule, such equipment is used by professionals who focus on precision and quality.
The pneumatic mandrel grinder, which is often also referred to as a finger grinder, looks a bit different. If you are looking for a device that will allow you to work on small or hard-to-reach surfaces, an air spindle sander may be your best option. These types of small-size grinders are an excellent tool used in works requiring high precision.
They are used, inter alia, in the processing of glass. The pneumatic spindle sander is powered by a compressor - the device works thanks to compressed air. A pneumatic finger sander is an excellent choice when we need to deal with the finishing of small details and hard-to-reach surfaces. In these situations, an air spindle grinder is likely to perform better than a precision angle grinder.
A mini pneumatic grinder - regardless of whether we are thinking about a mandrel grinder or a smaller version of another type of grinder - it will be perfect for a home workshop where we do not usually process large surfaces, but rather small items that require precision grinding . It is this type of device that should be found in every home workshop, and its use can be really extensive.
The best air grinder is one that is suited to the tasks that we intend to perform with it. When working with this type of device, it is worth remembering about safety rules, first of all about eye protection. You should also take care of the cleanliness of the equipment on a regular basis. Thanks to this, the air grinder can serve us for many years!
