Types of Grinding Machines
When performing one task, a different result comes out thanks to the power tool. So, they distinguish:
- Machines for rough finishing.
- For medium grinding.
- For the finish preparation.
Also, manufacturers offer to purchase devices for polishing the surface. Then it becomes smooth with a touch of gloss.
Angle Grinder (UShM)
For wood processing, a petal disk or circles in the form of a plate with sandpaper are used. The latter changes easier and faster if you use a Velcro nozzle.
Thanks to the rotational movement, the process of stripping and leveling takes less time than if a tool with a different nature of work is used.
Wood dust with sandpaper is easily cleaned with a brush or brush with a medium hard pile. Another option also involves the removal of wax. It is enough to grind the metal plane within a minute (possible less).
Belt Sander (LSHM)
As a nozzle, a closed sandpaper (endless) is used. It is set in motion by a mechanism equipped with rollers. The tape is mounted on them.
The advantage of tape machines is the area of the working surface. Compared to angle grinder, it is larger. Accordingly, wood processing takes less time.
Grinding of corners, grooves and gaps between parts is difficult. Due to the weight of the device, vertical structures and tops are more difficult to handle. In addition, LSM emit a lot of noise, and grinding occurs only in the central part of the sole.
Orbital or eccentric grinding machine (OShM, EShM)
Most models are equipped with garbage containers with filter plates or have access to a connection to a separate construction vacuum cleaner.
The orbital machine is equipped with a mechanism only for ensuring circular motion. The eccentric additionally produces a reciprocating. Due to the latter, ESM is considered more effective.
Machines are used for any grinding. They work without noise, weigh a little, and hard-to-reach places can be processed (unlike LSHM). The radius of rotation is 3-8 mm. Disadvantages: the inability to process corners and the fact that the edges are ground with less efficiency than the central part.
Vibratory Grinding Machine (VSHM)
The sole can be in the form with three and 4 corners. The work platform copes with surface treatment in almost all hard-to-reach places.
Solid elements under sandpaper are pressed into the tree, which leads to the formation of grooves and scratches. This can be eliminated if you first clean the surface, plug in a vacuum cleaner, periodically sweep away trash and change the blade with a finer abrasive.
Oscillation Grinding Machine (MFI)
A multifunctional tool is otherwise called a renovator, multi-tool and multi-cutter. It is intended, among other things, for grinding all hard-to-reach spots. To do this, set a flat triangular platform.
Designed by MFI for restoration and processing of small-area material. This is due to the small amplitude of the oscillations. The grinding result is accurate and high quality.
What are the rules for choosing a grinding machine
Initially, goals are defined. For example, for a rough finish, it is better to choose devices with a rotational movement of the sole, and an eccentric or vibration machine is better for intermediate and finish grinding. And in the manufacture of furniture you can’t do without MFIs.
The main criteria:
- power varies from 0.6 to 3 kW (0.8 units are enough for a house, at least 1.5 for permanent operation);
- the sole area depends on the scale and accuracy of the work;
- the presence of a speed controller;
- connecting a vacuum cleaner or filter will provide less dust;
- powered by mains or battery;
- weight, protection against damage, comfort during use and ease of maintenance.
Important! It will be more practical to choose a tool with which you can perform more than one task. For example, a grinder for global events or a renovator for small works are multifunctional.
The best manufacturers in the household series
As a rule, an instrument of this category is used within 3 hours per day. At the same time, periodic breaks of 15 minutes are not taken into account. Cars for rare use are purchased.
So, in the region of 1500-5000 rubles there are grinding machines from well-known manufacturers:
- Bosch (Germany). The household tool is green (not blue). Compared with other manufacturers, the cost is slightly higher, but the quality is noticeably superior.
- Interskol (Russia). Quality and accessibility at a high level. The tool is assembled using imported parts.
- Hammer (Germany). Assembling from original components is carried out at factories in different countries.
- Patriot (USA). Production is established in Russia, Korea, Italy and in China.
- Zubr (Russia). The brand is known for its low prices for tools for the home.
The price is affordable, and the equipment, weight and technical characteristics are minimal.
The best manufacturers in the professional group
This group of products includes instruments with high technical characteristics. They have a large working resource and are designed for active use as directed. The package almost always includes a suitcase for storage and additional equipment.
The list of manufacturers is as follows:
- Festool (Germany). The manufacturer specializes in the manufacture of wood processing equipment.
- Makita (Japan). Great quality at an affordable price.
- Bosch (Germany). The assortment is represented by equipment that most buyers can purchase.
- DeWalt (USA). It differs from the first only in high cost, but not in characteristics.
- Metabo (Germany). The disadvantage is only a large price tag.
- Hitachi (Japan). In no way inferior to the leaders.
All professional tools are made on the basis of original equipment and with native components.
