Sooner or later, any of us is faced with construction or renovation. Then there is a need for various works related to the removal of old paint coatings, with the preparation of wooden walls for decoration or leveling of wooden and metal surfaces.
Without mechanization, these operations turn into tedious and endless manual labor, when attempts are made with the help of sandpaper to bring the parts to be repaired to the proper form. If we add to this the continuously inhaled dust, then the question of how much the mechanization of this process costs fades into the background.
Our article provides information on who are the best manufacturers of such equipment, what is the average price and which instrument is better to buy. Each type of grinder is considered and recommendations are given on how to work with them.
The editorial staff of the site "bestx.htgetrid.com/en/" presents a rating of the best eccentric sanders and hopes that this will make it easier for you to choose the necessary equipment.

The appearance of grinding
As soon as a person had the need to sharpen the first stone knife, then the technology of grinding arose. A natural solution was found. It was necessary to use for these purposes stones with a greater hardness than the material being processed.
Along with this, people began to use the polishing of art products in order to give them an aesthetic appearance. For this, minerals differing in hardness were used - sand, pumice, shells. Even plants were used. For example, until recently, horsetails, whose stems contain silicon, were used to clean and polish metal utensils in villages. Then home-made equipment appeared in the form of grinding machines with a foot or manual drive.
Grinding Tool Types
The last phase of the grinding revolution led to the introduction of electrically driven mechanical devices. Today it is difficult to find a technological operation to remove a thin layer of material, for which no tool has been invented. These are electric files, electric beads and disk machines. They work on the principle of rotation and vibration, they are tape and eccentric, they are powered from the mains and from the battery.
What is the difference between a tape machine and an eccentric machine? The principle of operation of a belt power tool for grinding is that a belt of abrasive material is glued into a ring and is driven into rotation by an electric motor and pulleys. This makes it possible to machine flat surfaces with high precision.
Eccentric machines have a circular working platform, which, in addition to the rotary one, has a reciprocating motion, achieved using an eccentric mechanism. This results in higher material removal rates with improved quality.
Eccentric ones are more popular among buyers. These are universal models that can handle surfaces of any configuration. Due to the specificity of the tape, they have a narrow application in those areas where there is a need for high-precision processing of large flat parts, for example, furniture.
A separate type of grinders is vibratory. They have a flat, rectangular work platform, which is reciprocated by eccentrics within a few millimeters.In terms of performance, they are inferior to round ones. Used in auto repair for cleaning small burrs, old paint and putty.
Most grinders are mains powered. The tool, which operates on a battery, is used in hard-to-reach places where the wire interferes with work or when performing one-time work in the absence of electricity. Due to the fact that the battery is expensive, the price of such models with the same characteristics is higher. Therefore, they are not in great demand among the buyer.
