What is an eccentric type grinding machine?
Eccentric type grinding machines. novelty in the field of tools. They have a random trajectory of movement around the circle. In 1976, Festool from Germany presented a device in which the rotational and reciprocating movement was achieved simultaneously. After 6 years, the company produced the industrial model of grinding.
The grinding machine of an eccentric type (orbital) performs the surface processing by quality as a device polishing around the circle. But its performance is comparable to the devices with the reciprocating movement. The movement of the circle of the device occurs in random order, the trajectories are not repeated. Such a constructive solution eliminates the constant grinding of the same places and the appearance of scratches on them.
The English name of this type of device “Random Orbit Sander” is an orbital grinding machine moving along an arbitrary trajectory.
How to choose an orbital (eccentric type) grinding machine
Each eccentric type tool (orbital grinding machine) is made to certain conditions. It has a certain set of technical characteristics and is designed for a specific work cycle and load. For the right choice of a grinding machine, the factors must be taken into account:
- At what speed the rotation occurs and the amplitude of the movement. When cleaning and black grinding is carried out, a speed of 10 thousand revolutions per minute is used, the amplitude of the movement is large. This leads to an increase in performance, but to a decrease in the quality of grinding. sophisticated grinding requires a speed of 2 to 4 thousand revolutions per minute. The amplitude of the movement should be less. If you need a universal device, you can purchase and use a grinding machine of an eccentric type, in which the revolutions are adjustable, and the amplitude of the movement reaches 2-3 mm.
- What performance does the device give. This factor is affected by the size of the working surface and the selected option. Large working surface and high speed gives good performance. In a grinding machine of an eccentric type, which has an initial level, circles are used, which have a diameter of 12.5 cm. Professional devices are supplied with circles with a diameter of 15 cm.
- The duration of the working cycle and the value of the production load. So that the grinding machine has been working for a long time and operated throughout the shift and long months, the selection of parts and materials is carefully performed for its manufacture. This is the difference between an amateur tool from professional grinders. A professional tool with the same technical characteristics can cost much more.
- In what conditions will be operated by the tool. To work in places with high humidity, strong dusting, increased fire hazard, an eccentric type tool is carefully selected. For this, there are grinding machines with an increased level of protection. Operational data are indicated in the product passport. Under such conditions, you can use an eccentric type pneumatic grinding machine that does not have electricians. It can be used for any operating conditions.
Types of grinding tools
The last stage of the grinding revolution led to the appearance of mechanical devices with electric drive. Today it is difficult to find a technological operation to remove a thin layer of material, for which the tool has not been invented. These are electric beaches, electric steps and disk machines. They work on the principle of rotation and vibration, there are strip and eccentric, eat from the network and from the battery.
What is the difference between a strip from an eccentric machine? The principle of operation of the tape power tool for grinding is that the tape from abrasive material is glued into the ring and using an electric motor and pulleys is given in rotation. This makes it possible to process flat surfaces with high accuracy.
Eccentric machines have a round working platform, which, in addition to the rotational, has a reciprocal movement, achieved with a mechanism with an eccentric. This leads to a greater performance of material removal with improvement in quality.

Buyers are more popular with eccentric. These are universal models that process surfaces of any configuration. Ribbon, due to the specifics, have narrow use in those areas where there is a need for high.precision processing of large flat parts, for example, furniture.
A separate type of grinder represents vibrational. They have a flat rectangular working platform, which with the help of eccentrics is given a reciprocating movement within a few millimeters. In terms of performance are inferior to round. Used for car repair to clean up small burrs, old paint and putty.
Most of the grinder have power from the network. The tool that works from the battery is used in hard.to.reach places where the wire interferes with working 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 above. Therefore, they are not in great demand from the buyer
