A wood sander is simply the perfect tool for finishing in a country house. It significantly speeds up the process of bringing to the ideal of any wooden surfaces. With its help, you can put in order the old floor, wall paneling made of wood and any interior elements that have been damaged over time, including furniture.
Wood sanders: types
Currently, there are several varieties of grinding equipment, designed for use both in everyday life and professionals. The differences in the design and operation principle determine the purpose of such equipment:
- belt sanders are designed for rough processing of surfaces from wood, plastic and metal;
- Vibration specimens provide a softer grinding, which was made possible due to circular movements with a small amplitude. The surface of this grinder is made in the form of a rectangle that allows you to handle hard-to-reach places;
- Delta grinder is considered a kind of vibration counterparts. It has a triangular base and is quite convenient for grinding small grooves, corners, and recesses;
- one more version – the eccentric grinder allows to process a surface so well that it becomes almost polished. This becomes possible due to the vibrational-rotational movements that the plate makes. Such a device is not suitable for processing small areas and internal corners.
The grinding element in this equipment is represented by a tape that is attached around two rollers. Their movement allows the tape, which is fixed on the sole, to rotate at the required speed. Quite an important characteristic of the grinding machine for wood is speed. It depends entirely on the power of the tool. This figure can vary from 500 to 1200 watts. There are models that are additionally equipped with a speed regulator that allows you to choose the optimal level depending on the treated surface.
Dimensions of the tape may also be different, depending on the model of the sanding machine for wood. The more this indicator, the more functional the tool. However, this significantly increases the weight of the structure and its dimensions. When choosing a grinding machine, special attention should be paid to the grit size of the tape used. To make the work quality and enjoyable, you should purchase different types of tapes with different grain sizes.
Important! Samples of grinding machines with a belt mechanism are equipped with a special device for collecting excess debris and dust that appear in the process. Some copies are equipped with a pipe to which you can connect a vacuum cleaner.
The quality of the used tape can be assessed by the following indicators:
- the tape is elastic;
- joints do not have irregularities;
- the edge of the tape is straight on both sides;
- tape strength is high.
For large amounts of work, such equipment is equipped with a special stationary structure. Such models monitor the quality and depth of processing and are ideal for beginners who have no experience with such equipment. Manufacturers can offer the option of a wood sander with flat ends. This sample allows for grinding work in close proximity to the wall. A good feature will be a good help, in which the tape can be automatically filtered.
The principle of operation of the vibrating machine consists in the oscillatory movements of the surface on which the sheets of abrasive material are attached. They are held using special clamps or other fasteners. Such devices can be used to grind a fairly large range of materials: metal, wood, plastic and, of course, to remove old paint and varnish coatings.
The amplitude of oscillation can be adjusted. For a “clumsy” treatment, settings of 4–5 mm are perfect, and for thinner works, 1.5–3 mm. When choosing such a tool, you should pay attention to the speed of rotation and oscillatory movements, its power. The ability to regulate these indicators is an additional plus to the selected equipment.
The sole of this universal tool is made in the form of a reduced iron. Ideal for processing surfaces from virtually any solid material. Delta grinders are used to restore old frames, peeling furniture. Due to the presence of an acute angle on one side of the instrument, it can be used in narrow and hard-to-reach places.
The speed of this tool is quite high. When buying, you should pay attention to models that have the function of adjusting the speed, as well as the sole, which can be rotated at different angles. There is a possibility of mounting additional attachments.
The main advantage of orbital grinding machines for wood is considered to be a finer degree of processing. The abrasive material coming to them in the kit can have different grain sizes, which also affects the quality of work. The shape of the grinding element in this case is a circle. In such models, there is also dust removal through tiny holes in the sole.
Such options are characterized by high speed, number of oscillations. Setting the speed and numerical indicators is an additional and very necessary function that allows you to choose the ideal mode of operation for various surfaces.
This tool is considered an excellent substitute for a wood sander. It has significantly increased functionality. In addition to standard polishing and grinding surfaces, it can:
- create slots;
- clean tile or glued linoleum;
- trim communication lines.
In its set there are many nozzles, the use of which greatly helps in the work. Among the rest of grinding tools, it is distinguished by a budget price, a very small power consumption.
Important! Do not clean the dust collector without turning off the sanding machine for wood from the network.
When using the grinding tool on metal surfaces, it is necessary to provide protection against sparks. There should be no flammable substances and other combustible mixtures in direct contact with, especially the operating apparatus. In no case should children be allowed in, in order to avoid various injuries.
