A wood sander is just the perfect tool for decorating a country house. It significantly speeds up the process of bringing to the ideal of any wooden surfaces. With its help, you can tidy up the old floor, wall cladding of wood and any interior elements that are damaged over time, including furniture.
Types wood sanders
Currently, there are several varieties of grinding equipment designed for use both in everyday life and by professionals. Differences in design and in principle of operation determine the purpose of such equipment:
- belt grinders are designed for rough processing of surfaces made of wood, plastic and metal;
- vibrational specimens provide a softer grinding, which is made possible by circular movements with a small amplitude. The surface of such a grinder is made in the form of a rectangle, which allows you to process hard-to-reach spots;
- the delta grinder is considered a type of vibrating counterparts. It has a triangular sole and is quite convenient for grinding small grooves, corners, indentations;
- another variety – the eccentric sander allows you to process the surface so well that it becomes almost polished. This becomes possible due to the vibrational-rotational movements that the plate makes. Such a machine is not suitable for processing small areas and internal corners.
Wood sander machines: device and application
The grinding element in this equipment is represented by a tape that is mounted around two rollers. Their movement allows the tape, which is mounted on the sole, to rotate at the required speed. A rather important characteristic of a wood sander is speed. It completely depends on the power of the tool. This indicator can vary from 500 to 1200 watts. There are models that are additionally equipped with a speed controller, which allows you to choose the optimal level depending on the surface being machined.
The dimensions of the tape can also be different, depending on the model of the grinder on wood. The higher this indicator, the more functional the tool. However, this significantly increases the weight of the structure and its dimensions. When choosing a grinder, special attention should be paid to the grain size of the tape used. In order for the work to be of high quality and give pleasure, it is worthwhile to purchase various types of ribbons with different grain sizes.
Important! Samples of belt grinding machines are equipped with a special device for collecting excess debris and dust that appear during operation. Some copies are equipped with a pipe to which you can connect a vacuum cleaner.
The quality of the tape used can be estimated 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 at a high level.
For large volumes of work, such equipment is equipped with a special stationary design. Such models exercise control over the quality and depth of processing and are ideal for beginners who do not have experience with such equipment. Manufacturers can offer a version of a wood grinding machine with flat ends. Such a sample allows grinding work in close proximity to the wall. An interesting feature will be a good help, in which the tape can be automatically filtered.
Vibratory sander: features and applications
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 by special clamps or other fasteners. Such devices can be used for grinding a fairly wide range of materials: metal, wood, plastic, and, of course, for removing obsolete coatings.
The amplitude of the oscillations can be adjusted. For “clumsy” processing, settings of 4-5 mm are perfect, and for finer work – 1.5-3 mm. When choosing such a tool, you should pay attention to the speed of revolutions and oscillatory movements, its power. The ability to regulate these indicators is an additional plus for the selected equipment.
Delta Sander: Features and Benefits
The sole of this universal tool is made in the form of a reduced iron . Ideal for surface treatment from virtually any hard material. Delta sanders are used to restore old frames and shabby furniture. Due to the presence of an acute angle on one side of the tool, it can be used in narrow and inaccessible places.
The speed of such a tool is quite high. When buying, you should pay attention to models that have a speed adjustment function, as well as a sole that can be rotated at different angles. It is possible to attach additional nozzles.
Orbital (eccentric) grinders
The main advantage of orbital sanding machines for wood is considered a finer degree of processing. The abrasive material that comes to them in the kit may have different grain sizes, which also affects the quality of work. The shape of the grinding element in this case is a circle. In these models, there is also dust extraction through tiny holes in the sole.
Such options are distinguished by high speed, number of oscillations. Setting speed and numerical indicators is an additional and very necessary function, which allows you to choose the ideal mode of operation for various surfaces.
This tool is considered an excellent substitute for a wood sanding machine. It has significantly increased functionality. In addition to standard polishing and grinding of surfaces, it can:
- create slots;
- clean tile or glued linoleum;
- cut communication lines.
In its kit are many nozzles, the use of which greatly helps in the work. Among the other grinding tools it is distinguished by the budget price, very small power consumption.
Wood sanders require special attention to safety. To protect yourself from unpleasant problems you need to observe the following subtleties:
- put on headphones;
- purchase a respirator;
- Do not neglect safety glasses.
Important! Do not clean the dust bag without turning off the sander on the wood from the network.
When using a grinding tool on metal surfaces, spark protection must be provided. In direct contact with, especially the working apparatus, flammable substances and other combustible mixtures should not be. In no case should you allow children to avoid various injuries.
