Grinding machine for wood. Types and features of work
The wood sander is just the perfect tool for finishing your country house. It greatly speeds up the process of perfecting any wood surface. With its help, you can put in order the old floor, wall cladding made of wood and any interior elements that have been damaged over time, including furniture.
The sander is the ideal tool for renovating and sanding wood surfaces
Currently, there are several types 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 sanders are designed for rough processing of surfaces made of wood, plastic and metal;
vibrating specimens provide smoother grinding, which is made possible by circular motions 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 places;
Old paint can be removed easily with a belt sander
The delta sander is considered a kind of vibrating fellow. It has a triangular sole and is quite convenient for grinding small grooves, corners, depressions;
another variation - 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. This device is not suitable for processing small areas and inner corners.

Draw frames: device and application
The sanding element in this equipment is represented by a tape that is attached around two rollers. Their movement allows the belt, which is attached to the sole, to rotate at the required speed. A rather important characteristic of the work of a sander on 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 select the optimal level depending on the surface to be treated.

The dimensions of the belt can also be different, depending on the model of the wood sander.The higher this indicator, the more functional the tool. However, this significantly increases the weight of the structure and its dimensions. When choosing a sander, particular attention should be paid to the grain size of the belt used. To make the work of high quality and enjoyable, it is worth purchasing various types of tapes with different grain sizes.
Important!Samples of belt sanders are equipped with a special device for collecting excess debris and dust that appears during operation. Some units are equipped with a branch pipe to which you can connect a vacuum cleaner.
In order for the operation of a belt sander to be of high quality and enjoyable, it is worth purchasing belts with varying degrees of grain size.
The quality of the tape used can be assessed by the following indicators:
the tape is elastic;
the joints do not have irregularities;
the edge of the tape is straight on both sides;
tape strength at a high level.
Flat-end belt sander allows sanding in close proximity to the wall
For large volumes of work, such equipment is equipped with a special stationary structure. Such models control the quality and depth of processing and are ideal for beginners who have no experience with such equipment. Manufacturers can offer a version of the wood sander with flat ends. This sample allows you to carry out grinding work in close proximity to the wall. An interesting function, in which the feed can be automatically filtered, will be a good help.
Vibratory sander: possibilities and applications
The principle of operation of a vibrating machine consists in vibrational movements of the surface on which the sheets of abrasive material are attached. They are held in place with special clamps or other fasteners. Such devices can be used for grinding a rather wide range of materials: metal, wood, plastic and, of course, for removing obsolete paint coatings.

The vibration amplitude can be adjusted. For "clumsy" processing settings of 4-5 mm are perfect, and for more delicate 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 outsole of this versatile tool is shaped like a reduced iron... Ideal for treating surfaces of almost any hard material. Delta sanders are used to restore old frames, shabby furniture. Due to the sharp angle on one side of the tool, it can be used in narrow and hard-to-reach places.

The operating 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 turn at different angles. There is a possibility of attaching additional attachments.
Orbital (eccentric) grinders
The main advantage of orbital sanders for wood is the finer degree of processing. The abrasive material that comes with them in the kit can have a different grain size, which also affects the quality of work. The shape of the grinding element is in this case a circle. Such models also have dust extraction through tiny holes in the outsole.

Such options are distinguished by their high speed, the number of oscillations. Setting speed and numerical indicators is an additional and very necessary function that allows you to choose the ideal operating mode for various surfaces.
Multifunctional renovator
This tool is considered to be an excellent substitute for a wood sander. It has significantly increased functionality. Besides the standard polishing and surface grinding she can:
create slots;
clean tiles or glued linoleum;
cut communication lines.
The set of the multifunctional renovator contains many attachments, the use of which greatly helps in the work
In its kit there are many attachments, the use of which greatly helps in the work. Among other grinding tools, it is distinguished by its budgetary price, very low power consumption.
Any model of grinders can be equipped with a battery. They are simply irreplaceable when carrying out long-term works in suburban areas where electricity is not yet connected.

Safety regulations
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 protective goggles.
The eccentric sander allows the surface to be processed so well that it is almost polished
Important!Do not empty the dust container without unplugging the wood sander.
When using the sander on metal surfaces, spark protection must be provided. There should be no flammable substances and other combustible mixtures in direct contact with, especially with a working device. In no case should children be allowed to approach him, in order to avoid various injuries.
