How to choose a wood sander
When choosing a vibratory sander it is necessary to evaluate its performance, performance capabilities and additional functions. The convenience of use depends on these parameters.
The power of grinders varies on average between 150 and 1000 watts. For household applications, models with an indicator of about 350 watts are usually sufficient. If the machine is needed for professional work, it is better to choose a more powerful device.
The amplitude of the soleplate movement
Vibratory grinders have a soleplate in the process of using the unit moves from side to side with an amplitude of 1.5-5 mm. For roughing work, devices with higher indicators are well suited. For finishing sanding surfaces acquire models with a minimum amplitude.
Frequency of soleplate oscillation
When choosing a vibratory sander need to look not only at the amplitude, but also at the frequency of oscillation of the working base. The higher the index, the faster the machine will allow to perform tasks. But the quality of grinding in this case will be quite coarse, so for finishing polishing choose devices with a low frequency of vibration.
Attachment of abrasive material
Some vibrating machines support attachment of the abrasive on Velcro, others use a system of special clips. In the latter case, it takes longer to replace the work sheet. But it also holds the abrasive more reliably.
The size of the soleplate
If you process a vibratory sander to the walls, floor or ceiling, it is better to choose a unit with a long and wide platform. For use in hard-to-reach places and for polishing furniture, compact models are used.
Availability of dust collector
Grinder in the process of work produces a lot of chips and sawdust. A good tool should be equipped with a nozzle for connection of an industrial vacuum cleaner. In this case, remove debris from the treated surface can be directly in the process of sanding.
What vibration sander for wood to choose
To choose the best vibratory sander for wood, you need to determine exactly what tasks will have to solve with its help. For rough handling surfaces are well suited device power 400-600 W with an amplitude of the sole to 5 mm. If you have to sand small areas, and the quality of polishing required high, it is better to buy a unit with a base oscillation of 1 mm and a capacity of about 120-250 watts.
It should be borne in mind that low-power devices cope well only with soft wood. For sanding hardwoods, semi-professional vibrating machines are required.
Advice! If you have to process different materials with the device, it is necessary to buy a model with a speed regulator.
Choosing a sander to choose for dacha and home? Review and Types: for wood, plaster, floor, beam and log walls- Help to choose Video
Aging a piece of wood, sanded, remove paint, remove rust, mend putty, treat plastic and polish stone can be done with modern grinders. But how to choose a sander for dacha and home?
How to choose a grinder? Overview of all types: eccentric, vibratory, belt and others
Each type of grinder is designed for specific tasks: where one will show unsurpassed results, the other will be helpless. For example, eccentric grinders will not cope with the processing of internal angles, unlike their less advanced counterparts. vibrating models. In this article we will tell you about the main types of grinders. Explain the principle of their work, the scope of application and other nuances that will help determine what to buy a grinder for specific carpentry needs.
Immediately say that such options sanding tools as abrasive attachments on the drill, screwdriver or angle grinder (angle grinder), we have left out of the brackets of our conversation. They are suitable for rough sanding surfaces, but will never produce a satisfactory result in fine sanding of wooden surfaces.
Sanding wood is responsible
The sanding process may seem a formality, but it is not. The liability factor here is extremely high. Sanding imperfections that are imperceptible at first glance are immediately apparent after the finish is applied, and gross errors can easily ruin the workpiece. Scuffed layer of finish, burns on the edges, left pits and scratches, such defects are very difficult to fix; often because of them, you have to send the workpiece to scrap.
What kind of sandpaper is used?
Sandpaper is one of the oldest tools. It was first mentioned in Chinese parchment in the 13th century. The author, who is still unknown, details a recipe for making abrasive paper from shark skin and ground shells, as well as natural glue.
Interesting, That modern sandpaper was invented by John Oakey in 1883. His first invention consisted of paper to which sand and broken glass were glued. But the author did not relent and patented a number of sanding developments, including cloth polishes for shoes, furniture polishes and even chemicals for cleaning dishes.
Since then, the material has undergone many changes, but the basic principle remains the same. The production of the product took on an incredible scale, and a certain system of labeling and certification emerged. Various hard materials like silicon carbide, electrocorundum, granite, and fine-grained diamond grit are used to create a layer of abrasive.
The main characteristics
The oscillation sander is used for sanding flat, flat surfaces, ideal for working on wooden objects:
Unlike the eccentric model, the oscillating grinders have a rectangular base plate which allows you to grind corners. Larger models are more powerful and have rectangular or square soleplate.
- Pad size. the bigger the pad, the faster the surface is machined. When working with small surfaces, it is better to choose a grinder with a smaller soleplate, it will allow you to process hard-to-reach places more accurately.
- Number of oscillations. the higher it is, the better the tool works. Usually indicated as number of swings per minute.
- DeWALT DWE6411 is a powerful model with possibility of attaching Velcro paper. Paper swaps are fast, no problems. There is an option for traditional paper use. Noteworthy is the dust switch that increases tool life.
- Bosch PSS 250 AE is a high-performance sander with a powerful 250 W motor and a sanding surface of 92 × 182 mm. Working comfort is ensured by a built-in suction device, which transports the dust directly to the container with microfilter. Supplied in a suitcase with a set of sandpaper.
When choosing a belt sander for wood it is necessary to assess its technical characteristics. Several factors are important.
The power of wood sanding machines ranges from 600 to 1200 watts. The performance of the tool and its durability depends on this indicator. The more often you will use the machine, the more powerful unit is worth choosing.
On average, the weight of wood sanders is 1.5-7 kg. Heavy units are convenient for processing large horizontal surfaces. If you want to sand walls, it is better to choose a lightweight model that does not tire your hands.
Per minute, the sander can handle 200-600 meters of surface. Which machine to choose depends on the intended use and the surface area of the wood.
A good belt sander should support dust extraction, soft start and speed stabilization. All of these features increase the efficiency of the tool and protect it from premature breakage.
What belt sander to choose for home
If you want to use the wood grinder at home, it is better to give preference to models with medium power indicators. They are cheaper and more capable of performing basic tasks such as refinishing floors and furniture.
It is important to make sure that the unit is equipped with a quality dust removal system. Make sure that the wire of the machine is long enough and reaches to the socket.
Attention! When buying a device, you should take into account the need to replace consumables. It is better to choose a model from a well-known brand with standard sizes of abrasive tape.
Wood grinders: rating of the best and tips for choosing
Sanding is the last operation before finishing wood. On its quality depends on the final appearance of the finished product. In industrial conditions the process is carried out on stationary equipment, which is inaccessible to home craftsmen. However, modern hand tools allow you to get a smooth surface, in its parameters are not at all inferior to the results of processing on professional machines.
There is a large selection of sanders of different designs on sale. They are all capable of performing tasks of varying degrees of complexity and quality. Depending on the requirements of technology, models with different methods and quality of woodworking can be used. Let us consider them more closely.
How to choose the right sander for your DIY project
Which one to choose?
Ideally, in order to carry out procedures with wood, you need several sanders, one of which will perform rough finishing, and the second. finishing. It is better to carry out rough sanding with a tool with an eccentricity of 6-8 millimeters, and for finish sanding and polishing. 2-4 millimeters. If you have a limited budget, you can grind the surfaces with the help of an angle grinder. The most productive, but at the same time cheapest option is a vibratory sander.
If funds allow, it is worth giving preference to a universal orbital version. Like any other tool, the wood grinder is divided into several classes. Domestic variant is designed for short-term work with breaks. It is recommended to work with such equipment for not more than 3 hours a day, interrupted for 15 minutes.
Professional machine is able to work from 8 to 12 hours without interruption. These machines are durable, reliable and have a good working life. Such equipment is quite productive. The user has the option to choose a model with a dust collector, a vacuum cleaner, or a linear stroke.
Choose a tool that will perform all the tasks assigned to it. The main criteria for selecting a tool can include the following:
- power, which has a direct impact on the performance of the equipment;
- Length of the cord. the longer the cord, the more mobile the machine is;
- the presence of pads on the handle, which improves usability;
- The weight. if you use a heavy tool, you have to exert more effort, but these machines are easier to operate;
- smooth start;
- possibility of connecting a vacuum cleaner;
- regulation of engine speed;
- Protection against overheating.
