The better to grind wood: grinder or grinder, tips

Grinding a log house not only gives the logs an outer shine, but also increases the service life. Experts advise to always carry out the procedure in houses and saunas made of rounded logs to give the wood additional protection. To accomplish the task, use a grinder or grinder with various attachments for such work.

What is the difference between a grinder and a grinder

The two instruments that are used for sanding wood products have significant differences. Not only on the principle of work, but also on the final result. Experts say that a grinder will never be able to achieve perfection, in contrast to a well-chosen grinder.

Before starting work, it is important to define for yourself the expectations of the process. The choice of device will depend on this.

Features of the grinder

The angle grinder or angle grinder is a multifunctional device that is used to implement various projects. Depending on the selected attachment, you can process surfaces, saw, cut, peel and more.

When processing wood, use a flap wheel or a nozzle with sandpaper. At high speeds, the grinder rotates the disc, as a result of which the log is processed. The surface will become smooth and even, but only approximately. It will be possible to achieve the desired parameters for each bar only with the help of a grinder.

Note that the grinder works much faster. The disadvantage is the need to keep the machine on weight. In addition, the process generates a huge amount of dust and cuts that fly towards the operator. You will need protective clothing, a respirator and goggles.

Grinder characteristics

Carpentry experts advise using a sander. There are three types of this device:

• orbital;
• tape;
• vibrating.

Orbital are used for finishing to achieve smoothness. They rotate around their axis with a slight offset. Tape is used at the first stage to carry out rough processing and remove a thick layer of wood. They look like two rollers that drive a special tape glued to infinity.

Vibrating ones are used for intermediate grinding. The outsole moves in a circle, sanding the material. Experienced carpenters use all types of appliance.

What to choose for wood processing?

The answer to the question asked depends on the final result that the person plans to receive. If we are talking about absolute evenness and smoothness for subsequent staining, we turn to a sander. For rough processing and visual effect, a grinder is enough.

Note that competent grinding involves a gradual increase in the grain size of the nozzles. To begin with, take paper with an indicator of 60, then 80, and finish 150-180. This parameter is sufficient for processing wooden surfaces and logs. After completing the process with the tool, sandpaper it by hand. So the appearance after painting will not be spoiled by scars from the device.
