What is better to sand wood - a grinder or a sander?

Sanding a wooden frame not only gives the logs an external shine, but also increases their service life. Experts advise always carrying out the procedure in houses and bathhouses made of rounded logs to give the wood additional protection. To accomplish this task, use a grinder or grinder with various attachments for such work.

What is the difference between a grinder and a grinder?

The two devices that are used for sanding wooden products have significant differences. Not only in terms of the operating principle, but also in the final result. Experts say that an angle grinder will never be able to achieve perfection, unlike a well-chosen grinder.

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

Features of the grinder

An 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 sanding wheel or an attachment with sandpaper. At high speeds, the grinder rotates the disk, resulting in the processing of the log. The surface will become smooth and even, but only approximately.It will be possible to achieve the desired parameters for each beam only with the help of a grinder.

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

Characteristics of the grinder

Carpentry experts recommend using a sanding machine. There are three types of this device:

• orbital;
• tape;
• vibration.

Orbitals are used for finishing to achieve a smooth finish. They rotate around their axis with a slight displacement. Tape strips are 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 together indefinitely.

Vibratory grinders are used for intermediate grinding. The sole moves in a circle, grinding the material. Experienced carpenters use all types of devices.

What to choose for wood processing?

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

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