What to consider when choosing a belt sander

If the grinder selection is not too much trouble, the relative tape this can not be said.This is the question many people baffled.The different varieties of used consumables?

grain size

This characteristic is expressed in its density (pieces / inch).The higher the figure, the more "subtle" wood processing can be performed.Therefore it is recommended to start with the installation of the tape with a parameter of 65 ± 15, and ends with "fine-tuning" of the sample material with a density of 120.

type of abrasive grains are

zirconia and alumina.Begin processing the first type tape is desirable.Her "particles" sharper, so they are better suited for rough work.Including - stripping machine grinding metal against rust, in some cases - for sharpening of household tools (chisels, knives, even axes).As a result of not avoid the appearance of scratches on the surface, for its "fine-tuning" required to change the sanding belt on the canvas with an aluminum coating.Consequently, hand must always be set from the two types of materials.

What to consider when choosing

Range of depth and processing speed.The wider the range, the more types of wood species and other materials you can work this sander.

Machine eccentric

This allows the CMM to polish the wood to a state of gloss.The disadvantage is that the treatment will have to hard segments in another way, as the eccentric sanders are effective only with the correct geometry of the surface, and pre-stripped.

What to consider when choosing

method of fixing a work item.There are two possibilities - with clamps and landing on the "Velcro."What is the difference?

«Clamping» CMM, as well as consumables for it will be cheaper.Minus - to replace the work item takes more time.Is it basically up to you, the reader.
