Friends, today, Bulgarian-so accepted popularly called LBM, there's probably one in three men. The tool is very necessary, but one of the most dangerous to which you want to adjust, and as practice.
When cutting piece of iron, especially beginners, can often happen zakusyvanie disk, which can lead to destruction of the disc, and even injury.
The very reason for this phenomenon is the dramatic increase in frictional force to drive sawn piece of iron, rough speaking, this piece of iron acts as an instant brake caliper to the disc, if an analogy with car.
The outer edge of the disc is stopped immediately, and the inertia of the grinder mechanisms just breaks cutting disc.
How to avoid it?
When a beginner starts with a grinder, he still does not feel the instrument, so you need to be as attentive. When cutting profile tubes necessarily need something under it to put a way to cut a piece was a little on Vis, just imagine-when nearly cut off as the cut part will behave, it is necessary to make it a little sagged down, and not vice versa, otherwise zazhmom disk.
For a visual example, after cutting saw off part should be as it were a little sag, as in the photo, but it is a photo from another article, but the gist is this.
You also need to act in cutting and other material corner, circular tubes, channels. Also, when cutting these materials cut Mark up space on the shelves, both for the angle or the markup-circle for a circular pipe, also with the channel bar. Saw on the markup, do not try to do it in one cut is then, when the hand nabote.
If you have to saw some detail in the design, such as to dismantle the pipe heating or plumbing. In this case it is simply not dorezat it to the end, then enclose something in thrust-to extend the cut, and carefully In this state, finished, but it is better anyway to leave a little nedopilennym and a dolman, so it will be much safer.
If, in addition, have to cut the material with a large thickness, a channel, a thick sheet metal round timber, the valve. Then try to drive to the Bulgarian not to leave the work still in the same position, simply do not need to lower grinders in the vertical direction, or at least drive penetration in the metal will increase sharply resistance.
And it is necessary not only in the vertical position of the disc, but also to drive back and forth, starting from the edge, drive back and forth a short distance. With this method of cutting will be faster, and the probability that some snack, very small.
Another very important to familiarize yourself with the force of pressure on your grinder at work, excessive pressing force on the disc we increase the friction and mechanical and electrical overloading of their tool. So a little clicking on the disc Listen to how many will fall turnovers, allowed only a slight drop in speed, adapt to it.
Well, he knew, he said. It will be helpful if the comments are my tips complement the experienced practitioners with their observations and best practices regarding the safe operation of the grinder.
