Greetings to our subscribers!
Today there will be a very useful topic that will come in handy for everyone who often cuts metal with a grinder. Over the years of working with metal, I have developed a technique for cutting with a grinder as quickly and easily as possible.
For example, I will take a small grinder on a 125 disc. Do not think that this article is about a small grinder, just as I work with a large grinder. The cutting disc is 1.6 mm thick.
We will cut a strip of metal 3 mm thick. I didn't measure the width, and it doesn't matter to us.
Let's conditionally divide the disk into sectors. By analogy with the clock, let us have 6 hours on the disk and 9 hours, for what it is, look further.
First, make a groove in the metal along the intended cutting line. We do it quickly, we don't go deep, it will be for us as a guide and a good visible landmark.
We return along the same groove to the beginning of the cut and begin to deepen into the metal. We go deep to the conditional 8 hours on the grinder's disk. Now we make a movement of the disk along the groove upwards at the intervals between 7 and 8 conventional hours. By doing these movements, we will cut the metal as quickly as possible.
With theory, everything, we saw in practice. I drew randomly 3 lines on our 3 mm strip.
All actions, as described above, make a groove along the line, return to the beginning of the line and deepen the disk until the conditional 7 or 8 o'clock. And so we will cut, deepening and raising the disc in the approximate range between 7 and 8 o'clock. The cutting speed is high, it is easy to hold the grinder, it does not bite anything.
Friends, I made a video for you, where I showed everything in detail, the ending itself is interesting, where there will be these 3 cuts in the markup.
