Metal processing has been booming for centuries, but over time, technologies, tools, and equipment differ, making things much easier.
To perform metalworking work, it must be understood that it is not easy. Only having enough skills can do the job properly, and not having the right skills, unfortunately, the results will not be gratifying. You will not need the best benchtop drill press, you will need some more equipment, tools, etc. are also important. If you want to do the metalworking yourself, you may need equipment and tools such as lathes, sheet bending machines, laser cutting machines, measuring tools, work wear and safety equipment, and more.
It is also important to mention that in order to perform different work processes with all these tools and equipment, you need to be able to work with them. When carrying out metalworking work, it is very important that everything goes as it should, and the sequence of work is as follows: heating, normalization, and hardening.
Before that, of course, all the preparatory work takes place, because you need to know what needs to be done from the metal and how to achieve it with all this equipment, so measurements, planning, etc. are needed. To find out more about this, one can only mention that the heating of the metal takes place in such a way that it is heated to the point where it turns red. This is followed by a very slow cooling process.
The metal is then cooled in the air during the normalization process. As we can see, this is not an easy job, so often those who want to do metalworking work entrust them to companies that do it.
Metal cutting is very popular at the moment. This service is being used by more and more people who need to do such work. Of course, it is possible to buy the necessary equipment and cut metal yourself, but usually, such work does not need to be done very much, so it is not worth buying everything to do this work. In this case, Kaunas metal processing is useful.

Cutting metal is a complex operation. It consists of two parts: cutting, where the chips are removed from the surface of the metal, or sawdust obtained by sawing it with a saw, and cutting when the metal without chips is divided into parts.
Metal cutting, when chips and sawdust appear, takes place in two ways: manually and by machine. By hand, the metal is cut with a saw, drilled with a hand drill, the metal surface layer is cut with a cutter, threaded with taps and thread cutters, shaved, sanded. The metal is engraved, turned, threaded, drilled and milled on machines and machines.
Cutting a metal without removing chips is its cutting and shearing.
Cutting with a hand-held hacksaw
Learning to use a hand-held hacksaw is easy, but without skills, there are some difficulties: it is difficult to start cutting, it is difficult to hold the frame straight when cutting, not to tilt it sideways, to cut exactly at the marked line, and so on.
Follow these rules when cutting with a hacksaw:
- start cutting so that the workpiece is immediately touched by three teeth, i. hold the saw at an angle to the workpiece
- when cutting a wide workpiece, tilt the saw up or down so that a smaller number of teeth touch the metal in the cut, then it is easier to cut;
- after making a few cuts, check the tape tension; tighten if necessary;
- insert the workpiece correctly in the clamps: the marked cutting point must be close to the edge of the gills, then the workpiece to be cut will not vibrate;
- tighten blanks of different profiles in the clamps;
- cut a thin sheet of metal by placing it between two wooden boards;
- start cutting in small pushes without pressing the saw, with the thumb of your left hand, from the side, holding the band;
- if you do not already have the job skills, press a wooden block instead of your thumb;
- when the cutting bar has cut a small cut and stays in it, cut while holding the saw with both hands, push forward along the entire length of the bar, first pressing harder with your left hand, through the middle of the bar with both hands evenly, and finally harder with the right;
- finish cutting in short motions by holding the saw with your right hand and holding the end of the workpiece to the left;
- when cutting a wide part, turn the cutting bar perpendicular to the frame.
- when cutting, make sure that the incision is at the marking line;
- when cutting you have to feel how the teeth cut the metal: if when sliding the saw it slips on the metal surface without resistance, then either the teeth of the band are worn or the workpiece is too hard;
- stop work, check the teeth of the saw by looking at them from above: if the tips of the teeth are shiny, they are worn;
- if you need to grind or sharpen something use a variable speed bench grinder
- check the workpiece before cutting: swipe through it with a sharp file, if the file slips, the workpiece is too hard and unsuitable for cutting.
