Processing many metals and alloys is very difficult. The problems include cutting, which is often time-consuming and imprecise when using hand tools . To avoid this, you should reach for dedicated power tools . In the case of cutting metals, cutting machines work best.
Metal cutting machines are available in many variants, differing in parameters, as well as construction and, consequently, method of operation and purpose. But how do you choose the model that will work best in a given application? What are the differences between the different types of cutting machines? What should you pay attention to when choosing this tool? We explain this in the article.
Disc cutters
Circular saws are often referred to as saws or miter saws and are similar in design to table saws for wood. Devices of this type consist of a work table and an arm on which a disc with a motor is mounted. They are valued primarily for their efficiency and speed of work. Unfortunately, despite these advantages, they also have some disadvantages. The most important of them is the relatively low cutting accuracy. If a given job requires high precision, you should reach for a circular saw (we will write more about it in the next part).
In the case of many models, the operator is hampered by considerable noise and sparks, and the working conditions are further worsened by the metal shavings being thrown into the air. Therefore, it is necessary to provide appropriate protection when working with a cutting machine - especially protection of the ears, eyes and respiratory tract. Another solution may be to buy spark-free and dust-free models, but they are more expensive and less available.

What to look for when choosing a disc cutter? First of all, the power of the engine and the method of connection to the disc. For the device to work efficiently, the first value should be at least 2000 watts. The strength and stability of the entire structure will be ensured by ball bearings. Both requirements are met by, for example, Scheppach MT140 model available in our installation wholesale offer.
Band saws
The second type of metal cutting machines are band models. They are made of a frame on which two rotating wheels are mounted. On these, in turn, a cutting band is stretched, which, when moved, enables processing. The teeth of the band move in a closed circuit, so they pass through the same place during each rotation. This means that metal cutting machines enable very precise cutting. If accuracy is a priority in a given case, they turn out to be a very good alternative to disc models. However, it should be remembered that processing will take more time.
The efficiency and, most importantly, safety of work with a band saw depend on the correct selection of the device. The following aspects are of particular importance:
belt tension sensor prevents operation with too much slack;
strength of the frame and the entire structure;
engine power – similar to disc cutters;
the presence of a vice enabling the immobilization of the processed elements;
option to remove the base and use it as a mobile tool;
LED backlighting helps maintain full precision.
The band saws available on the market also differ in terms of how they work. We can distinguish automatic and semi-automatic models, as well as gravity (vertical). The former are the most efficient and work perfectly in professional applications.
Plasma cutters
The third type are plasma cutters – electrically conductive ionized gas. It is used to cut elements made of alloys and metals that conduct electricity, and its operation is based on the phenomenon of the current path between the electrode and the nozzle. As a result, a plasma arc is created, and then a pilot arc. The advantages of plasma cutters are primarily versatility – they allow for several cutting methods – and high accuracy. Quiet operation is also of great importance. The disadvantage, however, is the generation of a large amount of UV radiation.
The variety of cutters available on the market means that every user will choose a model tailored to their needs - regardless of their needs, the need for precision and expected efficiency.
