Useful advice! The equipment should be selected taking into account the tasks for which it will be used. This is the only way the capabilities of the tool will be able to justify the cost of its purchase.
How to profitably buy a disc cutting machine for metal: an overview of tools and manufacturers
Before you start choosing the manufacturer and model of the device, it is necessary to determine the necessary characteristics. To choose the right size of the cutting disc, it is necessary to take into account two important factors: the dimensional parameters of the workpieces that will be processed on the machine, and the material from which they are made. The modification of the instrument itself depends on these nuances.
Next, you need to choose the type of placement of the structure. It can be desktop or outdoor. The second version of the equipment is used to work with massive, dimensional products. To cope with heavy loads, an electric motor with an increased power reserve is installed in such a tool, so that the operator can cut metal workpieces with a large wall thickness.
The designs of desktop modifications are mobile, so they can be used even on construction sites. With their help, you can repair various metal structures, etc.
How to choose and buy a disc cutting machine for metal
Technical characteristics are of the most important importance when choosing a metal cutting unit, since they have a direct impact on the cutting quality, equipment performance, its service life, etc.
List of technical characteristics to pay attention to when choosing a cutting tool:
- power plant power level (nominal value);
- method of torque transmission (gear or belt transmission);
- the number of revolutions per 1 min., as well as the ability to adjust their number;
- dimensional parameters of the cutting element (the size of the landing and outer diameters of the disc);
- the upper limit of the dimensional parameters of workpieces with different configuration types (permissible cross-section of a circle, pipe, plate, corner, etc.);
- the total weight of the structure, its dimensions;
- the ability to rotate the cutting block to a certain position in relation to the workpiece.
Useful advice! The most important technical parameter for a large tool with high efficiency is the CNC unit, its type. These indicators have an impact on the operation of the machine: cutting accuracy, automation and programming features. Do not lose sight of this criterion for choosing a tool.
At the final stage of selection, attention should be paid to the technical parameters of the built-in vise. The dimensions of the metal part that can be processed on the machine depend on the dimensions and indicators of this element.
Features of the choice of pendulum saws for metal
Circular saws are used for cutting profile parts of various types, the material for the manufacture of which was steel, non-ferrous metals or cast iron.
