The article discusses in detail the technical and operational features of machines designed for metal cutting, and also provides a comparative description of market prices.

Disc cut-off machine for metal: scope

Cutting machinedesigned for metal working is a high performance electric tool. This type of equipment is used for cross-cutting of rolled metal blanks, as well as products made on the basis of metals and various alloys.

Disc machines are used to form workpieces from materials such as:

• corner;
• metal strip;
• rod;
• I-beam;

• shaped pipe having a round or square section;
• channel;
• other elements of rolled metal.

Note! Disk equipment is considered the most demanded. Bandsaws and hacksaws are also used for metal cutting, but they are less popular.

Disc equipment is used at metalworking facilities, as well as in factories that manufacture metal structures. A circular saw is used as a cutting element.

Machine-tool designs have many advantages:

• simple structure;
• high-quality metal cutting;
• ergonomic control;
• ease of use.

The equipment can be operated by an operator without special qualifications.

Band-cutting machines for metal use a long toothed saw as a cutting element, which looks like a closed belt. The material for the manufacture of this part is high-speed steel. Thanks to the minimum kerf, material wastage is reduced and an accurate cut is obtained. This type of equipment is most often used in large and mass production.

A hacksaw blade is used to cut metal blanks in hacksaw units. It is attached to the saw frame. Such machines can be manual or electromechanical. Hacksaw machines are used in small enterprises and in procurement shops.

The device of a disk cutting machine for metal

The equipment is assembled on the platform. This design can be metal or rigid. Moreover, the placement of the components of the machine is not stationary, but removable. A vise with a reliable stop is installed on the tool, thanks to which workpieces with different types of configuration are firmly held during the cutting process.

For cutting metal, a disc made of high speed or carbide steel is used. Instead, a wheel made of a material with an abrasive hard surface can be used.

The rotary movement is transmitted to the cutting element from the electric motor due to a gear or belt drive. The first option is installed on stationary equipment with a high power reserve, the second is suitable for compact tools with a portable design.

Note! There are machine modifications where the disc is connected to an electric motor without a drive (directly). Such a structure has household appliances with low power.

Classification of cutting machines for cutting metal

Disc equipment for metal cutting is divided into 4 classes. A tool belonging to the first category is considered universal. With the help of such machines, you can process any metal products, and in large quantities. The fourth class of equipment includes tools for household use.

Tool classification based on the number of cutting edges:

1. Single-head - there is one disc in the design, so the equipment has a low efficiency. The tool can only be used for performing one operation, for example, cutting a blank for a frame profile.
2. Two-head - the tool is equipped with 2 cutting elements, which allows performing several operations with metal simultaneously. One of the heads is rigidly fixed, and the other moves. It only takes one operation to cut the frame profile, so the double-head machines can be used in automatic mode. Thanks to this, the efficiency of the tool is doubled.

Equipment classification by the method of feeding the cutting element:

• pendulum cutting machines for metal;
• tool with front disc feed;
• machine with bottom feed of the cutting element.

Varieties of machines:

• correct and detachable;
• abrasive cut-off;
• cutting saws.

Useful advice! Equipment should be selected taking into account the tasks for which it will be used. Only in this way can the tool's capabilities justify the costs of purchasing it.

How to buy a disc cutting machine for metal profitably: an overview of tools and manufacturers

Before proceeding with the choice of the manufacturer and model of the device, it is worth deciding on the required characteristics. To correctly select the 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 select the type of structure placement. 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, such a tool is equipped with an electric motor with an increased margin of power, so that the operator can cut metal workpieces with a large wall thickness.

Constructions 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 disk cutting machine for metal

When choosing a machine for cutting metal, technical characteristics are of paramount importance, since they have a direct impact on the quality of cutting, equipment productivity, its service life, etc.

List of technical characteristics that you should pay attention to when choosing a cut-off tool:

• power level of the power plant (nominal value);
• method of transmission of torque (gear or belt transmission);

• the number of revolutions per 1 minute, as well as the ability to customize their number;
• dimensional parameters of the cutting element (size of the landing and outer diameters of the disc);
• the upper limit of the dimensional parameters of blanks with a different type of configuration (the permissible size of the section of a circle, pipe, plate, angle, etc.);
• total weight of the structure, its dimensions;
• the ability to rotate the cutting unit 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: cut accuracy, automation and programming features. Do not lose sight of this criterion for choosing a tool.

At the final stage of the selection, you should pay attention to the technical parameters of the built-in vice. The dimensions and indicators of this element determine the dimensions of a metal part that can be machined on a machine.

Features of the choice of pendulum saws for metal

Circular saws are used to cut various types of profile parts, the material for which is steel, non-ferrous metals or cast iron.

The machines cope with cutting of the following types of rolled products:

• square;
• channel-type;
• round;
• I-beam;
• rectangular.

The equipment is suitable for small-scale or one-off production of parts.

Scope of application:

• furniture manufacture;
• Finishing work;
• carpentry work;
• installation work.

Based on what type of workpiece is used, a specific type of disc is selected and its speed is adjusted. The cut can be made at any angle.

Due to the fact that the rotation of the disc circumference is carried out at high speed, and also the power capabilities of the drive of the machine itself are added to this indicator, the cutting element wears out very slowly. At the same time, the efficiency of cutting metal is maintained.
