Disc cutting machine for metal: scope of application

The cutting machine, designed for working with metal, is an electric tool with a high level of productivity. 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.

Disk machines are used to form blanks from materials such as:

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

Disk equipment is considered the most popular among metal cutting devices

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

Pay attention! Disk equipment is considered the most popular. Band saws and hacksaw machines are also used for cutting metal, but they are less popular.

Disk equipment is used at metalworking industry facilities, as well as at factories engaged in the manufacture of metal structures. A circular saw is used as a cutting element.

Machine designs have many advantages:

• simple structure;
• high-quality metal cutting;
• ergonomic control;
• easy operation.

The equipment can be operated by an operator who does not have special qualifications.

Automatic Disc Cutting Machine

Band-cutting machines for metal use as a cutting element a long toothed saw, which has the form of a closed tape. The material for the manufacture of this part is high-speed steel. Due to the minimum width of the cut, material losses are reduced, an accurate cut is obtained. This type of equipment is most often used in large and serial production.

A hacksaw blade is used for cutting metal workpieces in hacksaw units. It is attached to the saw frame. Such machines can have a manual or electromechanical principle of operation. Hacksaw machines are used in small enterprises and in procurement workshops.

The device of a disc cutting machine for metal

The equipment is assembled on the platform. This structure can have a metal or rigid base. 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 blanks with different configuration types are firmly held during the cutting process.

A disk made of high-speed or hard-alloy steel is used for cutting metal. Instead, a circle made of a material with an abrasive hard surface can be used.

The rotational motion to the cutting element from the electric motor is transmitted by 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.

In disk cutting devices, circles made of carbide steel or abrasive material are used as a cutting tool

Pay attention! There are modifications of machines where the disk is connected to an electric motor without a drive (directly). Such a structure has household units with low power.

Classification of cutting machines for metal cutting

Disk 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, any metal products can be processed, and in large quantities. The fourth class of equipment includes household tools.

Tool classification based on the number of cutting edges:

Single–head – there is one disk in the design, so the equipment has a low efficiency. The tool can be used exclusively to perform a single operation, for example, cutting a workpiece intended for a frame profile.

Two–head – the tool is equipped with 2 cutting elements, which allows you to perform several operations with metal at the same time. One of the heads is rigidly fixed, and the second moves. Only one operation is required to cut the frame profile, so the two-head machines can be used in automatic mode. Thanks to this, the efficiency of the tool is doubled.

Classification of equipment by the method of feeding the cutting element:

• pendulum cutting machines for metal;
• a tool with a frontal disk feed;
• a machine with a lower feed of the cutting element.

Types of machines:

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

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);

STALEX SQ-40-1 cutting machine with abrasive disc

• 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.

The device of a pendulum saw on metal

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