Disc cutting machine for metal: scope
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 metal billets, as well as products made on the basis of metals and various alloys.
Disk machines are used to form blanks from such materials as:
- metal strip;
- double tee;
- the profile pipe having round or square section;
- other elements of metal.
Note! Disk equipment is considered the most popular. Bandsaws and hacksaws are also used for cutting metal, but they are less popular.
Disk equipment is used at the facilities of the metalworking industry, as well as at factories engaged in the manufacture of metal structures. The saw blade is used as a cutting element.
Machine structures have many advantages:
- simple structure;
- high-quality metal cutting;
- ergonomic control;
- ease of operation.
The operator can work with equipment that does not have special qualifications.
Metal band cutting machines 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 loss is reduced, an accurate cut is obtained. This type of equipment is most often used in large and mass production.
For cutting metal blanks in the hacksaw units, a hacksaw blade is used. It is mounted on the saw frame. Such machines can have a manual or electromechanical principle of operation. Hacksaws are used at small enterprises and in procurement workshops.
Equipment assembly is carried out on the platform. This design may have a metallic or rigid base. Moreover, the placement of the components of the machine is not stationary, but removable. The tool is equipped with a vise with a reliable stop, thanks to which, in the cutting process, workpieces with a different type of configuration are firmly held.
For cutting metal disc is used, made of high-speed or carbide steel. Instead, it can be used a circle made of a material with an abrasive hard surface.
The rotational movement of the cutting element from the electric motor is transmitted through 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 modifications of machines, where the disk connects to an electric motor without drive (directly). Such a structure have household units that have a small capacity.
Disk equipment for cutting metal is divided into 4 classes. A tool belonging to the first category is considered universal. With the help of such machines can handle any metal products, and in large quantities. The fourth class of equipment includes household appliances.
Classification tool based on the number of cutting edges:
- Single head – the design has one disc, so the equipment has low efficiency. The tool can be used exclusively to perform a single operation, for example, cutting a workpiece intended for a frame profile.
- Double head – the tool is equipped with 2 cutting elements, which allows you to simultaneously perform several operations with metal. One of the heads is rigidly fixed, and the second moves. To cut the frame profile requires only one operation, so double-head machines can be used in automatic mode. Due to this, the efficiency of the tool is doubled.
Classification of equipment according to the method of filing the cutting element:
- pendulum cutting machines for metal;
- tool with frontal disk feed;
- machine with the lower feed of the cutting element.
Varieties of machines:
- correct and detachable;
- abrasive cutting;
- saws detachable.
Helpful advice! Equipment should be selected taking into account the tasks for which it will be used. Only in this way the ability of the tool will justify the cost of its purchase.
Before proceeding to the choice of the manufacturer and model of the device, it is necessary to determine the necessary characteristics. In order to choose the size of the cutting disk correctly, it is necessary to take into account two important factors: the dimensional parameters of the blanks that will be processed on the machine and the material from which they are made. The modification of the tool itself depends on these nuances.
Next you need to select 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, thanks to which the operator can cut metal workpieces with a large wall thickness.
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.
When selecting a machine for cutting metal, technical characteristics are of paramount importance, since they have a direct impact on the quality of cutting, equipment performance, its service life, etc.
The list of technical characteristics that you should pay attention to when choosing a cutting tool:
- power level of the power plant (nominal);
- method of transmitting torque (gear or belt drive);
- the number of revolutions per 1 min., as well as the ability to customize their number;
- dimensional parameters of the cutting element (the size of the landing and outer diameters of the disk);
- the upper limit of the dimensional parameters of workpieces with different types of configuration (the permissible value of the cross section of a circle, pipe, plate, corner, etc.);
- the total weight of the structure, its dimensions;
- the ability to rotate the cutting unit to a certain position in relation to the workpiece.
Helpful 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 work of the machine: cutting accuracy, automation and features of programming. Do not lose sight of this selection criterion tool.
At the final stage of the selection should pay attention to the technical parameters of the built-in vice. The dimensions and indicators of this element depend on the dimensions of the metal part, which can be machined.
Circular saws are used for cutting profiles of various types, the material for the manufacture of which served as steel, non-ferrous metals or cast iron.
Machines cope with cutting rolled products of the following types:
The equipment is suitable for small-scale or single parts manufacturing.
Scope of application:
- furniture manufacture;
- Finishing work;
- assembly work.
Based on what type of workpiece is used, a disc of a certain type is selected and the frequency of its revolutions is adjusted. The cut can be performed at any angle.
Due to the fact that the rotation of the disk circle is carried out at high speed, as well as 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 metal cutting is maintained.
