CNC machine tools for metalworking: an overview, specifications, types and reviews

Machines with CNC for metalworking are used practically at every machine-building, pipe, repair plant. Modern cutting methods take place in an intensive mode. Control systems are based on a single service center, which is able to monitor the status of working axes and surrounding automation in real time. LCD screens provide information in a convenient graphical 3D-view.

What does the software control consist of?

For the production of precise machine parts, thread cutting of pipes, CNC machines for metal working are used. The price of installations ranges from several thousand (desktop models) to several million (multi-axis machining centers) rubles. A suitable model is selected for production purposes. The cost is reduced through the selection of pipeline versions. Single projects are estimated a significant amount, because you want to create drawings from scratch.

The machine is based on a controller that determines the following:

1. Basic reference points.
2. The coordinates of the motion along a given trajectory according to the control program.
3. The state of the analog and discrete sensors is analyzed. These include motion, level, pressure, temperature controllers.
4. The signals from the drive systems, controllers from the lines coordinated with the machine are tracked.
5. The signals are exchanged with the upper level systems.
6. With the help of built-in interfaces, fault diagnosis is simplified.
7. The control program provides error codes to the monitor. For the installer, the detection of the emergency node is facilitated.

CNC machine tools for metalworking are equipped with innovative security systems, which even expert electronic engineers can not circumvent. This increases the reliability, the safety of operation of machines and preserves the manufacturer's warranty.

Completion of installations

The accuracy of the dimensions is achieved using servo motors, stepper systems, rulers or encoders. Spare parts quickly fail because of the aggressive environment in enterprises. Cooling with coolant fluid is required when metalworking is performed on machines. With CNC in Moscow, almost all production. Western designers are introducing modern signal transmission systems with high capacity. This allows you to produce products with incredible intensity.

Pause for reconfiguration can not exceed several seconds, which makes the manufacturers of products the leaders in the industry. Time costs are reduced, and this is reflected in the cost of the final products. The line of the technological chain can be managed by one operator without the involvement of expensive specialists.

Mechanics

Modern materials reduce the influence of vibration on the frame. Wear-resistant kinematic systems provide a predetermined failure-free operation. Temperature sensors transmit information about the condition of the bearings, hydraulic system, lubrication tanks and cooling. If there is a lack of oil flow to the main loaded node - the spindle - a fault message is displayed. This allows you to maintain the integrity of an expensive item.

Before starting work, the automatic system heats the lubricating oil. Pulse dosing of the substance on the guides is carried out according to the timers. Drive systems constantly monitor the load on the kinematic nodes when driving. After exceeding the cut-off current, a stop alarm is issued through the controller. After the fault is rectified, the fault is acknowledged by the installer.

Optional equipment

Operator panels can be equipped with a hard disk. It stores all the data of archives, changes in programs, refinements in cutting technology. This option allows you to install an operating system that restores the machine's performance to a short rewrite. So, if the control card fails, the codes are transferred to the memory of the new device in minutes. Minimizes simple equipment, the enterprise does not suffer losses in the event of an accident.

CNC machine tools for metalworking are equipped with Wi-Fi transmitters, which provides a wireless transmission about the state of the lines by a hundred meters. The server collects the results of the finished product. According to the managers, such refinement helps to control the state of the production process without leaving the office.

Comparison of manufacturers

Machines with CNC for metalworking in Russia are not distinguished by the quality and reliability of Western competitors' machines. The software is more accessible due to its free download on Internet services. Western companies are still leading due to the productivity of the management centers. Designers "sharpen" the equipment for the needs of technology in an operational manner.

Leading design bureaus, founded dozens of years ago. The team of professionals is able to update the machine version on a quarterly basis. Russian analogues appear much later. But due to the low cost of installations, demand is always present.

Desktop types

Simple and inexpensive desktop CNC machines for metalworking have gained popularity. Training, the production of small parts or the need for frequent changes in the place of work of the installation are the main objectives of the acquisition of such models. Compact systems are purchased by manufacturers of printed circuit boards, electronic components.

CNC machines combine two beneficial factors:

1. Low cost.
2. Reliability and continuous operation without interruption.

Widely used in the technology of cutting sheet materials. The machines are powered by a 220 V mains supply, which makes it possible to locate the working unit in garage conditions.

Classification of machines

CNC machines for metal working are subdivided according to their dimensions, purpose, type of cutting, method of control. Each type takes into account the features of a particular production. Thus, pipe parts require several types of machines. At one enterprise are concentrated whole lines of systems, stretching for hundreds of meters.

There are several types of machines :

• Milling;
• Engraving;
• Turning;
• Grinding;
• Sheet bending and pressing equipment.

The structure is divided into the following types:

• Portal systems;
• Vertical;
• Horizontal.

Machines often buy multi-axles. According to manufacturers, even for the manufacture of simple products, at least two planes of moving the working tool are required.

Types of metalworking

Metalworking on CNC machines in St. Petersburg offers turning, engraving, thermal. All technologies are implemented in an automatic cycle. It takes minimal time to complete the order. There is no need to spend extra effort on reconfiguration. The database stores the main technological programs, it is enough to load the 3D model of the part from the portable carrier.

The final products are controlled by the department of OTC. Specialists conduct surface analysis on modern equipment. The accuracy of the manufactured parts allows companies to accept orders from the military and the space department. On CNC systems, blanks are produced in 5D-planes due to additional axes of the spindle unit movement. According to the manufacturers, with this possibility it is possible to work out all the technological holes in one cutting cycle.
