CNC machines for metalworking are used in almost every machine-building, pipe, and repair plant. Modern cutting methods are intensive. The control systems are based on one service center, which is able to monitor the status of the working axes and the surrounding automation in real time. LCD screens provide information in a convenient graphical 3D view.
What does program management consist of?
For the production of precision machine parts, pipe threading, CNC machines are used for metalworking. The price of installations ranges from several thousand (desktop models) to several million (multi-axis processing centers) rubles. A suitable model is selected for the production tasks. Cost is reduced by choosing conveyor versions. Single projects are estimated by a significant amount, because it is required to create drawings from scratch.
The machine is based on a controller that determines the following positions:
- Base reference points.
- Coordinates of movement along a given trajectory according to the control program.
- The state of analog and discrete sensors is analyzed. These include motion controllers, level, pressure, temperature.
- Signals from drive systems, controllers from lines coordinated with the machine are monitored.
- Signals are exchanged with upper-level systems.
- Integrated interfaces simplify troubleshooting.
- The control program issues error codes to the monitor. For the installer, the detection of an emergency site is facilitated.
CNC machines for metalworking are equipped with innovative safety systems that even experienced electronic engineers cannot get around. This increases the reliability, safe operation of the machines and maintains the manufacturer's warranty.
Complete set of installations
Dimensional accuracy is achieved using servomotors, stepper systems, rulers or encoders. Spare parts quickly fail due to the aggressive environment in enterprises. Coolant fluid cooling is required when metalworking is done on machines. Almost all manufactures work with CNC in Moscow. Western designers are introducing modern signal transmission systems with high bandwidth. This allows you to produce products with incredible intensity.
The pause for readjustments may not exceed several seconds, which makes product manufacturers leaders in the industry. Reduced time costs, and this affects the cost of final products. A line of a technological chain can be controlled by one operator without involving expensive specialists.
Mechanics
Modern materials can reduce the effect of vibration on the bed. Wear-resistant kinematic systems provide the specified failure-free operation mode. Temperature sensors transmit information about the state of thrust bearings, hydraulic systems, lubrication and cooling tanks. If there is a lack of oil flow to the main loaded unit - the spindle - a fault message is issued. This allows you to maintain the integrity of the expensive element.
Before starting work, the automatic system heats the lubricating oil. Pulse dosing of the substance on the guides is carried out by timers. Drive systems constantly monitor the load on the kinematic nodes when driving. After exceeding the cutoff current, a stop alarm is issued through the controller. After troubleshooting, the error is acknowledged by the installer.
Optional equipment
Operator panels can be equipped with a hard drive. It stores all the data of archives, changes in programs, improvements in cutting technology. This option allows you to install an operating system that restores the operation of the machine for a short rewrite. So, when the control board fails, codes in a few minutes are transferred to the memory of the new device. Minimized equipment downtime, the company does not suffer losses in an accident.
CNC metalworking machines are equipped with Wi-Fi transmitters, which provides wireless transmission of the status of lines per hundred meters. The server collects results about the finished product. According to managers, such a revision helps to monitor the state of the production process without leaving the office.
Manufacturer Comparison
CNC machines for metalworking of Russian production do not differ in quality and reliability from machines of Western competitors. The software is more accessible due to its free download on Internet services. Western companies are still leading due to the productivity of management centers. Designers “hone" equipment for the needs of technology in an operational manner.
The leading design bureaus founded dozens of years ago. A team of professionals is able to update machine versions quarterly. Russian counterparts appear much later. But due to the low cost of installations, demand is always present.
Table types
Simple and inexpensive desktop CNC machines for metalworking have gained popularity. Training, the production of small parts, or the need to frequently change the installation location are the main goals of acquiring such models. Compact systems are bought by manufacturers of printed circuit boards, parts for electronics.
CNC machines combine two beneficial factors:
- Low cost.
- Reliability and long-term operation without stops.
Widely used in the technology of cutting sheet materials. The machines are powered by a 220 V network, which makes it possible to place a working unit in garage conditions.
Machine classification
CNC machines for metal processing are divided by size, purpose, type of cutting, control method. Each type takes into account the particular production. So, pipe parts require several types of machines. At one enterprise, whole lines of systems are concentrated, stretching over hundreds of meters.
There are several types of machines :
- milling;
- engraving;
- turning;
- grinding;
- bending and pressing equipment.
By design, they are divided into the following types:
- portal systems;
- vertical
- horizontal.
Machines often buy multi-axis. According to manufacturers, even for the manufacture of simple products, at least two planes of movement of 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 the minimum time to complete an order. No extra effort is required for readjustment. The basic technological programs are stored in the database, it is enough to load a three-dimensional model of the part from a portable medium.
Final products are controlled by the Department of Quality Control. Specialists analyze surfaces using modern equipment. The accuracy of the manufactured parts allows companies to take orders from the military and the space department. On CNC systems, workpieces are produced in 5D planes due to the additional axes of movement of the spindle assembly. According to manufacturers, with this opportunity it turns out to work out all the technological holes in one cutting cycle.
