The CNC system is the central component of all CNC equipment, responsible for controlling the movement and positioning of the machine's axes. It receives instructions from machining or motion control programs and processes them to generate precise commands for the machine tool's operation. As a fundamental part of the numerical control system, it typically consists of three key components: the input/output device, the numerical control unit, and the servo drive.
(1) Input/Output Device
The input/output device serves as the interface between the operator and the CNC system. It is used to input programs, control data, machine parameters, and coordinate positions, while also outputting status information. The most basic input/output devices are the keyboard and display. Depending on the system, additional peripherals such as optical readers, tape drives, floppy disk drives, or even computers can be connected to enhance functionality.
(2) Numerical Control Unit
The numerical control unit (NC unit) acts as the brain of the CNC system. It processes the input data using internal logic circuits or software, interpreting commands related to feed rate, direction, and displacement of the machine axes. These commands are generated through interpolation operations and then sent to the servo drive. The NC unit also manages other auxiliary functions, such as spindle speed, tool selection, cooling, and workpiece clamping. These signals are transmitted to external control devices, which process and execute the necessary actions through actuators.
(3) Servo Drive
The servo drive includes the servo amplifier and the actuator, which together ensure accurate movement of the machine axes. Modern CNC machines often use AC servo motors, while high-speed models may employ linear motors. Older systems might still use DC servo motors. The design of the servo amplifier depends on the type of motor used, and they must be matched accordingly to ensure proper performance.
As numerical control technology advances, the complexity and capabilities of CNC systems continue to grow. In addition to the core components, modern systems may include programmable controllers, spindle drives, and measuring devices to enhance precision and flexibility. Some advanced systems even integrate computers as human-machine interfaces, improving user experience and system performance. Ultimately, the composition of a CNC system varies depending on the specific requirements of the machine and the level of control needed. However, the three essential elements—input/output device, numerical control unit, and servo drive—remain at the heart of every CNC system.
Stainless Steel Radiator
Radiators in this case are manufactured with Stainless steel (SS304, SS316 and SS316L).
These radiators are manufactured with both 1mm CRCA sheet and 1.2 mm CRCA sheet as required and centre distance varying from 600 mm to 4000 mm. Stainless steel radiators can be offered with and without paint.
Through the method, the stainless steel plate type radiator for the transformer is simple in structure, free of complex treatment process on the surface of the radiator, not prone to oxidizing and corroding, long in service life, and high in welding strength.
