CNC systems are currently the most widely used control systems for numerically controlled machine tools. These systems integrate control, display, and programming capabilities. They are capable of outputting both pulse-type control signals and I/O signals, and typically support the internationally recognized G-code programming language tailored for CNC machines. These systems offer user-friendly programming, compact size, and high reliability, as their internal components generally comply with industrial-grade standards.
Typical Application Industry: CNC machine tools
Classification of CNC Systems Based on Application
Single-Axis CNC Control System
The STC01Z single-axis CNC system, independently developed by our company to meet market demand, is a cost-effective digital motion control system. It allows users to program freely based on the requirements of specific machining processes, supporting up to 99 programming instructions. The system supports both point-to-point control and velocity control, with a maximum output frequency of 40 kHz, making it especially suitable for stepper drives with microstepping and AC servo drives equipped with electronic gear functions.
Multi-Axis CNC Control System
The Engelhardt control system supports control of 2 to 4 axes.
The D-22 two-axis CNC system for lathes was developed by Engelhardt GmbH of Germany specifically for the Chinese market, in close cooperation with domestic machine tool manufacturers. The operating modes, panel layout, and G-code structure were all tailored to align with local users’ habits and preferences.
This system is powered by a 32-bit high-speed Motorola industrial microprocessor, enhanced with Lattice chips and an expanded bus system, achieving a position control cycle of just 0.1 milliseconds. This significantly improves control precision and is equipped with a dedicated lathe control module.
Key features include a manual pulse generator, stepless speed control, composite cutting cycles, tool nose radius compensation, and lead screw pitch compensation. It provides 18 input circuits and 18 output circuits, which can be freely programmed by the user. The system outputs pulse and direction signals for controlling both stepper and servo motors, and also provides a 0–10V analog voltage output and an encoder input for spindle control.
The F-33 CNC system, also from Engelhardt, is an upgraded version of the D-22, adding a third axis. It can simultaneously control three motors via digital pulse signals and supports circular interpolation. Additionally, it includes stepless spindle speed control, making it ideal for three-axis machining with an additional spindle control—for example, in CNC milling machines.
For systems requiring a rotary axis, Engelhardt offers the F-44 CNC system, which further extends axis control capabilities.
This series of CNC systems has already been successfully implemented in various machining equipment such as CNC lathes, CNC milling machines, and CNC grinding machines.
