Understand the main structure of CNC engraving machines

1、 Overall structure
CNC engraving machines can be divided into two parts: mechanical structure and CNC system. The mechanical structure consists of the main components of the machine tool, cutting accessories, and transmission mechanism, while the numerical control system consists of a computer, digital controller, and control software.
1. Main components of the machine tool: The main components of the CNC engraving machine include the bed, column, crossbeam, worktable, spindle, and tool magazine. The structure of the main components of different types of CNC engraving machines is also different.
2. Cutting accessories: Cutting accessories include cutting tools, fixtures, tool holders, etc., which affect the machining accuracy and efficiency of the product.
3. Transmission mechanism: The transmission mechanism is mainly composed of servo motors and gear transmission.
2、 Numerical Control System
The numerical control system consists of a computer, a digital controller, and control software. As the core of CNC engraving machines, computers complete calculations and control, converting mathematical models into machine instructions and sending them to digital controllers. The digital controller converts the received machine instructions into physical quantities such as current and voltage, and controls the servo motor to rotate, thereby driving the moving parts to achieve machining.
3、 Working principle
The working principle of a CNC engraving machine is to process the worktable, spindle, and other components along a specified path under computer control, driven by servo motors. The computer instructions are processed by the numerical control system to achieve the operation of the motor and the movement of the machine. The characteristics of CNC engraving machines are high degree of automation, high precision, fast processing speed, and high repeated processing accuracy.
Summary: The CNC engraving machine is mainly composed of two parts: mechanical structure and CNC system, which are automatically adjusted through computer control. It has a wide range of applications in the handicraft processing and decoration industry, and can meet customers’ requirements for processing efficiency and product accuracy.
