CNC engraving machines include woodworking engraving machines, stone engraving machines, advertising engraving machines, laser

engraving machines, laser cutting machines, plasma cutting machines and fiber optic cutting machines, etc. They basically have similar

characteristics. From a macro perspective, an engraving machine is composed of a mechanical structure part, a circuit electrical part, 

and a machine tool. These are the hardware parts of the engraving machine. The mechanical geometric part of the engraving machine

consists of the workbench part, the base part, the machine head part and the beam part. The circuit and electrical parts are composed

of power board, keyboard, and computer wiring board. Microscopically speaking, the engraving machine mainly consists of important

components such as bed, spindle motor, frequency converter, motor, driver, reducer, guide rail, and control system.

   How much do you know about the main components of the above engraving machine? The following is a detailed description of these

important components:

1. Lathe bed structure: It can be roughly divided into two types: welded type and cast iron type. The welded bed is flexible, the process is

relatively simple and the price is moderate. The disadvantage is that the stress removal process is more cumbersome. The cast iron bed is

cast and formed in one step and should not be deformed. The disadvantage is that the casting process is cumbersome and expensive.

2. Spindle: divided into air-cooled spindle, water-cooled spindle and tool change spindle. Commonly used spindle powers are 2.2KW, 3KW, 

4.5KW, and 6KW. Spindles with different powers have different rotation speeds. The selection of spindles with suitable power should be

based on the processing materials, shapes, and requirements.

3. Frequency converter: The frequency converter and the spindle must be matched. Only with a good match can the spindle be maximized. 

Currently, commonly used frequency converters in China include Fuling, Best, Rituo, Delta frequency converters, etc.

4. Motor: Generally divided into stepper motors and servo motors. A good horse comes with a good saddle, and servo motors are generally

equipped with high-end models. Stepper brands include motors produced in Changzhou, and servo motor brands include Japan's Yaskawa

and Japan's Panasonic.

5. Driver: Domestic brands include Lesai hybrid servo drive and R&C. Imported brands include Japan's Yaskawa, Delta and Panasonic. The power

of the driver needs to be selected according to the power of the spindle. The power of the driver should not be less than the power of the spindle.

6. Reducer: The function of the reducer is to reduce the speed and increase the torque. Japan's SHIMPO reducer is not only small in size,

space-saving, reliable and durable, and has strong overload capacity, but also has the advantages of high precision and high load-bearing capacity.

7. Guide rail slider: Guide rail and slider are common mechanical transmission devices that rely on friction to achieve movement and transmission

force. In practical applications, square rails are mostly used, and they are divided into 15, 20, 25, 30 and other sizes according to different cross-sections.

8. Control system: Weihong control and DSP handle control are commonly used on the market. Weihong can draw directly on the computer, then

import it into the engraving program and process it directly. The DSP handle must be connected with a U disk. First copy the U disk into the computer

drawing, and then insert the U disk into the handle. The DSP handle is easier to learn and master, and the operation is simpler, but it is slightly inferior

in function and processing.

Through the explanation of the above knowledge, I believe you will have a clear understanding of the various components of the CNC engraving machine.
