CNC engraving machine is the product of the combination of CNC technology and engraving process. It mainly controls the work of the engraving machine according to the program code through the CNC system, so as to realize the automation of engraving processing.

What is the composition of CNC engraving machine?

The structure of CNC engraving machine mainly consists of four parts, namely engraving machine tools, engraving control software, computer and electrical control cabinet, and each of them plays an important role. The following is a detailed introduction to their functions.

✔️CNC engraving machine

This is the mechanical equipment part, through which the engraving machining is done.

✔️Engraving control software

It is used to process and interpret the NC processing code generated by the engraving CAD/CAM software, issue processing control commands, and direct the engraving machine to carry out processing actions to complete the product engraving.

✔️Computer

This is the running carrier of the engraving control software, which coordinates and controls each hardware mechanism of the engraving machine.

✔️Electrical control cabinet

This is the signal detection part of the driving of the engraving machine. According to the control instructions sent by the control computer, the engraving machine is directly driven to generate mechanical motion, and various states of the engraving machine are detected, and fed back to the control computer and control software for identification and processing.

What are the advantages of CNC engraving machine?

It has the advantages of high production efficiency, high-precision processing, high yield, strong adaptability, etc., and it can perform relief, flat carving, hollow carving, etc. on wooden doors, furniture, metal, acrylic and other materials.

In addition, the CNC engraving machine has the characteristics of large low-frequency torque, fast speed, stable output, high-performance vector control, fast torque dynamic response, high speed stabilization accuracy, fast deceleration and stop speed, and strong anti-interference ability.

CNC engraving machines can be divided into woodworking engraving machine, stone engraving machine, advertising engraving machine, glass engraving machine, laser engraving machine, plasma engraving machine, laser cutting machine according to different uses.

What are the uses of CNC engraving machine?

✔️Cut and engraved. It uses the cutting method to process the desired pattern on the surface of the material, that is, first decompose and express the pattern into several lines, and then use the laser to cut these lines to obtain the pattern represented by the cutting line.

✔️Concave engraving. Cut off part of the pattern and leave the surface of the material around the part of the pattern. There are two cases here:

The first case is where the cutting force is the same at every point on the pattern. The engraving pattern is mainly reflected in the outline shape.

The second case is based on light-dark distribution and pattern contrast. The "dark" parts of the pattern are cut more, and the "light" parts of the pattern are cut less or less.

The former is suitable for engraving text, animals, plants and other patterns based on appearance, while the latter is more suitable for engraving detailed patterns such as facial expressions of characters.

✔️Convex engraving. Contrary to die engraving, this engraving process only cuts the material around the pattern, with the same cutting force at each point, but the material of the pattern itself is not cut. This engraving method is suitable for the expression of text, graphic outlines, etc. In the latter two engraving methods, the material is removed by cutting a linear groove each time the laser head travels over the cutting face, and then moves a short distance before cutting the next line. Usually the distance between the two grooves is 0.05-0.5mm.

In this way, multiple linear cuts are used for the purpose of removing the area forming material required for both engraving forms. Of course, in the second form of die engraving, the size of the grooves, especially the depth of the grooves, will vary on the same cutting line as needed.

Last few words

Simply put, CNC engraving machines are mainly used for drilling, circuit board engraving, small parts cutting and mold engraving, etc.
