What is the difference between laser engraving machine and CNC engraving machine? Many friends who want to buy an engraving machine are confused about this. In fact, the generalized CNC engraving machine includes a laser engraving machine, which can be equipped with a laser head for engraving. The laser engraving machine can also be a CNC engraving machine. Therefore, the two are intersected and have an intersection relationship, but there are also many differences. Next, Leapion Laser Sales Manager will share with you the similarities and differences between these two devices.
In fact, both laser engraving machine and CNC engraving machine are controlled by computer numerical control system. First, you need to design the engraving file, then open the file through the software, start the CNC programming, and after the control system receives the control command, the engraving machine starts to work.
Laser engraving machine is a kind of equipment that uses the heat energy of laser to engrave materials. The laser is emitted by the laser and is focused into a high-power density laser beam through the optical path system. The light energy of the laser beam causes the chemical and physical changes of the surface material to engrave traces, or the light energy burns off part of the material to show the patterns and texts that need to be etched.
The CNC engraving machine relies on the high-speed rotating engraving head driven by the motor spindle. Through the cutting tool configured according to the processing material, the processing material fixed on the host table can be cut, and various planes or three-dimensional designs designed in the computer can be engraved. The embossed graphics and text can realize the automatic engraving operation.
Laser engraving machines can be divided into different types of special machines according to their specific uses. The structure of these special machines is roughly the same. For example: the laser source emits the laser, the numerical control system controls the stepping motor, through the laser head, mirror, lens and other optical elements, the focus is moved on the X, Y, Z axis of the machine tool, thereby ablating the material for engraving.
The structure of the CNC engraving machine is relatively simple. It is controlled by the computer numerical control system, so that the engraving machine automatically selects the appropriate engraving tool to engrave on the X, Y, and Z axes of the machine tool.
In addition, the tool of the laser engraving machine is a complete set of optical components. The cutting tools of the CNC engraving machine are engraving knives of various entities.
The diameter of the laser beam is only 0.01mm. The laser beam can be carved and cut smoothly and brightly in the narrow and delicate parts. However, the CNC tool is unable to help, because the diameter of the CNC tool is 20 times larger than the laser beam, so the machining accuracy of the CNC engraving machine is not as good as Laser engraving machine.
The laser speed is fast, the laser is 2.5 times the speed of the CNC engraving machine. Because laser engraving and polishing can be completed at one time, CNC needs to be completed in two. Moreover, the energy consumption of the laser engraving machine is less than that of the CNC engraving machine.
The laser engraving machine is noiseless, pollution-free, and highly efficient; the CNC engraving machine is relatively noisy and pollutes the environment.
The laser engraving machine is non-contact processing and does not need to fix the workpiece; the CNC engraving machine is contact processing, and the workpiece needs to be fixed.
Laser engraving machine can process soft materials, such as cloth, leather, film, etc.; CNC engraving machine cannot process because it cannot fix the workpiece.
The laser engraving machine is more effective when engraving non-metallic thin materials and some materials with high melting point, but it can only be used for flat engraving. Although the shape of CNC engraving machine has certain limitations, it can make three-dimensional finished products such as reliefs.
To sum up, the difference between laser engraving machine and CNC engraving machine is still very big. How to choose the equipment that suits you is a comprehensive consideration based on your own needs and budget. For more professional questions, please contact Leapion Laser directly.
