What is the difference between the mechanical engraver and laser engraver
The most widely used equipment in the advertising and woodworking industry is mechanical engraving machines and laser engraving machines. Many people have difficulty distinguishing the two devices accurately. Today, Focuslaser will take you to understand the differences and connections between them.
One of the differences between mechanical engraving machines and laser engraving machines is the way in which engraving is performed. Laser engraving machines adopt laser light sources as engraving energy for engraving. The engraving of the mechanical engraving machine is performed by a metal cutter, and the types and specifications of the cutter are very high.
In addition, there are other aspects in the difference as follows:
1. Engraving fineness
In the fineness of engraving, laser engraving is higher in precision than tool engraving, because the diameter of the laser engraving source is very small, and the tool engraving itself has a certain knife width. Besides the quality of the machine itself, the accuracy requirements of the tool is very high.
2. Engraving material
Selecting on the engraving material, it is difficult to achieve deep engraving on the metal material by laser engraving, and it is only possible to engrave the coating on the metal surface. And the tool engraving machine can do a certain depth of engraving, even cutting
3. Processing conditions
Laser engraving is a non-contact processing object. For planar engraving, there is no need to fix the workpiece. Since the tool engraving is contact-engraving, it is required to fix the workpiece.
4. The service life
The laser tube of the laser engraving machine has a certain life time limit, and the mechanical tool engraving does not have a time limit. However, the tool wear also occurs so it is necessary to replace the tool in the case of severe wear.
5. Environmental protection
For example, in plastic engraving, laser engraving may produce toxic gases. Therefore a specific air purification system is required to discharge the exhaust gas into the air, while the tool engraving machine does not pollute the air.
6. Engraving ability
The ability of laser engraving to engrave photos is better than mechanical engraving machines. It can directly realize to engrave photos in JPG format, but tool carving can’t do.
