The mechanical engraving machine contacts the material through the tool, and the depth can be set according to the needs; the laser engraving machine is a non-contact processing surface, which mainly relies on the light emitted by the energy laser tube, and is processed after focusing. In addition, there are some differences between the two, as follows:
First, the precision of the laser machine is higher than that of the mechanical machine, because the beam diameter is small, and the knife of the mechanical machine has a certain width;
Secondly, when processing metal materials, the engraving machine can engrave the corresponding depth, while the laser machine can only engrave a shallow point on the metal surface.
The third is material fixation. The laser machine does not touch the material and requires no fixing steps. Machining is in contact with the tool, and the material needs to be firmly fixed.
But some materials can only be achieved by laser engraving machines, such as cutting flexible materials such as paper, leather, cloth, etc.
