‍When engraving curved surfaces, laser internal engraving machines generally use auxiliary systems, such as rotating aids, so that cylinders like bamboo tubes, wine bottles, bird cages, etc. can be engraved. In addition, there is a kind of irregular surface, uneven surface, you can choose the laser head that can automatically adjust the focus to work. Now manufacturers of internal laser engraving machines have been able to produce laser heads that focus on metal and non-metal materials. This makes surface carving possible.‍

The internal laser engraving machine is a laser equipment used for internal engraving of crystal handicrafts, etc. It can realize three-dimensional engraving. It is realized by combining the principle of galvanometer and Z-axis mechanical movement.

Laser engraving machine, generally flat engraving, such as leather, offset plate for printing, etc., uses the external xy operating mechanism to drive the laser machine for engraving operations.

The laser marking machine is a marking principle in which a computer controls a galvanometer and drives a laser beam to move in the XY direction to achieve light engraving on the surface of an object.
