Sample parts produced for a NY window company. Part is metal cylinder and it got serial number text engraved along the circumference. Laser marking on cylinders, tubes, pipes rings etc needs to be done with rotary too. With rotary part is being spinned by a stepper motor when laser works and in this way printed text or artwork covers whole face of the cylinder wall. LaserCutZ laser engraving machine can do automatic serial numbers or date time stamp for each part we engrave.
