Making the most of your laser engraving is a constant concern to obtain the versatility that a fiber optic engraving machine promises. For this it is necessary to implement new practices that allow you to perform work.  And that distinguish from those offered by the competition.

Engraving on cylindrical objects with a laser engraving for metal is certainly something that can help you create new and innovative products. To achieve that we give you the best advice. But to be able to delve deeper into the subject it is necessary to underst. And how a machine works by fiber optic engraving:

Fiber laser engraving is an unconventional thermal process. This engraving process does not generate chip or waste since the removal of the material is given by the vaporization of it. Because a large amount of energy is concentrated at specific points which causes the removal of the material.

The fiber optic laser equipment for laser engraving contains MOPA technology (Master Oscillator Power Amplifier). This equipment generates a laser beam from a resonator, which allows us to engrave not only on metals but also on polymers. And offers the possibility of faster engraving compared to other technologies.

The advantages of laser fiber engraving equipment are as follows:

-Low or almost no maintenance costs.

-Long life of the resonator (100,000 hours).

-Short engraving time.

-Generation of colors in some metals such as aluminum or titanium.

-Homogeneous and high quality engraving.



Fiber optic engraving machines can use not only in flat materials but also in cylindrical elements. To make a laser engraving on any material we use a focal length, which goes from the lens of the equipment to the material to be recorded.

In flat materials there is no problem with this focal distance. However with cylindrical surfaces we have a variation of this distance depending on the distance in the curve of the cylinder that you want to engrave. In these cases there is an accessory called roto-engraving. This device is a Chuck which allows us to hold the cylindrical piece by means of jaws.

This device automatically adapts the designs to the curved surface of the part. And automatically compensates for the focal length of this element in addition to controlling the rotation speed of the cylinder (previously configured) to have a uniform. And quality laser engraving on the surface to engrave.

3 tips to record cylindrical elements.

1. Find the right focal length

The focal length allows us to have an optimal laser engraving point. If this distance varies to a lesser or greater extent. The quality of engraving will not be good or even the material to work cannot record. The use of rotogravure equipment recommend to automatically compensate for the curvature of the cylinders.


Keep in mind that the handling of the engraving parameters will allow you to have different results in the same material. From having a high engraving speed to making a deep and well defined laser engraving. Therefore, recommend to test modifying these parameters to know what your equipment is capable of.


Before working on your product, perform tests, this will allow you to have your equipment ready to record with the quality you want. And have no errors in your final product.
These are some of the important points that you should take into account once you want to expand your catalog. Engraving on cylindrical objects with a fiber optic engraving machine will certainly help you position yourself above the competition by exploiting 100% the versatility of your machine.
