We will be offering this service of 3D Laser Machining and Engraving when
the Machine arrives in Sept. After installation, training and getting the
work that is already lined up for it done, I would anticipate the service
being available mid to late October. This machine will be capable of high
speed 2D or 3D surface engraving on either flat or curved surfaces and will
also come equipped with a 4th axis for the rotation of production fixtures
or to do just plain cylindrical parts.
Best Regards.
