Custom CNC Engraving Machines
We design and build custom CNC engraving machines for non-standard workpieces across metal, glass, acrylic, PC and other sheet materials.
- Metal
- Glass
- Acrylic
- PC
- Ceramics
- Composites
KG in model names is a series prefix, not a weight figure — see the product pages for each machine's specifications.
Machine Range
The machines we build
Six engraving platforms, assembled and measured in our own workshop. Working area, accuracy and materials are listed for each one.
Machine structure
- Marble machine base
- Precision-ground ball screws
- Linear guides
Shared across all six platforms
