Tombstones of all sizes

We see tombstones as a simplified version of automation. With that said, we designed tombstones for all sizes and types of cnc machines. Our original designs were built for small and medium 4th axis machines. The line has quickly grown to encompass vertical and horizontals up to 500mm.
