Milling, routing and engraving are popular methods for making billboards, inscriptions and 3D decorations, but they also play a role in wood, metal and plastic processing. The Coner CNC routers (large-area milling machines) allow the milling of inscriptions, edge-lighting boards and reliefs from plexiglass, wood and soft metal. Still, their more robust types also represent professional quality and excellent value for money in industrial plastic, hardwood and non-ferrous metal processing. We have 3-axis and 4-axis CNC routers to form polystyrene foams.
