Quoted from Lamprey:To his point, he talking about the compressed wood that is as hard as steel. Not some soft plastic.
With something like wood that is compressed and as hard as steel how do they "CNC" that? Do they use water jets or plasma or lasers or something else?
CNC Routers can be used for any material including metal. A quality carbide bit will each most any material. As I used to make the prototype playfields (Long ago) for Williams on a laser the carbon (burnt) edge would never work well for production playfields and a waterjet (which I sell now) would ruin the material faster then it could process it.
