The reason is that they built up a brand with a huge mindshare, by flooding the market 30-40 years ago with fairly decent machines with Mazatrol controls. They haven't been competitive for a long time, and are coasting along on their name.Mazak is one of the very largest MTBs in the world for a reason. When you tour a Mazak plant you will see only Mazak machines making Mazak machines. Plasma, laser, sheet metal forming too. And an Okamoto grinder located where a shim is needed for final adjustment. Things may be different on your side of the pond though.
