In the USA, Romi offers three models, the D 800, the D 1000, and the D 1250. All three are equipped with big-bore 40-taper direct drive spindles with speeds of 10,000 or 15,000 rpm. Direct drive is low maintenance and improves accuracy and repeatability, while the big-bore 40-taper increases stiffness and allows increased depth of cut during machining.
