RUA is a conventional universal grinding machine PLC controlled (interpolation control G-CODE) by electronic encoders that perform multiple working functions. The machine is designed with grinding wheel moves on base by ball screw system and linear guideways. The workpiece is clamped by headstock fixed on the base and tailstock moving on table support by linear guideways. This machine configuration permits to reduce the overall machine dimensions compared to moving table configuration. Base is in composite material specifically designed to obtain the best result between structural deformations and vibration dumping.
