Linear Glass Scale

The base of the machine consists of a stress-relieved welded steel structure, engineered to maximize rigidity while incorporating open areas for efficient chip and coolant flow away from the working environment. The column travels along the top of this machine base on re-circulating crossed roller bearings along the precision ground linear ways, driven by the CNC controlled AC servo motor and precision balls-crew mechanism. The standard feedback system is by servo motor pulse coder, with the option of employing Heidenhain linear glass scales for even higher accuracy and repeatability.
