2 SIMPLY LXIBL US ADVANTAGS Precise grinding with corundum lexibility with external and internal grinding spindles Rugged machine bed with full-protection hood Hydrostatic guide of X and Z-axis CNC control system with user-friendly interface APPLICATION XAMPLS The versatile grinding machines of the LXA series are ideal for the flexible processing of different grinding assignments on a single workpiece. The LXA is capable of the ultra-precise execution of up to three grinding assignments with minimal retooling time. Whether internal or external grinding and even thread grinding, its modular design makes this conventional, robust grinding machine ideal for small and medium-sized production runs.
