The GF501 cutting head features a touch-free, high-power motor for smooth and fast performance. It has Renishaw circular grating for precise control and an AO mirror to focus automatically. The X-Y direction focus is sharp. If it bumps into something, the TRA system stops and repositions it accurately. It also has a brake to protect workpieces during power loss and a lifting system for a wide range. Cooling is efficient with its closed-loop water system.
