Datron Dynamics (Milford, N.H.) has introduced the excelsior EX high-speed CNC-machining center, designed for applications ranging from engraving steel to machining small parts from plastics. Said to be suitable for applications where tight tolerance and accuracy are paramount, the machining center uses extra-low-pitch precision ball screws, resulting in resolution of ±0.00008 inch, an absolute accuracy of ±0.0005 inch and a relative accuracy of ±0.0002 inch. Standard features include a 20-inch/51-cm square machining area, 60,000-rpm spindle, Windows-based controller and software, 5-tool Automatic Tool Management System, tool-length sensor and tool database, and an ethanol-mist coolant system.
