The ND300 is a four-axis, CNC-controlled inspection system that can measure gears, splines, worms and gear cutting tools. Using non-contact, linear motor technology and a crash-protected Renishaw scanning probe head, the system measures a variety of critical part features such as profile, helix, pitch, runout, tooth thickness and size, and others per ANSI and ISO geometric standard callouts. The system's Windows-based software includes dialog boxes, menus and single-keystroke and context-sensitive help files. Operators can set up and run the system within minutes, the company says. The ensuing automated inspection process then frees operators to perform other duties. The system has a sturdy granite base and a mechanical design that doesn't require compressed air. It has few moving parts and non-contact axis motion to create smooth operation and reliable results.
