Amada Machine Tool America’s DV-7M is a modular machine featuring digital inspection, seven control axes and autoloading for both workpieces and grinding wheels. The modular machine automates grinding of the most complex and subtle tool profiles, moving, positioning and loading without human intervention or hesitation.
The grinder is built on a vibration-damping polymer/mineral base, with active cooling, hydrostatic ways, linear motors and optional, modular tilt/swing/rotate machine elements for additional axes of simultaneous control. The range of possible workpieces extends from form-cutting tools to gear hobs; from cylindrical crush rolls to punches and dies. The machine can profile grind, creep grind, or cylindrical grind, with complex relief angles including logarithmic relief for hobs and other complex cutting tools. It can handle a variety of workpiece materials including tool steel, graphite, copper, carbides and ceramics. The machine is designed to use both CBN abrasive and diamond grinding wheels.
A Fanuc 31 i-Model A (Panel i) provides control and CAM functions. After downloading a CAD file, the operator applies reliefs and related geometry to the basic part profile, using a Windows-interface, built-in CAM program at the machine tool CNC. The machine’s vision system compares downloaded CAD files with the actual part profile, sets the swiveling wheel pivot point to the workpiece edge and then enables in-machine digital inspection of all components. As it is grinding, the system identifies departures from the nominal profile at high magnification and with digital precision, enabling wheel-wear compensation.
