Description
Precision Grinding for Small, Complex Components

The Okamoto HPG-500NCS is a saddle type surface grinder built for small components with demanding dimensional and form requirements. It combines CNC control with high-speed table movement for precision surface and form grinding. The compact work area provides clear access for setup while supporting hardened steel, carbide, tooling, and mold applications. With repeatability down to 0.000004 inch, the HPG-500NCS provides the positioning control needed for tight-tolerance grinding.

 

High-Speed Performance for Short-Stroke Grinding

Short grinding strokes can require fast, controlled table movement to maintain productive cycle times. The HPG-500NCS reaches up to 250 strokes per minute at a 0.5-inch stroke. In addition, double vee ways guide the longitudinal and crossfeed axes for consistent tracking during repeated cycles. It also features Servo-driven Y and Z axes for glass-scale feedback and precise positioning. Together, these features make this CNC saddle grinding solution effective for high-precision, short-stroke production applications.

 
CNC Control for Form Grinding and Repeatable Production

A FANUC 0-iMF CNC with graphical conversational programming gives operators direct control over grinding and dressing cycles. The HPG-500NCS also incorporates a three-point dresser for flat and form dressing. This allows the grinding wheel profile to be maintained as part geometry and production requirements change. For manufacturers comparing Okamoto grinder technology, the HPG-500NCS combines CNC positioning, wheel management, and high-speed operation in one saddle-type platform.
