The Okamoto ACC-DXNC Series is a CNC column-type surface grinding platform for large workpieces that require controlled stock removal, repeatable positioning, and programmable grinding cycles. A.W. Miller Technical Sales supports manufacturers throughout New York, Pennsylvania, Maryland, Delaware, Southern New Jersey, and Quebec with applications engineering, installation, training, and service support.
Its traveling-column construction, fully supported table, Vee-and-flat way arrangement, conversational programming, programmable dressing, and 2-axis simultaneous grinding make it a strong fit when large-part flatness and process repeatability need to be managed without relying on manual infeed decisions.
Applications commonly evaluated for the ACC-DXNC Series include:
Coordinated CNC motion supports more complex surface and form-grinding routines than a conventional automatic surface grinder.
The fully supported table and high-rigidity traveling column are intended to control deflection and tracking on heavier workpieces.
Automatic dressing and dress compensation help maintain wheel geometry as stock is removed across extended cycles.
Plunge, bias-feed, and step-feed strategies allow the cycle to be matched to geometry, stock allowance, and finish requirements.
The DXNC adds CNC control and 2-axis simultaneous grinding capability, making it better suited to programmable multi-step processes and applications that require more coordinated motion.
The platform supports multiple grinding patterns, including plunge, bias-feed, and step-feed grinding. The final cycle should be selected around stock, wheel specification, geometry, and finish target.
The column moves while the workpiece remains supported across the table, helping maintain load support and access as the grinding zone moves across a larger component.
Dressing frequency, depth, compensation, and dresser selection should be tied to wheel type, workpiece material, removal rate, form requirements, and surface-finish target.
Representative parts, workpiece weight and envelope, stock allowance, tolerance and flatness requirements, wheel specification, coolant strategy, dressing requirements, and production volume should be reviewed together.
