Double-column type CNC surface grinding machine series
Double-column type CNC surface grinding machine series — a proposal for fully automated machining and on-machine measurement of large high-precision components.
Linear motor drives on both sides of the table, combined with a variable hydrostatic slide system on the sliding surfaces, enable high-speed grinding and crowning grinding. An ultra-precision portal-type surface grinder supporting in-machine measurement through precise positioning.

Key features
- Linear motor drive and variable hydrostatic slides on the left and right tables allow left/right table speeds to be freely controlled for 2-axis interpolation from stable low speeds up to 40 m/min
- Wide range of options including crowning, multi-processing, free contour machining, and measurement/correction machining
- The ultra-precision variable hydrostatic slide system minimizes oil-film changes on the guide surface, achieving oil-film thickness variation under 1/7th of conventional hydrostatic guide surfaces while cutting hydrostatic oil consumption to under 1/4 of conventional levels
- Optimized equipment environment supports ultra-precision machining and mirror-finish processing

The ACC-CHiQ series is Okamoto's double-column high-quality precision grinding machine with Okamoto iQ-Control for large components. It meets the very highest requirements in terms of precision found in the manufacture of parts in tool and mould construction, hot-runner technology and punching-die construction. The cross slideways can be adjusted mechanically and can be realigned at any time as needed — the CNC does not need to be compensated, which in turn affords advantages in higher surface quality and smoothness.
With a grinding length of 2 m to 10 m and a cross travel of 1 m to 3.5 m, the Okamoto UDG-NC Series is ideally suited for both toolroom and production use. The robust cast iron construction and hydrostatic slideways together with a moving cross rail ensure long-term precision. The intuitive operation of the controls simplifies usage and increases productivity considerably.
