Precision double-column machine
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.
