Surface grinding machine HFS 50100 F NC

for large workpieceswith magnetic clampingtravelling column

Overview
The HFS 50100 F NC is a cross‑bed surface grinder engineered for large, heavy workpieces that require precision flat grinding or preparatory lapping and polishing. The movable-column design provides extended table guidance and optimal load distribution. Switchable automatic/manual modes support sample production, repair work and operator training.
