external cylindricalinternal cylindricalfor large workpieces

Overview
The RSM C series are precision cylindrical grinding machines engineered for long and heavy workpieces. Suitable for single-part machining and small-series production, the machines include an internal grinding device and a classic robust design with a large machine bed, precision-ground guideways and powerful drives for work spindle, grinding spindle and hydraulic unit.

Highlights

• External and internal cylindrical grinding
• Hydrostatic spindle bearings for high surface quality
• Heavy machine frame for large and heavy workpieces
• Swiveling headstock for conical grinding of short parts
• Integrated rapid feed on X-axis with manual return
• Comprehensive package of standard accessories

Product details

• Large heavy-duty machine bed accommodates workpieces up to 2,000 mm in some configurations and diameters up to 320 mm
