VOUMARD VM 150 - The production cylindrical grinding machine


Flexible ID/OD grinding machine for large sized work pieces


The VOUMARD VM 150 is a multi-purpose tool for ID / OD grinding operations with medium to large sized work pieces in small batches as well as in volume production. While short work pieces can be ground directly when clamped in the chuck, a variety of manual and automatic steady rests is available for grinding operations with long shafts.

Typical applications are grinding operations with parts for:

  • Hydraulic components
  • Spindles
  • Bearings
  • Gears

Maximum Workpiece Dimension*
Ø 500 x 100 mm
Ø 250 x 1400 mm (with steady rest)
* Depending on Machine Configuration


Our best-seller, the well known VM 150, is the versatile machine for medium to large sized work pieces. This machine offers ID grinding combined with OD grinding capabilities as well as a large variety of chuck and dressing options. Every machine bed is still hand scraped enabling our users to reach sub-micron precision and enabling „The Ultimate Touch in Grinding“.

All machines of the VOUMARD Productivity Line can be equipped with an automatic loading system to meet production requirements.

Versatility and simplicity without compromising efficiency

  • Reduced changeover times – Very good accessibility to machining area allows quick tool changing
