VOUMARD VM 150

Flexible ID/OD grinding machine for large sized work pieces



GENERAL PROPERTIES

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
