Flexible ID/OD grinding machine for large sized work pieces


The VOUMARD VM 300 is a universal ID / OD grinding tool specifically designed for machining work pieces with large diameters and / or lengths. The large working space in combination with the extended travelling distance of the spindle head and the optional U-axis provide highest loading capacity and process flexibility. 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 700 x 300 mm
Ø 360 x 1500 mm (with steady rest)
* Depending on Machine Configuration


The VOUMARD VM 300 is the only high precision ID grinding machine in the market providing maximum work piece dimensions of up to 700mm in diameter and 1500mm length. The VM300 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
  • Easy of use – Easy programming with VOUMARD graphical user interface
  • Flexibility – ID/OD grinding with thread, taper, cam, centerless and centered grinding options
  • Modularity – Wide range of machine configurations, options and tools to satisfy all needs
  • Increased availability – Minimum maintenance and reliable components drastically reduce down time loss
  • Time saving – FG-PROG software for off-line programming on an external PC


  • Four position NC indexing spindle turret permits multiple ID/OD grinding operations with different grinding wheels at the same work piece and combines maximum flexibility with highest grinding accuracy
  • Optional U-axis for extended OD grinding range
  • High precision X- and Z-axis with large travel distances for maximum flexibility
  • Manual or numerical controlled B-axis for angular swivel of the workhead for taper grinding and easier access when loading and unloading large work pieces
  • Optional work head spindle indexing (C-axis)
  • Various dressing tools for conventional and CBN grinding wheels, including a radius dresser for high precision grinding of circular profiles
  • Heavy duty work head spindle with a load capacity of up to 500kg


  • Fanuc CNC with proprietary VOUMARD graphical user interface
  • Offline programming tool on external computer minimizes downtime when creating new grinding sequences
  • Remote diagnosis system for quick trouble shooting
