VOUMARD VM 300 - The production cylindrical grinding machine

VOUMARD VM 300

Flexible ID/OD grinding machine for large sized work pieces



GENERAL PROPERTIES

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



CUSTOMER BENEFITS

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
