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
