Hardinge introduced the Voumard® 1000 machine for ID grinding, with hydrostatic guideways standard on all axes.

High-Performance, Economical Universal Machine for ID Grinding

Jan. 23, 2020
The Voumard 1000 machine has hydrostatic guideways as a standard on all axes, provides highest performance across ID grinding applications.

HARDINGE INC. is introducing the Voumard® 1000 Universal CNC internal grinding (IG) machine, offering it as a high-performance, economical grinder for a wide range of universal internal grinding requirements, to obtain fine surface finishes and tight tolerances.

More than 10,000 Voumard brand internal grinding machines have been installed around the world over the past 80 years. The new machine replaces the Voumard 110, Voumard 130, and parts of the Voumard 150 series.  The line is specially designed for machining work pieces with larger diameters and / or lengths. Typical applications are grinding operations on parts for hydraulic components, spindles, bearings, or gears as example.

Voumard 1000 offers "almost infinite configuration options" for a wide range of grinding operations; it is designed  to machine work pieces with a length of 300 mm and 300 mm swing diameter over the table.

Included among its features are:
  Hydrolin® hydrostatic guideways on all axes for precision and productivity, providing damping, stick-slip-free operation, and high rigidity (wraparound guideway), resulting in high surface quality for finished parts, and reliability without any friction loss and wear.
  No coupling joints mean superior positioning accuracy, even with very small diameter grinding operations. The Voumard 1000’s design means fewer corrections, as well as optimal thermodynamics in its direct-drive linear motor system for better cooling management.
  Compact hydrostatic spindle turret configuration for accessibility and availability for parts. The new system offers a hydrostatic B-axis, with benchmarking positioning repeatability.
  Compact “table turret” on the hydrostatic B2 axis can be optionally equipped with a workhead and a high-precision rotation axis (C axis) with direct measuring system and torque motor, enabling maximum roundness and precision in fine adjustments for cylindricity of the inner diameter during grinding. A large selection of clamping devices and steady rests are available, too.
  Compact, ergonomic machine design for better overview during grinding and accessibility for best-in-class tool and workpiece management.
  Fanuc 31i control for improved operator access, fast programming and retooling, even for inexperienced operators. The latest Blue solution software created specifically for the Hardinge grinding product brands will be available on the new Voumard 1000 with object guide for easy operation and short set up times. The Black CAM solution for CAM functionality is ab available option.

“We are introducing a new system that incorporates feedback we received from customers, from the rigid base to the hydrostatic guides in combination with direct drives on all axis, all the way to the new user interface on our controls,” stated Helmut Gaisberger, global director product management of Hardinge Grinding. “The new Voumard 1000 system exceeds the most demanding of today’s grinding requirements. Other than traditional grinding machine designs, the Voumard 1000 offers up to five fully functional CNC axis with outstanding positioning accuracies in the nanometer range, as well as best-in-class tool and work piece management. The new concept substitutes additional movement for dressing and measuring devices.”
