Hydrostatic Guideways for High Performance I.D. Grinding

Hardinge Inc. offers the VOUMARD 1000 Universal CNC Internal grinding (IG) machine.

"The VOUMARD 1000 is a high-performance, economical grinder designed for a wide range of universal internal grinding requirements and is engineered to obtain fine surface finishes and tight tolerances," said a company spokesperson. "It offers enhanced precision and performance in an affordable machine designed to optimize production costs when manufacturing high-precision parts for industries ranging from aerospace to medical."

The Voumard line is specifically designed for machining workpieces with larger diameters and/or lengths. Typical applications are grinding operations on parts for hydraulic components, spindles, bearings or gears, for example.

"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," said Helmut Gaisberger, Global Director Product Management of Hardinge Grinding. "The VOUMARD 1000 offers up to five fully functional CNC axes with outstanding positioning accuracies in the nanometer range as well as best-in-class tool and workpiece management. The new concept substitutes additional movement for dressing and measuring devices."

VOUMARD 1000 offers almost infinite configuration options for a wide range of grinding operations. The machine replaces the VOUMARD 110, VOUMARD 130 and parts of the VOUMARD 150 series. It can machine workpieces with a length of 300 mm and 300 mm swing diameter over the table.

VOUMARD 1000 benefits and features:

  • HYDROLIN hydrostatic guideways on all axes provide enhanced precision and productivity. "This provides improved damping, stick-slip-free operation and high rigidity (wraparound guideway), resulting in better surface quality and reliability without any friction loss and wear," said the spokesperson.
  • High-precision accuracy with a fast oscillation for even the smallest diameters enhances productivity.
  • Compact hydrostatic spindle turret configuration offers enhanced accessibility and larger spectrum of parts. The new system features a hydrostatic B-axis with improved positioning repeatability.
  • The table turret on the hydrostatic B2-axis can optionally be equipped with a workhead and a high-precision rotation axis (C-axis) with direct measuring system and torque motor. A large selection of clamping devices and steady rests completes the available options.
  • New compact, ergonomic machine design allows better overview during the grinding process and enhanced accessibility for tool and workpiece management.
  • FANUC 31i control is designed 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 is available on the new VOUMARD 1000 with object guide for easy operation and short set-up times. BLACK CAM Solution for CAM Functionality is optionally available.
