Voumard 1000 Universal CNC Internal Grinding Machine

Hardinge Inc. announced the introduction of the Voumard 1000 Universal CNC internal grinding (IG) machine. The new Voumard 1000 offers a high-performance, economical grinder for a wide range of universal internal grinding requirements to obtain fine surface finishes and tight tolerances. Designed and manufactured with Hardinge’s high quality and focus on innovation, the all new Voumard 1000 is a new standard in ID grinding, providing customers with the ultimate combination of precision, performance in an affordable machine designed to optimize production costs when manufacturing high-precision parts for industries ranging from aerospace to medical.

For over 80 years, the Voumard brand has been a global leader in innovative ID/OD grinding with almost 10,000 installed internal grinding machines around the world. Its line, 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.

 “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 new Voumard 1000 system exceed the most demanding of today’s grinding requirements. Other than traditional grinding machine designs, 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 work piece management. The new concept substitutes additional movement for dressing and measuring devices.”

The Voumard 1000 offers almost infinite configuration options for the widest range of grinding operations. The machine replaces the popular Voumard 110, Voumard 130 and parts of the Voumard 150 series. Prepared to machine workpieces with a length of 300mm length and 300mm swing diameter over the table. Customers can now get the following benefits and features:

·         Innovative HYDROLIN hydrostatic guideways provide the highest performance – The Voumard 1000 features the newest generation of hydrostatic guideways on all axis for superb precision and productivity. It provides excellent damping, stick-slip-free operation and high rigidity (wraparound guideway), resulting in outstanding surface quality and more reliability without any friction loss and wear.

 

·         Ultra-precision accuracy with a fast oscillation for even the smallest diameters to enhance productivity The Voumard 1000’s unique design does not have coupling joints to perform without any backlash, offer superior positioning accuracy-less corrections, as well as optimized thermodynamics in its direct drive linear motor system for better cooling management.

·         Unique, compact hydrostatic spindle turret configuration for ideal accessibility and larger spectrum of parts. The new system offers a hydrostatic B-axis, with benchmarking positioning repeatability.

·         Advantages in high precision also in non-round grinding and improved accessibility with compact “table turret” collision-free dressing - 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. Enabling maximum roundness and precision in the fine adjustment of the cylindricity of the inner diameter during cylindrical grinding. A large selection of clamping devices and steady rests completes the available options.

·         New compact, ergonomic machine design for better overview during grinding process 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 setup times. Black CAM Solution for CAM Functionality is available as an option.

Related Glossary Terms

  • backlash

    backlash

    Reaction in dynamic motion systems where potential energy that was created while the object was in motion is released when the object stops. Release of this potential energy or inertia causes the device to quickly snap backward relative to the last direction of motion. Backlash can cause a system’s final resting position to be different from what was intended and from where the control system intended to stop the device.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • computer-aided manufacturing ( CAM)

    computer-aided manufacturing ( CAM)

    Use of computers to control machining and manufacturing processes.

  • cylindrical grinding

    cylindrical grinding

    Grinding operation in which the workpiece is rotated around a fixed axis while the grinding wheel is fed into the outside surface in controlled relation to the axis of rotation. The workpiece is usually cylindrical, but it may be tapered or curvilinear in profile. See centerless grinding; grinding.

  • dressing

    dressing

    Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.

  • grinding

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • grinding machine

    grinding machine

    Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.

  • inner diameter ( ID)

    inner diameter ( ID)

    Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.

  • inner diameter ( ID)2

    inner diameter ( ID)

    Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.

  • linear motor

    linear motor

    Functionally the same as a rotary motor in a machine tool, a linear motor can be thought of as a standard permanent-magnet, rotary-style motor slit axially to the center and then peeled back and laid flat. The major advantage of using a linear motor to drive the axis motion is that it eliminates the inefficiency and mechanical variance caused by the ballscrew assembly system used in most CNC machines.
