A new standard
The all-new Voumard 1000 is, says Hardinge, “a new standard in ID grinding, providing customers with
the ultimate combination of precision, performance in an affordable machine designed to optimise
production costs”. Specifi cation details are being held back for GrindTec, Augsburg, Germany, 18-21
March, but here’s the early news
The Voumard brand has been a global
leader in innovative ID/OD grinding for
more than 80 years, with almost
10,000 internal grinding machines installed
around the world. Parts having large
diameters and/or lengths have been the
company’s focus, with typical components
taking in, for instance, 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 axes, all the way to the new
user interface on our controls,” explains
Helmut Gaisberger, global director product
management, Hardinge Grinding. “The new
Voumard 1000 system exceeds the most
demanding of today’s grinding requirements.
In contrast to traditional grinding machine
designs, the Voumard 1000 video: https://
is.gd/elemom offers up to ve 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.”
Says Jörg Schulz, manager grinding
technology: “We are all con dent that the
product will bring Voumard back to the top
level of internal grinding machines.”
The machine replaces the Voumard 110,
130 and parts of the 150 series. The new,

linear and two rotary, but up to ve
with C-axis), with the auxiliary axes of
previous designs eliminated. ID
grinding is the Voumard 1000’s
primary goal, but external grinding is
also supported. Part capacity is
300 mm length and 300
mm swing diameter over
the table; internal grinding
length is 200 mm;
external grinding length is
150 mm; part weight is
50 kg at 3,000 rpm or
200 kg at 1,000 rpm;

traverse is 20 m/min; B1-axis rotates 330°
accessibility with a compact ‘table turret’
in 3 sec; B2-axis rotates 225° in 2 sec.
Highlighted features and bene ts are:
Innovative Hydrolin® hydrostatic
guideways, the newest generation of
hydrostatic guideways, on all axis for
“superb precision and productivity” –
Hydrolin is the combination of hydrostatic
guideways combined with linear direct drive.
Excellent damping, stick-slip-free operation
and high rigidity (wrap-around guideway),
deliver 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. Its unique design
does not employ coupling joints, thus
negating backlash and delivering superior
positioning accuracy, as well bene ting from
optimised thermodynamics.
Unique, compact hydrostatic spindle
turret con guration offers ideal
accessibility and allows for a larger
spectrum of parts. The hydrostatic
B1-axis boasts “benchmark positioning
repeatability”.
Advantages in high precision round
and non-round grinding, plus improved
that allows collision-free dressing. Located
on the hydrostatic B2-axis, the table turret
can optionally be equipped with a workhead
and a high precision rotating axis (C-axis)
with direct measuring system and torque
motor. Maximum roundness and precision
via ne adjustment of inner diameter
cylindricity during grinding. A large selection
of clamping devices and steady-rests
completes 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 optimised HMI software
created speci cally for Hardinge grinding
products will be available, offering easy
operation and short
set-up times. And
the ‘Black CAM
Solution for CAM
Functionality’
is optionally
available.
