when grinding chucked workpieces
with inside or outside tapers
KEL-UNIVERSAL for grinding jobs in
tool and die maker shops, for the grinding of small batches of components or
of prototype pieces, for maintenance jobs,
laboratories or special machine building
facilities.
Machine base with high static and dynamic rigidity.
Optimal bracing
Generously dimensioned and precision
scraped V- and flat guideways
guarantee a long lifetime of quality
Three point set-up, no special
foundation required
Workhead with its preloaded highprecision roller bearings is designed for
a working capacity of up to max. 130 kg
between centres or of up to 160 Nm for
components taken-up in chucks.
Standard working accuracy
Roundness for chucked work:
Delta R<0.5 µm according to B.S. 3730.
Increased working accuracy
Delta R<0.2 µm according to B.S. 3730.
Accessoires:
Lever-operated clamping attachment
power chuck

The solid tailstock offers many qualities.
Option
Micro-adjustment
Upper table with anti-friction bearing
pivot pin and fine adjustment of table swivel for cylindrical or taper corrections.
Longitudinal adjustment, manual or
hydraulic, with infinitely variable speed
from 0 – 6 m/min
Dwelling times on table-slide reversal
independently adjustable for both
sides
High reversal accuracy of +/- 0.01 mm
Shortest oscillation travel 2.5 mm

Wheelhead
for external, internal and face grinding
precision-balanced drive motor
High-precision spindle bearings
hydrodynamic spindle bearings
axial - radial
adjustable clearance
Cross-slide
Travel 220 mm
Rapid traverse 40 mm
combined guide device
External cylindrical grinding
configuration with grinding wheel on
the lefthand side for external
cylindrical grinding
grinding wheel ø 400 x 50 x 127 mm
Face grinding
configuration with grinding wheel on
righthand side for face grinding
grinding wheel ø 300 x 40 x 127 mm
Wheelhead
The universal wheelhead U has been designed for OD-, face- and ID-grinding in
a single set-up. Roundness, concentricity
and axial run out values of less than 1 µm
can thus be achieved.
Manual swivel on air cushion
Swivel range +5 / -195 degrees
Indexed position every 90 degrees
Manual clamping in any position
Motor output 3.6 kW
Grinding wheel 400 x 50 x 127 mm
The hydrodynamic bearings of the grinding wheel spindle and the finely balanced motor guarantee excellent surface
quality.
Cross-slide with built-in ”rise and fall“mechanism of the wheelhead. The total
wheelslide travel of 220 mm can be easily adjusted by a few turns of the infeed
handwheel, in its coarse position.
Torsion-stiff, direct infeed-mechanism
for cross-slide that moves on a
combined guide device
Preloaded lead screw nut without
backlash
Hydraulic rapid advance and retraction
with adjustable damping in the end
positions

Lateral and angular dressing device
for dressing of the grinding wheels on the
periphery and on both sides
swivel range: 0–90 degrees
for diamond tools with shank Morse taper 0
Internal grinding
ID-grinding attachment with bore 80 mm
for belt-driven grinding spindles.
Belt guard
Manually operated wheel guard
Coolant feed through workhead spindle
Riser blocks
The very rigid machine construction and
the large dimensions of the slide ways allow the high-precision grinding of workpieces with large diameters. To increase the
working range , the center height of 175
mm can be increased to 250 mm by using
riser blocks.
