KEL-UNIVERSAL for grinding jobs in tool and die maker shops, for the grin-

ding of small batches of components or

of prototype pieces, for maintenance jobs,

laboratories or special machine building

facilities.

Machine base with high static and dyna-

mic 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 high-precision 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.

KEL-UNIVERSAL Wheelhead

High-precision spindle bearings hydrodynamic spindle bearings

axial - radial adjustable clearance

Wheelhead for external, internal and face grinding precision-balanced drive motor

WheelheadThe universal wheelhead U has been de-

signed for OD-, face- and ID-grinding in

a single set-up. Roundness, concentricity

and axial run out values of less than 1 m

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 grin-

ding wheel spindle and the finely balan-

ced motor guarantee excellent surface

quality.

Cross-slide Travel 220 mm Rapid traverse 40 mm combined guide device

the lefthand side for externalcylindrical grinding grinding wheel 400 x 50 x 127 mm

Face grinding configuration with grinding wheel on

righthand side for face grinding grinding wheel 300 x 40 x 127 mm

Cross-slide with built-in rise and fall-mechanism of the wheelhead. The total

wheelslide travel of 220 mm can be ea-

sily adjusted by a few turns of the infeed

handwheel, in its coarse position.

Technical dataThe Kellenberger cockpit combines ease

of use with its ergonomic design. The clear

and unobstructed arrangement of the con-

trols assures an optimal operation-comfort.

The automatic working cycle and the

single lever control are the essential ele-

ments for the easy operating.

Automatic cycle by preselecting of:

infeed rates

Changeover position roughing/finishing

Infeed mode Spark-out

Cut-off

Stock removal on rough grinding

max. 0.9 mm/dia.

Stock removal on finish grinding

max. 0.05 mm/dia.
