KELLENBERGER GRINDING VARIA Cylindrical Grinding Machine Technology and design in perfect harmony

STANDARD FEATURES Machine • The new VARIA from Kellenberger combines functional design with high-precision technology. • Hydrostatic guides guarantee maximum dimensional accuracy in grinding tasks with interpolating axes. • High positioning speeds and accuracies are assured by direct drives for the rotary axes. • Generous X and Z axes strokes in combination with the platform concept for grinding head positions and dressing systems ensure universality and allow application-specific configurations. • The proven integral transportation concept (hook machine) has been retained and reduces machine...

THE NEW UNIVERSALCYLINDRICAL GRINDING MACHINE H KeLLENBERGER The new VARIA from Kellenberger unites functional design with high-precision technology.. Hydrostatics The hydrostatic guideways and the systematic separation of the machine base from heat and vibrationgenerating components guarantee the highest in precision and productivity. All movements in the X and Z axes are practically friction-free at all speeds. Hydrostatic B axis Full-fledged NC axis with pre-tensioned hydrostatic guideway and direct drive. The pre-tensioned hydrostatics are the basis for higher accuracy and better surface...

A SUCCESSFUL CONCEPT EVEN BETTER LARGE WORK SPACE – UNIQUE TABLE CONCEPT HEIDENHAIN GRINDplus 640 / KEL-SOFT The perfectly coordinated interaction between the 3D KELSOFT software and the hardware produces optimal results for out-of-round grinding. The machine table has been considerably extended so it allows unmatched, optimal positioning of the grinding wheel and a larger travel distance, but also many machining options and applicationspecific configurations. FUNCTIONAL MACHINE CASING The increased sheet metal thickness means even more process reliability, allowing larger internal grinding wheel...

WHEELHEAD EXPANSIONMORE THAN 30 VARIATIONS Universal Wheelheads The universal wheelhead makes it possible to cover the different needs of users. In addition to external cylind-rical, face and internal grinding, today there is an increase in demand for the use of 2-3 internal grinding spindles or the option of thread or out-ofround grinding. Grinding in one setting allows shorter throughput times and considerably raises the quality of the workpieces at the same time. Diagonal Wheelheads Diagonal wheelheads offer the option of rough and finish-grinding in one setting. With the additional use of...
