The ergonomics of the KELLENBERGER 1000 grinder allow for maximum visibility of the grinding process through premium laminated safety glass. The machine is centrally arranged and every interface is optimized for complete user control, input, and comfort. The KELLENBERGER 1000 grinding machine is housed in a fully enclosed, three millimeter-thick case that facilitates internal grinding wheels of up to Ø 125 mm.

Applications:

Wafer production in the semiconductor industry
Capto grinding
OD production grinding
Universal ID/OD cylindrical grinding
Additionally, high-tolerance advanced defense manufacturing, next-generation aerospace engineering, and life-saving advancements in the medical industry are just some of the countless applications in which the KELLENBERGER 1000 grinding machine facilitates in large-scale production manufacturing and continued innovation.

The new KELLENBERGER 1000 universal ID/OD grinding machine 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 commissioning times and ensures a compact installation area. Durable hydrostatic guides and energy-efficient concepts guarantee a highly secure capital investment.

The following may be added to the KELLENBERGER 1000 for further increased manufacturing capacity:
