Applications & Suitable Workpieces

Used KELLENBERGER KEL-VARIA RS 225/1000 CNC grinder is suitable for manufacturers that require accurate cylindrical, bore and face grinding on medium-to-long precision components.

Typical applications include precision shafts and spindles, hydraulic components, bearing-related parts, tooling components, transmission parts, machine-tool components, automotive precision parts, aerospace components and general high-precision mechanical parts.

Its 1000 mm grinding length makes it particularly suitable for longer shaft-type workpieces, while the external, internal and face grinding capability can help reduce repeated setups when a component requires multiple grinding operations.

Kellenberger itself describes the KEL-Varia as the predecessor to its current premium K1000 platform and highlights the series' rigidity and stability for high-precision production. Current K1000 technical literature also confirms the use of hydrostatic X/Z guideways and hydrostatic grinding spindle technology.
