Applications & Suitable Industries

Used STUDER S33 CNC cylindrical grinder is designed for precision cylindrical grinding of small and medium-sized components and is suitable for individual parts, small batches and production environments.

Typical applications include:

Precision shaft grinding – motor shafts, transmission shafts, pump shafts and stepped shafts.
Spindle manufacturing – machine tool spindles and other high-precision rotating components.
Bearing component grinding – bearing journals, seating surfaces and precision cylindrical sections.
Automotive components – transmission parts, drive components and precision shaft-type parts.
Aerospace components – high-precision cylindrical parts requiring tight dimensional control.
Hydraulic components – piston rods, valve components and precision cylindrical surfaces.
Tool and mold manufacturing – precision tooling, arbors, mandrels and related components.
General precision engineering – external cylindrical, shoulder and complex cylindrical grinding operations.

Its universal grinding configuration makes the STUDER S33 particularly suitable for manufacturers that process multiple part types rather than relying on a dedicated grinder for only one component.

STUDER describes the S33 as suitable for individual, small-batch and volume production, with complex workpiece geometries capable of being processed in a single clamping depending on machine configuration.
