Used Studer Grinding Machines for Sale 27

Studer has been synonymous with precision cylindrical grinding since its founding in Switzerland in 1912, and its machines consistently define the accuracy standard against which all other cylindrical grinders are measured.

The S-series represents the current CNC platform. The S31 serves production grinding with high-speed CBN wheel capability. The S33 is the universal machine handling OD, ID, face, and taper grinding in a single clamping. The S41 addresses large-capacity grinding for long shafts and heavy components. Each machine uses the Granitan mineral-cast machine base that provides superior vibration damping and thermal stability compared to cast iron construction.

The StuderPictogramming software simplifies cycle programming through a graphical interface where operators define grinding operations by selecting pictogram-based building blocks rather than writing conventional CNC code. This programming approach reduces setup time and lowers the skill barrier for complex grinding cycles.

The earlier CNC universal models — RHU, S20, and S30 series — established Studer's reputation and remain active in toolrooms worldwide. These machines offer excellent value on the used market for shops that need Swiss grinding precision at lower cost than current-generation models.

As part of the United Grinding Group (alongside Schaudt, Mikrosa, Mägerle, Blohm, and Jung), Studer benefits from shared technology development and an integrated global service network.

When evaluating used Studer grinders on Exapro, request roundness and surface finish test certificates, verify spindle bearing condition through vibration measurement, check the Granitan or cast iron base for any damage, inspect workhead and tailstock alignment, and confirm that the CNC control system and StuderPictogramming software versions are current.

As part of the United Grinding Group — alongside Schaudt, Mikrosa, Mägerle, Blohm, and Jung — Studer benefits from shared technology development and a globally integrated service network. Spare parts and technical support are available through United Grinding service centres worldwide, providing long-term maintenance assurance for used equipment buyers.

The Granitan mineral-cast machine base used on current and many recent-generation models provides measurably better vibration damping than cast iron construction — typically three to six times higher damping factor. This translates directly into achievable surface finish quality, as vibration from external sources and the grinding process itself is absorbed rather than transmitted to the workpiece. The mineral-cast advantage does not degrade over time.

Transport and installation of precision grinding machines requires vibration-free foundations and stable ambient temperature conditions. Studer machines that have been well-maintained and properly installed at the seller's facility can be expected to deliver similar accuracy at the buyer's site, provided equivalent environmental conditions are established.
