Sell your Studer S33: a cylindrical grinder in high demand
The S33 is the most-traded universal cylindrical grinder from Fritz Studer AG: external-cylindrical grinding as the base function, optionally extended with an internal grinding head for shafts and bores in a single setup. This combination meets a broad, active buyer base among German mid-sized manufacturers — hydraulics, bearing production, precision machine building.
On the used market the S33 holds up better than average: Studer machines are known for their longevity, and membership in the United Grinding Group secures spare parts supply even for older build years. Selling an S33 means selling a machine with resilient demand.

Pricing (as of October 2026)
We have no reliable public price range for the Studer S33: of the S33 listings we reviewed on Maschinensucher, Exapro and gebrauchtmaschinen.de in October 2026, only one states a price, and a single offer does not allow a range to be derived. Value is set by build year, control generation, grinding spindle condition, internal grinding head and documentation. First assessment after receiving your data. The methodology behind our valuation: What is my CNC machine worth?
What determines your S33’s price
- Grinding spindle condition: a current test protocol (runout, vibration, bearing temperature) supports the valuation — replacing the spindle is a considerable cost.
- Internal grinding head: machines with this option widen the buyer pool to shops that grind shafts and bores in a single setup, and command a noticeable premium.
- Control generation: a Fanuc control with StuderWIN remains solidly tradable but is rated below the current C.O.R.E. OS generation.
- Dresser condition: the diamond dresser shows how precisely the machine still grinds — wear here is a visible pricing argument for buyers.
- Maintenance history: documented oil and lubrication changes per the Studer maintenance schedule build buyer confidence and shorten inspection time before the offer.
Typical buyers of a Studer S33
The S33 is sought above all by suppliers in hydraulics, bearing and shaft production, and precision machine building who need a liquid, well-documented cylindrical grinder in the mid segment — often as an addition to an existing Studer fleet. Compare all Studer series: Studer brand hub.
How the sale works
The process follows our Studer acquisition process: model, build year, spindle hours, control version and photos are enough for the first assessment. After that: offer, payment before pickup; we organise dismantling and transport. Details: How it works.
