Studer S41 for sale: universal cylindrical grinding with stable resale value
The S41 is Studer’s high-performance universal cylindrical grinder: CNC B-axis for contour grinding, high rigidity through its swivel-head design, and StuderGuide linear-motor guideways on all axes. In the lineup since 2011 and still part of Studer’s current range. On the used market, an S41 meets a smaller but better-funded buyer pool than the higher-volume universal models S31 and S33.
Buyers are predominantly shops with contour grinding needs — camshafts and crankshafts, bearing raceways, complex rotational parts with multiple diameters and radii in a single setup. Because Studer owners tend to keep their machines longer than average, used S41 supply stays chronically tight and demand correspondingly stable. Unlike milling or turning machines, a cylindrical grinder’s resale value is not primarily driven by control generation but by the mechanical condition of the grinding spindle, guideways and B-axis.

Pricing (as of October 2026)
We have no reliable public price range for the Studer S41: of the Studer listings we reviewed on Maschinensucher in October 2026, only a small minority state a price, and no S41 was among them. Value is set by build year, control generation, grinding spindle condition, B-axis and grinding head equipment. First assessment after receiving your data. The methodology behind our valuation: What is my CNC machine worth?
What determines your S41’s price
- Control generation: current build years run on the C.O.R.E. OS operating system, while traded used machines mostly run on a Fanuc 31i base with StuderWIN/StuderGRIND — both generations are marketable, with the newer variant commanding a premium.
- Grinding spindle condition: the single biggest value driver — a current test report (runout, vibration, temperature) supports the valuation.
- B-axis and grinding head equipment: a working B-axis and additional grinding heads widen the buyer pool to aerospace and bearing manufacturers.
- Dresser and maintenance records: documented diamond dresser condition and Studer-compliant service history noticeably increase buyer confidence.
- Duty profile: an S41 from single-shift operation on precision shaft or camshaft work commands better prices than a machine from continuous three-shift series production.
Typical buyers of a Studer S41
The S41 appeals to buyers with demanding contour grinding needs — aerospace suppliers, bearing manufacturers, specialized camshaft and crankshaft suppliers — who specifically seek out the B-axis and StuderGuide rigidity. Compare all Studer series: Studer brand hub.
How the sale works
The process follows our Studer acquisition process: build year, control version, spindle hours (external and, if applicable, internal grinding tracked separately) and photos are enough for the first assessment. After that: an offer, payment before pickup; we organise disassembly and transport — granite reference surfaces and guideways are secured against impact and moisture in the process.
