How much does the Studer S100 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from United Grinding Group. Configuration moves it a long way.
Overview
The Studer S100 is a cylindrical grinder for short, large-diameter work: workpieces up to 550 mm (21.65 inch) long and 420 mm (16.53 inch) in diameter, on a center height of 225 mm (8.86 inch), with a B axis that swivels over -10 – +190 °.
Two rows describe the grinding spindles, and they should be read separately. Maximum spindle speed is 60'000 rpm. The maximum grinding wheel is 400 mm (15.75 inch) in diameter and 40 mm (1.57 inch) wide. No 400 mm (15.75 inch) wheel runs anywhere near that speed, so the speed figure has to belong to a small high-frequency spindle of the kind used in bores, and the wheel size to an external wheel. The table gives no spindle power for either and does not say how many spindles the wheelhead carries, so both belong on the list of questions for the quotation.
A swivel range as wide as -10 – +190 ° is what lets one wheelhead present more than one spindle to the part, and set a wheel at an angle for a taper or a face. The benefit is a bore, a face and an outside diameter finished in one clamping.
X travel is 285 mm (11.22 inch) at up to 10'000 mm/min (394 inch/min). Z travel is 800 mm (31.5 inch) at up to 20'000 mm/min (787 inch/min). Z is well beyond the 550 mm (21.65 inch) workpiece length, which leaves stroke for dressing and for backing a long quill out of a bore.

Strengths & Limitations
Strengths
- Spindle speed listed up to 60'000 rpm, the range that small bore-grinding wheels need
- Takes workpieces up to 420 mm (16.53 inch) in diameter on a 225 mm (8.86 inch) center height
- B axis swivels over -10 – +190 °
- External wheels up to 400 mm (15.75 inch) in diameter and 40 mm (1.57 inch) wide
- Z travel of 800 mm (31.5 inch) at up to 20'000 mm/min (787 inch/min)
Limitations
- Workpiece length is limited to 550 mm (21.65 inch)
- X traverses at 10'000 mm/min (394 inch/min), half the rate of Z
- Maximum grinding wheel width is 40 mm (1.57 inch)
- The table gives no spindle power and no workpiece weight limit

Frequently Asked Questions
01
Workpiece length is up to 550 mm (21.65 inch) and workpiece diameter up to 420 mm (16.53 inch). The center height is 225 mm (8.86 inch). No workpiece weight is listed, so ask for the workhead load rating if the parts are heavy for their size.
02
The two figures describe different spindles. A speed of 60'000 rpm is that of a high-frequency spindle carrying a small wheel, as used in bores. The 400 mm (15.75 inch) by 40 mm (1.57 inch) wheel is an external wheel on a much slower spindle. Studer's table for the S100 does not list the speed of that second spindle or the power of either.
03
X travel is 285 mm (11.22 inch) with a maximum travel speed of 10'000 mm/min (394 inch/min). Z travel is 800 mm (31.5 inch) with a maximum travel speed of 20'000 mm/min (787 inch/min). The B axis has a swiveling range of -10 – +190 °.
04
The Studer S33 has more X travel, 370 mm (14.6 inch), and its spindle is listed at 8 kW (10 hp) and 3'200 rpm. The S100 has 285 mm (11.22 inch) of X, one Z travel of 800 mm (31.5 inch) and a spindle speed of up to 60'000 rpm, which places it with bore and chucking work.
