How much does the Studer S33 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from United Grinding (Studer). Configuration moves it a long way.
Overview
The Studer S33 is a CNC cylindrical grinder with a center height of 175 mm (6.9 inch), built in four lengths from 400 mm to 1'600 mm between centers, with an 8 kW (10 hp) wheel spindle and a wheelhead B axis that swivels through 255 °.
The swivel is the feature to understand. A range of 255 ° lets one wheelhead bring different wheels to the part in turn, a straight wheel for diameters and an angled one for shoulders, so several operations are finished in one clamping. The table does not list how many wheels or which spindles the head carries. That is a configuration question to settle with the quotation.
The spindle is the lightest in its group. It is rated 8 kW (10 hp) at up to 3'200 rpm and takes a grinding wheel of up to 508 mm (20 inch) in diameter and 80 mm (3.15 inch) in width. The Studer S31 has the same 370 mm (14.6 inch) X travel and the same 3'200 rpm with 11.5 kW (15.6 hp). The Studer S41 goes further, to 15 kW (20 hp) and 4'500 rpm. For finishing and moderate stock removal 8 kW (10 hp) is adequate, but a wide plunge in hardened steel will be slower here.
Workpieces can be up to 349 mm (13.75 inch) in diameter and 150 kg (330 lbs). Workpiece length is 400 mm / 650 mm / 1'000 mm / 1'600 mm (15.7 inch / 25.6 inch / 39.4 inch / 63 inch), paired with Z travel of 500 mm / 800 mm / 1'150 mm / 1'750 mm (19.7 inch / 31.5 inch / 45.3 inch / 68.9 inch). X travel is 370 mm (14.6 inch) at up to 15'000 mm/min (590 inch/min), and Z moves at up to 20'000 mm/min (787 inch/min).

Frequently Asked Questions
01
It swivels the wheelhead, and its range is 255 °. That allows a wheel to be set at an angle to the part or a second wheel to be turned into position, so diameters, shoulders and tapers can be ground without re-clamping. Studer's table for the S33 does not state which wheel arrangements are available.
02
Workpiece length and distance between centers are 400 mm / 650 mm / 1'000 mm / 1'600 mm (15.7 inch / 25.6 inch / 39.4 inch / 63 inch). Workpiece diameter is up to 349 mm (13.75 inch), center height is 175 mm (6.9 inch) and maximum workpiece weight is 150 kg (330 lbs).
03
Spindle power is 8 kW (10 hp) and maximum spindle speed is 3'200 rpm. The maximum grinding wheel is 508 mm (20 inch) in diameter and 80 mm (3.15 inch) wide. If you need more power on the same travels, the Studer S31 is listed with 11.5 kW (15.6 hp).
04
X travel is 370 mm (14.6 inch) with a maximum travel speed of 15'000 mm/min (590 inch/min). Z travel is 500 mm / 800 mm / 1'150 mm / 1'750 mm (19.7 inch / 31.5 inch / 45.3 inch / 68.9 inch), depending on length, with a maximum travel speed of 20'000 mm/min (787 inch/min).
05
When the part outgrows the S33. The Studer S41 has a 15 kW (20 hp) spindle at up to 4'500 rpm, 350 mm (13.8 inch) of X travel, and Z travel of 1'150 mm / 1'750 mm (45.3 inch / 68.9 inch) only. The S33 remains the choice for shorter work, since it starts at 400 mm (15.7 inch) between centers.
