The S33 can grind the OD, the face, and an ID in one chucking for some parts. Here shown set up for internal grinding.
has a shoulder probe, and a B axis that automatically rotates the wheelhead around to do different kinds of features—ID grinding, for example. The S33 grinder is equipped with the
latest generation of high-frequency internal grinding spindles. The machine can grind with speeds up to 120,000 rpm, thus allowing the grinding of very small bores.” In the past, Minnesota Grinding probably would have quoted jobs based on running a part on multiple machines. The new Studer S33 with the Fanuc 0i-TD control can do mul- tiple diameters, multiple faces, and shoulders in one setup on a single machine. It has changed the company’s philosophy and opened up other opportunities because of its precision, speed, and flexibility.

Then I flip the shaft around and grind the other shoulder and the three remaining diameters. The diameters are from 1.5" [38 mm] at the largest, and the far ends are about 0.750" [19 mm] with a
