The machine the shop uses for high-speed peel grinding is a Studer S41 universal cylindrical grinder. Mr. Maurer says this machine can perform a variety of operations, including ID, OD, cam, thread and out-of-round thread grinding.
Internal grinding is also performed by vitrified CBN grinding wheels. A broad range of spindles designed for 12~60-mm-diameter wheels, as well as arbors for various hole shapes, are available. The photo shown below is a 25-mm-diamter wheel mounted on a 125-mm-long arbor, which is installed in a high-frequency spindle providing 30,000 rpm.
Arbors for Grinding Cones The threaded head on these arbors holds a grinding cone. Spiral-Wound Sanding Roll Arbors The arbor's shank attaches to hand-held drills and die grinders. Threads on the body hold the sanding roll in place. Tight-Grip Spiral-Wound Sanding Roll Arbors
The Art of Grinding. Conventional external grinding HSG external grinding Internal grinding To technologically demanding threads or keyways in difficult machining materials, special grinding machines used to be the first choice. This will now change with the introduction of an A-axis on the STUDER S41 and S22 cylindrical grinding machi-nes.

WEMA's internal grinding machines maximize operating times with more efficient and integrated procedures. A repeatedly allocable tool and workpiece headstock are guided on up to six axes with an accuracy of 0.1 μm.
Thread grinding is an accurate way to produce internal threads and is an effective choice for tight-tolerance parts. A wide range of internal threads, grooves, ball tracks and other forms can be ground on one machine. Typical parts ground on an internal thread grinder include thread gages and nuts for roller, lead and ball screws.
Use these adapters to mount toolroom grinding wheels to most surface grinders. Adapters consist of a hub, nut, and lock washer.. Use the optional wrench to tighten or loosen the adapter nut..
