Cylindrical grinding wheels (for internal cylindrical grinding, external cylindrical grinding and centerless grinding)
Cylindrical grinding wheels from Zische – also available microporous and in finest grain sizes depending on the application
Cylindrical grinding wheels are manufactured for the different grinding process variants: external cylindrical grinding between centres, centerless grinding in plunge grinding and through-feed grinding as well as internal cylindrical grinding. We manufacture the grinding wheels individually for your grinding task. The specification of the grinding wheel depends on your individual the process parameters.
With our external cylindrical grinding wheels, we can achieve significant performance increases in your process compared to conventional fine corundum grinding wheels by using sintered corundum grinding wheels (Sol-Gel-Corundum / 3M Cubitron™). The sintered corundum abrasive grain has special self-sharpening properties. During the grinding process, new and sharp cutting edges are constantly created by micro-splitting, which ensures particularly good stock removal.
Centerless grinding wheels are particularly wide and therefore require a carefully controlled pressing process.
Our internal cylindrical grinding wheels are designed with specially developed bond types for this purpose. Depending on the application, we also manufacture our cylindrical grinding wheels in microporous and multi-layer grit sizes. The grinding wheels are pressed in widths up to 250 mm with in-between compression. Grinding wheels in larger widths are manufactured as sets, if necessary also obliquely cut.
Cylindrical grinding offers high productivity for demanding grinding tasks
Internal cylindrical grinding is mainly used for cylindrical or tapered bores, whereby traverse feed and plunge-cut (with radial feed) are distinguished. The contact zone between grinding wheel and workpiece is considerably larger in internal cylindrical grinding compared to external cylindrical grinding. The grinding wheels should allow cool grinding with high cutting performance at the same time.

In external cylindrical grinding, the rotationally symmetric workpieces are mounted either on one side only or between centres. Depending on the feed rate, the grinding wheel works the workpiece either longitudinally on the circumference (traverse feed) or the grinding wheel is fed at one point radially to the workpiece until the finished dimension is reached during plunge-cut grinding (plunge-cut feed).
In centerless grinding, the cylindrical workpiece is not mounted but supported by a work rest blade and guided between the grinding wheel and a regulating wheel. Centerless grinding enables high output quantities with short cycle times at the same time. A distinction is made between two variants: centerless through-feed grinding and centerless plunge-cut grinding (or in-feed grinding).
