Cylindrical grinding wheels
CYLINDRICAL GRINDING WHEELS (FOR GRINDING INTERNAL CYLINDRICALS, GRINDING EXTERNAL CYLINDRICALS AND CENTERLESS GRINDING)
Cylindrical grinding wheels: also available microporous and in the finest grit sizes depending on the application
Cylindrical grinding wheels are manufactured for the different grinding process variants: external cylindrical grinding between centers, centerless grinding in plunge grinding and step grinding, as well as internal cylindrical grinding. We manufacture the grinding wheels individually for your grinding task. The wheel specification depends on your individual process parameters.
With our external cylindrical grinding wheels, we can achieve significant increases in your process performance 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 sharp cutting edges are constantly created by micro-grooves, 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. Grinding wheels are pressed in widths up to 250 mm with intermediate compression. Grinding wheels in larger widths are manufactured as sets, if necessary they are also cut obliquely.
Cylindrical grinding offers high productivity for demanding grinding tasks
Internal cylindrical grinding is mainly used for cylindrical or tapered holes, in which cross feed and plunge cut (with radial feed) are distinguished. The contact area between the grinding wheel and the workpiece is considerably larger in internal cylindrical grinding compared to external cylindrical grinding. Grinding wheels must allow cold grinding with high cutting performance at the same time.

In external cylindrical grinding, rotationally symmetrical workpieces are mounted on one side only or between centers. Depending on the feed rate, the grinding wheel works the workpiece longitudinally on the circumference (cross feed) or the grinding wheel is fed at one point radially into the workpiece until the final dimension is reached during plunge grinding (advance by immersion) ).
In centerless grinding, the cylindrical workpiece is not mounted but supported by a support sheet and guided between the grinding wheel and a gauge wheel. Centerless grinding allows large production quantities with short cycle times at the same time. A distinction is made between two variants: centerless continuous feed grinding and centerless plunge-cut grinding (or feed grinding).
