WOTAN® grinding machines – maximum precision for your products

Internal Grinding

Up to 4 diff. spindles + tailstock, opt. tool changer and various dressers: even bores up to 1,200mm and workpieces >1 ton can be machined.

External Grinding

An continously swiveling round table, up to 4 customer-specific grinding wheels, various dressers as well as balancing systems and spark-in control ensure flexibility.

Polygon Grinding

Eccentric bores, grooves in flat surfaces, non-circular grinding, polygon grinding, multiple edges grinding? No problem with our innovative machines and the WoP software.

Form Grinding

Grind ball shapes, rolling bearing tracks etc.! WOTAN® grinding machines can also master these tasks thanks to a wide range of opportunities for axis interpolation.

Thread Cutting

Internal thread, external thread, grinding or cutting? With our machines almost every thread form can be realized with highest accuracy.


Drilling, reaming, spindling, countersinking and even milling: if necessary, do it all with one clamping using the 5x or 52/72x tool changers on the S3 or S6.


Stationary or rotating, single, in combination or completely individual - with the dressing options of our machines you achieve maximum grinding accuracy at all times.


Perform longitudinal measurement, measure from zero, position or C-axis measurement, inner diameter measurement and much more with the optional integrated measuring systems.
