The WOTAN® S3A is the Chameleon among our exter­nal cylin­dri­cal grind­ing machines. With 4 sizes for max­i­mum flex­i­bil­ity in terms of com­po­nent size and space require­ments. With options such as auto­matic work­piece feed­ing, it fits into your pro­duc­tion processes and thanks to the optional inter­nal grind­ing spin­dle, you catch up with our uni­ver­sal cylin­dri­cal grind­ing machines. With a changer sys­tem, you have addi­tional options for closed-door machining.

Of course, we opti­mize every S3A with you for your cur­rent and future grind­ing tasks and sup­port you with our flex­i­ble financ­ing options if required.
