One of our numerous special fields of work is the manufacture of grinding wheels with a diameter of up to 1600 mm. Large crankshafts which are incorporated in marine engines are for example ground with these grinding wheels. These enormous dimensions require a high degree of specialization during the manufacture. The tolerances do not increase with the increasing size. On the contrary, they decrease proportionally and reach very demanding ranges. With our XXL external cylindrical grinding wheels, we can realize every desired size with the experience gained from 135 years of abrasive medium manufacture.
