Internal and external cylindrical grinding

The manufacture of grinding wheels with a diameter of up to 1,600 mm is one of our many specialties. These grinding wheels are used to grind large crankshafts in ship engines, for example. Their gigantic dimensions require a high degree of production specialization. But the larger size doesn’t mean higher tolerances: In fact, the tolerances are proportionally lower and reach a range where the machining process gets very complex. With our XXL external cylindrical grinding wheels and experience of over 150 years in the production of abrasives, we can offer solutions for just about any processing size. 

For this particular application, a distinction is made between feed-through grinding and plunge grinding. Depending on the situation, you can choose between a single-piece and a multi-piece variant. This may improve the handling when changing grinding wheels, depending on the circumstances. Maximum accuracy and precision in the design and manufacture of the transitions of multi-part wheels is particularly important to avoid impressions of the latter on the grinding pattern. We manufacture these areas with different grain sizes and hardnesses in order to ensure a high cutting rate on the infeed side, especially during through-feed grinding, and a good surface quality on the run-out side.

We manufacture grinding segments in all types of shapes, sizes, bonds, and grain types. One of the main ways grinding segments are used is on grinding wheels. We can manufacture the grinding segments with a base (foot), which enables optimal mounting. These segments make it possible to also retrofit older machine types and bring them up to the current state-of-the-art of grinding technology. We can guarantee you a perfect radial run-out through the processing of the segments as a set. 
We are your partner not only for state-of-the-art technologies, but also in terms of best practices know-how.
