Vitrified bonds are usually used for this special type of grinding wheels. Depending on the grinding operation, the grinding wheel for bearing seats can be composed of one single layer or of three layers, in case the shoulders and the bearing seat are to be ground in one passage. We are able to manufacture these multi-layered grinding wheels very precisely. Due to the three-layered version, the durability of your crankshaft grinding wheel is increased thanks to the enhanced stability. The low manufacturing tolerances of the motor manufacturers bear witness to our know-how.

We manufacture our polishing rolls for the treatment of leather and leather-like materials. Our polishing rolls are also very well suited for the shaping of such materials. Even unusual sizes can be handled by our company without any problems. An optional metal core provides our polishing rolls with high stability and above-average durability. See for yourself our very flexible product specifications - which are exactly designed for industrial leather processing. NAXOS-DISKUS offers you products which enable you to reach new targets when it comes to cycle time design and workmanship

One of our numerous special fields of work is the manufacture of grinding wheels with a diameter of up to 1650 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.

Gear grinding wheels are used for grinding toothed wheels and tooth flanks. With regard to their specification and their profile, our gear grinding wheels are designed to precisely meet the requirements of the work piece to be ground. If desired, we can provide the gear grinding wheels with a finished profile prior to delivery. The profile of the so-called grinding worms is identical with that of the work piece, and a linear contact takes place across the entire width of the toothing. Due to our cooperation with machine manufacturers (e.g. Prawema), we can always keep you up to date with regard to gearing technology.

Nurit rollers or also yarn guide pulleys are an indispensable aid for the textile industry. The thread which is partially immersed into coolant is optimally moistened and guided, even at high peripheral speeds. Excellent, heat-absorbing properties and extremely precise workmanship support the faultless manufacture and processing of textile threads. Due to the excellent capacity to absorb coolants, you no longer need to worry about faults or downtimes in the manufacturing process. Moreover, we would be pleased to configure specific Nurit rollers according to your individual requirements.

The grinding segments manufactured by our company are available in all imaginable shapes and sizes, and with all bondings and grain types you can think of. One main field of application of grinding segments is the use on a grinding wheel. The grinding segments can be manufactured with a base body (foot) onto which the grinding segments can be optimally mounted. With these grinding segments, even older machine types can be updated to become state-of-the-art grinding technology. Since the segments are machined in a set, we can guarantee an ideal concentricity of the segments. We are your partner in state-of-the-art technologies and also when it comes to the knowledge of well-proven methods.

Our regular and special fused aluminium oxides which are especially designed for surface treatment are suitable for the use in bonded abrasive bodies as well as for the abrasive blasting of workpieces. Due to their high purity and abrasion resistance, excellent surfaces are obtained by the abrasive blasting process. If desired, we can also supply you with very homogeneous mixed corundum which is prepared in our mixing units. Extensive storage capacity ensures prompt delivery of individual quantities. The chemically neutral blasting abrasives made by NAXOS-DISKUS are characterized by high purity, and can be processed without any health risk. They are perfectly suitable for matting, deburring, blast cleaning and shot peening
