Internal and External cylindrical grinding wheel
External cylindrical grinding is one of the most common methods used for the grinding of camshafts and crankshafts. Our solutions are best suited for the materials most commonly machined in rough grinding, finishing and angled plunge-cut grinding.
We enable the highest precision for every field of application by individually selecting the structure of each grinding wheel according to the individual specific application of our customers.
External Cylindrical Grinding
It is one of the most common methods used for the grinding of camshafts and crankshafts. Our solutions are best suited for the materials most commonly machined in rough grinding, finishing and angled plunge-cut grinding.
We enable the highest precision for every field of application by individually selecting the structure of each grinding wheel according to the individual specific application of our customers. The manufacture of grinding wheels with a diameter of up to 1,600mm is one of our many specialities. With our XXL external cylindrical grinding wheels and experience of over 150 years of production of abrasives, we can offer solution for just about any processing size.
Centerless Grinding Wheels
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.
Crankshaft Grinding Wheels
This unique type of grinding wheel generally uses ceramic bonds. Depending on the type of grinding task, the grinding wheel for bearing seats can be built up in one layer or, if the shoulders and the bearing seat are to be ground in a single pass, also in three layers. We can manufacture these wheels very precisely in multiple layers. The three-layer design also increases the durability of the crankshaft grinding wheels due to higher stability. The fact that our grinding wheels meet the stringent production tolerances of engine manufacturers, among others, is indicative of their uniqueness and a testament to our proven know-how
Mounted Point – Internal Grinding Wheels
Our mounted points are used for internal cylindrical grinding. These can be made from conventional abrasives as well as CBN mounted points. CBN mounted points yield a longer service life of the grinding tool. The mounted points from NAXOS-DISKUS are extremely reliable under difficult conditions and at high speeds. They are especially useful for use in hard to reach places.
In future, mounted points will be used for time-saving simultaneous grinding in many cases. Once again, you can rely on NAXOS-DISKUS as the manufacturer of every conceivable type of abrasive.
Disc Type Grinding Wheel
In industrial use, surface grinding of workpieces is often a basic requirement, such as for cylinder heads where absolute evenness is critical. This process entails a wide range of variations and possible uses – it is used in the tooling, ceramics, and automotive industries, among others, where cylinder barrels, housings, covers, or cylinder heads are processed to render the sealing surfaces completely flat.
Conventional Disc Grinding Wheels
For conventional disc grinding, we are the original equipment manufacturer for the famous double-disc grinding machines from DISKUS WERKE. Our many years of working with our partner has enabled us to manufacture grinding wheels for every suitable application case. Some of the areas of application for conventional grinding wheels are the automotive industry (from engine blocks to conrods), punching, or grinding skies! What makes our grinding wheels unique is the high and consistent quality and dimensional accuracy with an unbeatable price-performance ratio.
NAXOS-DISKUS can look back on many years of experience in the manufacture of CBN and diamond disc grinding wheels. Our discs are used for many different types of metal and ceramic machining, such as for the grinding of piston rings. These grinding wheels offer a long service life and high dimensional accuracy of the ground workpieces. Our grinding wheels can optionally be covered with a base body made of steel or aluminum. Our ceramic and synthetic resin bonded CBN and diamond disc grinding tools offer complete peace of mind for the future.
CoolEdge GrindPro is the latest innovation in a grinding wheel designed to revolutionise double face grinding. Heat-sensitive workpieces such as ceramic components are workpieces for which CoolEdge GrindPro is particularly suitable. The challenge of double face grinding is that the workpiece must be ground flat to the µ with a high stock removal of up to 1.6 mm. A newly developed, innovative resin ensures a low, adjustable bond quantity. This makes the grinding wheel grain-rich, soft-grinding and excellently dressable. Another plus is the improved wet grinding resistance, which is also due to the newly developed resin. CoodEdge GrindPro stands for “high stability”, “cool grinding” and “lower machine load”, aspects that relate to the machining of materials, especially in the industrial sector.
NAXOS-DISKUS produces grinding segments for a wide range of applications.
The advantage of grinding segments is their ease of installation in the grinding machine. They are also perfect for rough machining to maximize the dimensional and surface properties. One of the possible uses is the grinding of engine blocks. Another example are ball cages that are ground on one side.
CBN and DIA Grinding Tools
In the machining of extremely wear- and abrasion-resistant materials, maximum processing speed and precision are required nowadays. NAXOS-DISKUS has a wide range of tools with diamonds and CBN for the efficient machining of amorphous materials or carbide-containing alloys.
External cylindrical grinding
Our CBN and diamond grinding wheels enable extremely accurate grinding performance with excellent repeatability. Specially coated CBN grit and newly developed ceramic and synthetic resin bonds form the basis for your CBN and diamond grinding wheels from NAXOS-DISKUS. These special CBN grinding products are used for the machining of very hard and carbide-containing alloys. They can also be used for excellent grinding results with materials such as tool steels, specialty steels, and much more. Our diamond grinding wheels feature maximum hardness, which is why they are also suitable for the machining of amorphous and extremely hard materials.

Dressing Tools
Since the introduction of CNC-controlled dressing processes, the number of CBN and diamond form dressing rolls on the market has increased significantly. In working closely with DVS Tooling GmbH and BUDERUS Schleiftechnik GmbH, our goal is to reduce the type diversity in order to achieve more streamlined warehousing and more cost-effective tool production. DVS TECHNOLOGY GROUP thus enables users to make their grinding processes more economical.
Dressing of the grinding wheel enables precise concentricity and a correct geometric shape on the grinding wheel. In addition, dressing is used to profile or calibrate grinding wheels. Dressing also removes impurities from the grinding wheels caused by material abrasion and the blunted abrasive grits, and it lays bare the sharp abrasive grits. This reduces heat generated during the grinding process and keeps the required removal rate constant.
Diamond dressing rollers are available in different designs. While natural diamonds are the norm, industrial diamonds are also used more and more frequently. The materials used are MKD, CVD and PCD. Due to their defined shape, they guarantee constant and reproducible quality over their entire service life. Since the introduction of CNC-controlled dressing processes, there are many CBN and diamond form dressing rolls on the market. In working closely with DVS Tooling GmbH and BUDERUS Schleiftechnik GmbH, NAXOS-DISKUS Schleifmittelwerke GmbH want to reduce the types diversity to a normal level in order to achieve more streamlined warehousing and more cost-effective tool production. DVS TECHNOLOGY GROUP thus enables users to make their grinding processes more economical.
