Company presentation
DVS Group is composed of a number of experienced machining equipment enterprises and has been committed to the development and application of turning, gear processing and grinding technologies. NAXOS-DISKUS is one of the leading manufacturers of innovative grinding technology products in Western Europe. As a member of DVS Group, we focus on the development and production of grinding tools of various specifications, including standardized products and customized special products. have been working closely with the group’s machine tool brands for many years to jointly develop customized tool solutions suitable for specific machine tools.
NAXOS-DISKUS was founded in 1871 and is located in Butzbach, Hesse, Germany. It has over 150 years of experience in the field of grinding and abrasives. The products mainly include double-sided end face grinding, cylindrical grinding, centerless grinding and gear dressing and other grinding tools. The precision grinding tools produced are widely used in metal processing, automobile, aviation, shipping and other industries. Parts range from 350mm to 1650mm, with a choice of different abrasives, including traditional abrasive grains and ultra-hard cutting materials such as CBN and diamond.
01
Internal and external cylindrical grinding
Products and technologies
Internal and external cylindrical grinding is used to grind the cylindrical surface and shoulder of the workpiece. The workpiece is centrally mounted and rotated by a device called a center drive, and the grinding wheel and workpiece are rotated at different speeds by separate motors. Internal and external cylindrical grinding is one of the most common methods for grinding camshafts and crankshafts. NAXOS-DISKUS offers materials commonly used in coarse grinding, fine grinding and oblique plunge grinding.
1. CBN and diamond cylindrical grinding wheels
High precision, high hardness, high repeatability grinding
Highlights:
The wheels are based on specially coated CBN abrasives and newly developed ceramic and synthetic resin bonds.
CBN grinding wheels can be used to process extremely hard alloys and carbide-containing alloys, as well as tool steel, special steel and other materials.
Diamond grinding wheels have extremely high external hardness and can be used to grind amorphous metallic materials as well as extremely high hardness metallic materials.
2. Crankshaft grinding wheel
High stability, high durability, high precision grinding
Highlights:
Crankshaft grinding wheels generally use vitrified bond.
Different types of grinding wheels are available depending on the type of grinding task: single-layer manufacturing for the bearing seat and three-layer manufacturing for grinding the shaft shoulder and bearing seat in one go.
The three-layer crankshaft grinding wheel has higher stability and longer service life.
Able to meet the strict production tolerance requirements of engine manufacturers and others.
3. Centerless grinding wheel
High stability, high durability, high precision grinding
Highlights:
Centerless grinding involves two different processing techniques: continuous grinding and plunge grinding. Depending on the application, you can choose a single or split wheel to facilitate the loading and unloading operation when replacing the wheel.
Centerless grinding wheels maximize precision and accuracy when designing and manufacturing the transition section of slotted grinding wheels to avoid leaving marks on the workpiece.
By adjusting the particle size and hardness of the abrasive grains in different areas of the grinding wheel, the chip removal rate on the feed side can be increased while ensuring good surface quality on the discharge side.
4. XXL cylindrical grinding wheel
Maximum diameter up to 1600 mm
Highlights:
The maximum diameter can reach 1600mm, which can handle huge crankshafts on marine engines.
The production of large grinding wheels requires a high degree of specialized production capabilities. Dimensions are increased while tolerances are reduced to meet extremely tight tolerance ranges.
02
End of grinding
Products and technologies
End face grinding is to place the workpiece on the end face of the grinding wheel for grinding, and the grinding wheel transmits the grinding force to the end face of the workpiece through rotation. It is suitable for grinding the end faces of workpieces, such as flat and round end faces and other shapes.
1
CBN and diamond side grinding wheels
High precision, high hardness, high repeatability grinding
Highlights:
It adopts ceramic or resin bonded CBN and diamond grinding wheels, which can be used with steel or aluminum substrates to ensure long service life and high processing precision.
Widely used in metal machining and ceramic processing, such as piston ring grinding.

New CoolEdge GrindPro
Double-sided grinding wheel
High stability, low temperature grinding and reduced machine load
Highlights:
The newly developed high-performance resin makes the bonding quantity lower and adjustable. It also makes the grinding wheel full of particles, smooth grinding, easy to dress, and improves wet wear resistance.
The surface precision of double-end grinding can reach µ level, and about 1.6mm of material on the surface of the blank can be removed.
The low temperature grinding performance of CoolEdge GrindPro wheels effectively solves the problem that some special parts cannot be equipped with additional cooling slots or the coolant nozzles cannot reach the optimal position.
Particularly suitable for processing heat-sensitive parts such as ceramic components.

Conventional surface grinding wheel
Superior matching, precision and stability
Highlights:
With long-term cooperation experience with grinding machine tool companies within the group, we can provide the necessary grinding wheels for various applications.
Conventional grinding wheels are used in a wide range of applications including: the automotive industry (from engine cases to connecting rods), the stamping industry, the watch industry (watch cases) and plate grinding sliding.
Conventional grinding wheels provide customers with stable processing quality, improve grinding precision and reduce costs.
03
dressing tool
Products and technologies
Dressing tools can be fine-tuned down to the micron level. In the process of restoring the circumferential profile of the grinding wheel and resetting it, new abrasive cutting edges are exposed, improving the cutting performance of the tool while reducing cutting forces and associated workpiece temperatures during grinding.
Highlights:
After dressing, the wheel is like new (profiling/grinding).
The tool dressing process can be performed before or after initial machining.
Dressing wheels can dress complex wheel profiles as well as simple cylindrical wheels of varying widths.
The cutting process can be automated.
After cutting, stable and high precision processing can be achieved and the scrap rate can be reduced.
Not limited to a single artifact type.
