Cylindrical grinding
Cylindrical grinding is used when precise diameters and perfect concentricity are required, particularly for rotating components, to prevent vibrations.
Typical applications include shafts, bolts, spindles, grinding mandrels, and axles.
Material is removed uniformly using a grinding wheel, enabling the highest level of dimensional and geometric accuracy down to a few micrometers. Diamond grinding wheels are frequently used, as they deliver stable and reproducible results even on very hard materials. Additionally, radii, recesses, and steps can be ground with precision; both concentric and eccentric machining operations are possible. Both inner and outer diameters can be machined. Modern CNC technology ensures consistent quality from the first to the last component.
Customers benefit from an optimal surface finish that significantly reduces friction and wear at contact points, as well as from high process reliability in both series production and for individual parts.
Flat grinding
Surface grinding focuses on achieving the highest precision and perfect flatness, especially when parallel surfaces or a very high surface finish are required.
The process is ideal for components such as guide rails, contact surfaces, dies, spacer discs, and industrial blades.
The uniform material removal by the grinding wheel allows flat surfaces to be machined with the highest precision. Among other things, diamond grinding wheels are used, which ensure consistent machining quality even with demanding materials. This enables tolerances of just a few micrometers to be achieved across the entire surface.
Customers benefit from perfect fit accuracy and exceptionally smooth surfaces, which enable precise further processing and a long service life for the components.
Coordinate grinding
Coordinate grinding is used when the highest precision is required for complex geometries. Tight tolerances and the precise positioning of internal and detailed contours often pose challenges for conventional methods.
Typical applications include internal contours, small bores, recesses, and the finishing of precision parts.
Material removal is achieved using rotating grinding pins, enabling flexible machining of the finest structures. The process is particularly suitable for hard materials such as cemented carbide. Thanks to freely controllable machining, complex geometries can be reliably produced. Advantages include high flexibility with varying component shapes and consistent process reliability. Additionally, it produces clean surfaces and precise transitions for many precision parts.
Customers benefit from maximum accuracy, repeatability, and cost-effectiveness.
Centerless grinding
Centerless grinding allows for the precise and efficient machining of slender cylindrical parts. This process offers significant advantages, particularly when there are high requirements for diameter, roundness, and surface quality.
The process is suitable for both small and long workpieces, such as shafts, bolts, axles, or guides.
Centerless grinding is performed without centering the workpiece. Instead, the component rests on a support rail and is precisely guided and machined by the grinding and transport wheel. This results in uniform material removal with very high process stability. This special machining technique achieves the highest levels of concentricity and diameter accuracy. At the same time, centerless grinding enables consistent repeatability, which is particularly advantageous in series production.
Customers benefit from consistently high quality across large production volumes, as well as cost-effective and reliable production, even for demanding precision parts.
