Loops

Where the tightest tolerances and finest surfaces are required, there is no getting around grinding – it produces fits and qualities that other methods cannot achieve.

During grinding, a rotating grinding wheel with a multitude of geometrically undefined cutting edges removes minuscule amounts of material. This achieves micrometer-level dimensional accuracy and surfaces with very low surface roughness – frequently as finishing work following turning or milling, especially in the case of hardened materials.

The most important grinding processes

• External cylindrical grinding for cylindrical clearance fits with the tightest diameter tolerances
• Centreless grinding for the cost-effective machining of large quantities of rotationally symmetrical parts
• Surface grinding for flat surfaces with high parallelism and surface quality
• inner loops for precise drilling and internal contours

Loops as a quality feature

Particularly with implant components and highly stressed precision parts, the surface quality determines function and service life. By combining grinding with subsequent finishing processes such as honing and lapping, surfaces can be achieved that meet the highest requirements.
