sharp inner corner due to natural tool nose radius breakdown. The tool leaves behind a tiny radius fillet. If a mating component (like a bearing inner ring) features a sharp edge, it will ride up onto that fillet, causing misalignment or assembly gaps. The E0.6x0.2 groove cuts subtly behind the face line, allowing the mating part to seat perfectly flat against the shoulder. Tool Standardization and Cost Savings

= 0.2 mm) : The exact depth the groove cuts below the primary cylindrical diameter. This ultra-shallow relief path avoids compromising the core diameter of small-to-medium shafts. 2. Technical Dimensions and Geometry Cross-Reference

| Test | Method | Acceptance Criterion for Exclusive Grade | | :--- | :--- | :--- | | | XRF per DIN EN ISO 3497 | 5.5–6.5µm total Ni; 0.4–0.8µm Cr. | | Adhesion | Bend test or grid cut (DIN EN ISO 2409) | No flaking or peeling. GT0 classification. | | Porosity | Ferroxyl test (iron substrate) | No blue spots after 2 minutes. | | Corrosion Resistance | Neutral Salt Spray (DIN EN ISO 9227 – NSS) | ≥ 120 hours to red rust (base standard requires 48h).

It is often used when the mating part has a large counterbore or will not contact the shoulder. Dimensional Specifications DIN 509 standards size has the following standard parameters: Applicable Diameter ( Recommended for workpiece diameters ranging from Summary Table E (Undercut for one machining surface) Standard Width ( Workpiece Diameter ( is greater than 10 surface roughness requirements for this undercut size?

) of the groove below the primary surface level, measured in millimeters. Key Specifications for E0.6x0.2

will remain the gold standard for premium decorative chromium coatings for at least the next decade. However, buyers should monitor the transition to CrIII or alternative nanocomposites, as the first movers will gain both a regulatory and a cost advantage.

Executing an E0.6x0.2 undercut flawlessly on a CNC lathe demands high precision and rigid tooling setups: sharp inner corner due to natural tool nose radius breakdown

Used on turned shafts or in bores to allow grinding tools or mating parts to reach the corner. Usage Context Din 509-Relief Grooves | PDF | Machining - Scribd

✅ (under-hood brackets, brake caliper pins) ✅ Marine-grade hardware (stainless steel alternative on a budget) ✅ Fasteners (M4–M12) requiring consistent clamp load ❌ NOT for constant immersion in acids or high-temperature (>120°C) environments

Tight tolerances lead to better performance in machinery, with reduced wobble and friction. Conclusion

The designation DIN 509 E 0,6 x 0,2 refers to a specific type of relief groove (undercut)

This specific form is favored when the material needs to be removed cleanly while maintaining a high-quality surface finish, often found in CNC-turned components. Applications and Industry Usage The DIN 509E06x02 is utilized extensively in:
