Din 509e06x02 Exclusive |top| -

"DIN 509" is a multi-faceted standard. The table below clarifies common areas of application.

Modern CNC lathes turn these contours efficiently using specialized copy-turning tools or dedicated plunge inserts. For programmers mapping a Siemens CNC or Fanuc Controller system , the path must accurately trace the 0.6 mm arc while respecting the shallow 0.2 mm penetration depth.

), the E0.6x0.2 profile acts as an for smaller components. It provides just enough clearance for tool escape without dramatically sacrificing the structural cross-section or causing severe fatigue weakness under rotational load. 4. Technical Drawing and CAD Implementation

It is a 0.6 mm wide, 0.2 mm deep flat-bottomed undercut with rounded edges, used primarily to clear the run-out of threads on a precision shaft.

The radius of the cutting insert must be smaller than or equal to the undercut radius ( din 509e06x02 exclusive

For this specific size, the standard typically specifies the following additional dimensions to ensure proper tool clearance: Value (mm) Depth Breadth (Width) Run-out Angle 15° (Standard for Type E) Application Guidelines Workpiece Diameter (

Without a relief groove, a grinding wheel or turning insert cannot physically machine a perfect 90∘90 raised to the composed with power

According to the standard DIN 509:2006-12 tables, an E 0.6 x 0.2 undercut typically adheres to the following: Value (mm) Description The curvature at the base of the groove. Depth ( ) How deep the tool cuts into the shaft. Width ( ) ~2.0 - 2.4 The total longitudinal width of the groove. Diameter Range

Sharp 90-degree transitions create severe stress concentrations. Under cyclic mechanical loads, these corners act as crack initiation sites, leading to sudden fatigue failure. The 0.6 mm radius transitions the grain structure of the metal smoothly, dispersing stress lines and vastly improving the fatigue life of the shaft.

depth of the groove provides the necessary clearance space. 2. Mitigating Fatigue and Stress Concentrations

used in technical drawings and machining to provide clearance at the transition between a cylindrical surface and a shoulder. Technical Specifications for E 0,6 x 0,2 According to the DIN 509:2006-12 standard , the parameters for this specific undercut are:

In precision grinding (for hydraulic rods, bearing journals, or piston shafts), an undercut is necessary to allow the grinding wheel to traverse the entire length of the cylinder. The 0.2mm depth of the 06X02 cut ensures the wheel touches the entire required surface without the edge of the wheel crashing into the shoulder of the part. For programmers mapping a Siemens CNC or Fanuc

: Without this specific curvature, a sharp corner on a rotating shaft becomes a "stress riser." Under heavy loads, cracks begin at these sharp points. The Type E 0.6mm radius acts like a smooth highway for mechanical stress, allowing forces to flow around the corner instead of snapping the metal.

Used in critical structural fasteners, engine components, or specialized assembly points where high shear stress and vibration are present.
