Scribe, stylus and dot-peening marking techniques
Scribe, stylus, dot-peening, Data matrix and vibro-peening processes permanently mark workpieces made from solid materials like e.g. aluminum, magnesium (machined and non-machined), steel, stainless steel, plastics, cast iron. These marking techniques are used for flexible, rapid marking with alphanumeric characters, logos or a 2D code. The marking process results in a permanent, 'document-type' marking.
Scribing / stylus marking technology provides the advantages of high flexibility for the stamped texts, character heights and widths, and stamping depth. Because of the low force needed, solid, hollow and sensitive parts can be also stamped. Mechanical tolerance compensation makes marking possible even on sloped and curved surfaces.
- User-adjustable character height and width
- User-adjustable stamping depths
- Different character sets / special characters
- Low noise level (scribing)
- Minimum effect of force
- Displacement process means no material is removed
- Cost effective standard systems
Description of marking processes
In the case of scribing, a diamond or carbide tip is pressed into the surface of the workpiece and then drawn through the material without hardly any swarf forming.
In stylus marking, a carbide marking needle impacts the surface of the workpiece at a high frequency.
In the case of dot-peening, DataMatrix and vibro-peening, a carbide tip impacts the surface of the workpiece at a high rate. The “crater dots” that are thereby formed give a legible character and/or a data matrix code.
