DuraDot® CNC Marking Tool

The DuraDot® is a spindle-actuated mechanical dot peen marking attachment for use in CNC machining centers. It creates alphanumeric characters, logos, and much more in precise, low-stress dot patterns.

The DuraDot® easily integrates into vertical or horizontal machining centers, milling machines, and similar CNC machines with rotating spindles. It can be manually loaded or traversed through automatic tool changer processes.

Marking capabilities of the DuraDot® depend only on the capabilities of the machine’s existing engraving or CAD software used. Dot density is adjusted through RPM and feed rate settings.

Marking window sizes are limited only by the machining center itself. The DuraDot® is a cost-effective inline alternative to dot peen marking machines used in secondary processes.

A variety of materials up to 55 Hrc can be marked with the carbide stylus including heavy metals, steel, titanium, aluminum, non-ferrous metals, and plastics.

With the DuraDot® you can complement current machining center processes by adding marking as an additional operation. Using the machine’s existing engraving software, unlike engraving or dot peen, you
can create marks faster. At a given RPM, the number of dots or marks per inch is controlled by the feed rate.

Easy to maintain and minimum wear items with no air or cutting fluids required to operate – only rotary action.
