Dot-Peen Marking Process

Industrial marking and part traceability use a variety of marking processes. Dot-Peen is one of the marking methods used. The dot-peen marking process uses a fast actuating stylus “hammer” and CNC 2+ axes controls. The “hammer” impacts the part material indenting a small hole or dimple, while the CNC motorized axes moves the “hammer” to draw the characters of the mark. The Dot-Peen marking process with the CNC motorized axis is over 40 years old and with many different manufacturers of the Dot-Peen marking machines there are also many different systems and configurations to choose from. Several factors to consider include motor type and size, pin type and size, axes design, communication, and software controls. Reliability and cost are weighed based on the application requirements.
