Dot peen marking machine - GIF

[Toolmaker51]

Dot peen markers go for as little as a few hundred bucks; the platen size and work envelope are main cost differences. They'll sit on a table, does need a decent sturdy foundation to deliver consistent impacts. A simple fixture secures part into place and hit go, runs while same operator packages, gets the next queued up on deck, or both.

Dot peen is a result of highly stressed parts exhibiting fractures emanating to and from standard hand stamp markings; whether hit or impressed. They simplify single marking, pairing, identifying set halves, or serialize sequentially items in either mode. The 'Z' is simple as a screw post on the column and controls depth of marks. Terrific for aircraft parts; indelible; great traceability. The non-automated version uses dotted figure hand stamps. BTW, the point is hemispherical, about .015, unlike a punch.

May be toolholder types that'll run in a CNC I think, dependent on bluetooth communication. Unsure how they get air to it and cycle a solenoid, might be electric instead.
