Operation: The marking head automatically moves
down against the piece part, applies controlled
pressure, and rolls from right to left across the work,
producing the highest quality impressions. With
large die space and a hand wheel for fine depth
adjustments when required, a variety of sizes can be
marked.
Marking versatility: Flat stamps or marking rolls
are used to mark round, flat or contoured surfaces.
Construction: Unique, rugged design provides
advantages normally associated only with large,
more expensive machines. “ frame construction,
H”
with open back, makes it easy to accommodate
longer parts. Sturdy, completely enclosed base
reduces space requirements. Hand controls are
within easy reach of the operator. Unit is
pneumatically operated with horizontal and vertical
cylinders in the marking head. (Once part is located,
it remains in a fixed position).
