Air Impact Markers Need No Lubrication
Columbia Marking Tools, Chesterfield Twp., MI, offers its Slide-A-Mark marking tools that use a patented, soft-impact marking action to mark metallic or nonmetallic surfaces at low noise levels. The markers are pneumatic units that telescope (or stroke) to the workpiece, preloading the alphanumeric stamp against it. Then they propel the internal hammer, which develops marking force, into the stamp, permanently marking the part. They are used for marking applications including lot numbering, date coding, traceability, inventory and final inspection as well as nonmarking applications such as piercing, staking and seating of products.
With compressed air of variable pressure providing both the advance marking force and retraction for the tool, there are few mechanical parts to maintain.
