Columbia Marking Tools Inc. has pioneered the application development of many of the marking processes used in manufacturing today, including enhanced versions of dot-peen marking, low-stress dot-peen marking, impact marking, roll marking, laser marking and now scribe marking.

Columbia developed a new C-Series of markers that perform both dot-peen and what is called the “Silent Scribe” CNC marking system. Columbia originally patented programmable CNC scribe marking machine technology in 2005 primarily for standard I-Mark scribe markers for marking 2D Square Dot matrix codes. The marker utilizes an x-y-z axis slide arrangement that is driven through precise ballscrews.

The scribe head, mounted on a platen that is linked to the slides, uses a diamond stylus to quietly scribe text or graphics into hard or soft surfaces producing fully-formed lines, curves, and 2D matrix codes. The control of the head movement is provided by a programmable controller that interfaces with standard Windows-based systems combined with the high-power I-Mark marking system to create the marks and codes. 

Utilizing high-power stylus actuators that operate on relatively low air pressure, the C Series can produce extra deep marks. The ballscrew and linear bearing axis design permits the user to have either a quiet-running servo motor drive that provides high-speed marking capability up to 10 characters per second with 0.005mm positioning accuracy, or a high-performance stepper motor drive that gives 0.02mm repeatability at 5 characters per second. 

The machine can operate as a stand-alone or, because of its compact size, can be easily integrated into an automated production system that use robots, because the marking head is designed to “get out of the way.”
