MODEL 860FM

Columbia Marking Tools has been designing and building roll marking machinery for nearly
50 years. The technology still remains very popular today because a rolling die
has a relatively small point of contact with the part surface to be marked, so
it can be used effectively on tubular and thin-walled types of parts. The
adjustable marking pressure is only a fraction of the pressure that is
typically required by impact or press marking, and the marking speed is far
greater than that of peen or laser markers.

One of the leading industrial heater manufacturers recently purchased a Model 860FM stand-alone, all air-powered,
roll marking machine from Columbia Marking Tools to mark up to forty-eight
1/16-inch characters along the length of various diameter heater tube elements.
Tube diameters are .260, .315 and .475-inches, in lengths from 20 to
144-inches. Tube wall thickness is either .028 or .032-inches. Tubing material
includes stainless steel, Incoloy™ and copper.

The basic design of the machine, Fig. 1, includes a heavy-duty steel weldment base
to which the Standard Model 860 A22 roll marking unit is bolted. This unit has
a minimum marking pressure of 565-lbs and a maximum of 2260-lbs. The unit
features a cast iron framework to which is mounted the 2-inch stroke air-ram
cylinder; a 3-1/2-inch adjustable internal die slide that provides the rolling
action for the round marking tool; and a cast iron, T-slotted, adjustable table
for mounting the various tube fixtures. Fig. 2. the tube manufacturer provided
the outrigger supports for the various tube lengths. Dovetail quick-change (30
seconds or less) tooling is provided for the different roll marking assemblies.
The machine also includes dual, anti-tie down, anti-repeat palm buttons, and a
complete plug-and-play air system package that includes filter, regulator,
pressure gage, lubricator and shut-off/lockout valve.

Depth of marks range from .003 to .008-inches depending on the material being marked.
Production rate for tube elements is 1000 per day. The machine is capable of
marking 600 parts per hour.
