New Product Release on heater tube roll marker

NEW COLUMBIA MARKING TOOLS STANDARD MODEL 860FM

ROLL MARKING MACHINE MARKS UP TO 48 CHARACTERS ON

TUBULAR ELEMENTS OF INDUSTRIAL HEATERS

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 860MF 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.
