Q: I am using a Modicon M340 controller. I would like to understand how you specify the addressing for the program file selection. Do I create the address in the stamper or are they fixed?

A: It is fixed.  Send over a bitwise value for the binary program selection.  Within our software, you can map witch layout is assigned to witch bit.

Q: There has been a question of whether or not we should be mounting the unit with M10 screws or M12 screws. We are proceeding with M12 screws as I stated in the earlier email below, but the question has been brought up. Please address whether M10 screws or M12 screws to mount your unit.

A: Highlighted in red to make it easier what would fit with what tolerance ( We would recommend a 3/8” or M10)

Drilled mounting holes called out in fractional size 17/32” = .53

This format is common in NFPA series 2A side lug air cylinder mounting where like Parker and others they give you a nominal size of the hole in fraction. We are not an air cylinder but we do use similar ideas to make mounting easy for installers who are familiar with them. As such the 78, 288, 298, as well as the 651/751 & 851 slide-a-mark series come in flange and side lug foot mount options. Below are some normal sizes machinist use when mounting items and choosing bolt sizes in (decimal equivalent).

M10 bolt tight hole 10.5 (.41) Med 11 (.43) Loose 12 (.47) M12 bolt tight hole 13.0 (.51) Med 14 (.55) Loose 15 (.59)

This link below is handy for clearance holes when using metric screw sizes. Note it give you close medium and loose fit.

The link below from Cal Tec is a handy chart, most machinist use something similar. It will give you the bolt body dimensions and closest metric size and the normal clearance hole
sizes.

Q. The model calls out for a 17/32 clearance hole to mount these units. I don’t see
any dowels on the drawings for these units. We are mounting these with M12
Screws, are we required to heel the marking unit due to the force? What is the
preferred method of mounting these units?

A.

• The bolt holes are over sized to help give
  stability so as to have enough thread to avoid loosening from normal machine
  vibration .
• No dowels nor heal blocks are needed.
• Suggest basic machine tool builder practice
  in making sure the marking head is square to the part to be marked surface.
• As you may know the reaction force is
  captivated and is not applied to the body or mounting.
• I have demonstrated this by actually hand
  holding the marker.
• During our leak and fire test which we
  perform on every marker prior to shipping we do not mount it and only set it on
  some location pins and not clamped or bolted.
• This is in part is one of the many simple but
  great features of the slide a mark tool.
• Sometimes “reaction force” not applied
  realized by the force delivering body can be better explained much like a
  hammer blow. In that when a human strikes a object with a typical 16 oz hammer
  (delivering several tons of force) his feet do not lift off the floor.

The 4 most important items covered in the manual catalog and installation diagrams are the following:

1. Proper alignment (stamps and rod are  square to marking surface) Part is solidly backed up.
2. Extremely short (less than 1/10^th of a second) dwell between advance and retract air valving.
3. Sufficient (min 0.8 Cv) flowing air circuit items (FRL & Valve)

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.
