FAQ for air impact markers
Q: Model 288 not returning. A: Haven’t had a non-returning 288 before. Not to say it can’t happen but it would be rare. Given that, the basic operation requires the air to push the piston back and blow out the key way until the rod is all the way home.This Read more…
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 Read more…
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 Read more…
Your Question: We use 1/4” round insert stamps for marking full hard 301 stainless steel. A consultant recommended the use of CPM4 as a stamp material to increase life of stamps. I was wondering material you make our current stamps out of (part# CM7G16)? And if you have an option Read more…
Q: For lubrication normally we use 10W “light” industrial hydraulic oil. This oil type isn’t mentioned in GM specifications. Our question is, which oil you prefer for lubrication of the air impact marker in the attached list? Can we also use the oil “5W/30 Motor Oil” for lubricate the marker? Read more…
Q: Why = does CMT recommend a short pulse on the valve for air impact = markers? A: An air impact marker is designed to provide an = “instantaneous” force. After the force is dissipated in the = initial blow the seals are designed to release air. If the Read more…
Q: At what force does the fron t compression spring of the SLide-A-Mark models 651/751/851 compress? A: 18 lbs
Q: How fast is the cycle time of an air impact marker? A: This is depent on many variables including: Air pressure Distance from the valve Lubrication quality CMT suggests a conservative estimate for an air impact marker cycle time to be 1/2 second per inch of stroke length.
Q: I am going to have 5 of these markers working simultaneously. What would be appropriate valving configuration? Do I need to have separate valve for each marker or should I go with one valve with bigger flow for all of them. Please let me know.
A: Yes you need a separate valve for each of them. Please note that the air requirements for air impact markers are referenced through the following link: http://columbiamt.com/CMT-Impact-Marking/Air-Requirements.html
Q: Every component that we use on all Chrysler projects require an uptime analysis.
What is the MTTR (Mean Time To Repair) and MTBF (Mean Time Between Failure) data for your devices or catalog products?
Part #: CM8X16-P ~ Columbia insert marker & 288SPOB25DNL Columbia marker?
A: These are production dependent.
MTTR for the CM8X16 – is 1-2 minutes. The is a perishable item that can not be repaired but needs to be replaced.
MTBF for the CM8X16 – is 3 months. Life expectancy is dependent on production and environment. Most notable the hardness of the metal being marked
MTTR for the 288 – is 5-10 minutes. Depending on the skill level of the person changing the seals.
MTBF for the 288 – is 3-6 months. Depending on the quality of the air supplied to the marking system and the production rate.
