Air powered marking tools.
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.

Q: When installing the CMT Retro Fit valve pack, I have a question on the operation. I see that the shop air goes into the FRL. When the Solenoid is used it opens and closes the valve. Within this step, I am confused where the timer comes into play. A: You give it Read more…
Q: We are currently using your Double actioning 8 Ton stamper, to stamp stainless steel fittings. When using the stamper (in a automated process), we are experiencing “Double Stamping” which is making the impression hard to read. We are wondering how we can prevent this. A: Thanks for contacting our on-line help Read more…
