Diameter-to-Diameter Roll Marking Machines range in size from 14 to 81-in. in length and from 3 to 8-1/2-in. in diameter, and can mark up to 55 characters per line in either a 1/4 or 5/16-in. character size. They also offer cycle times ranging from 7 to 20 seconds, depending on the number of characters to be marked.


Servo Motors to provide faster marking times and more precise positioning. This includes the ability to mark one portion of the complete tooling holder. The servo motors can control the motion to limit the portion of the stamp holder in contact with the part. This speeds up the complete marking cycle and removes the requirement of carry dots and background marking. A laser alignment projection system that takes the guesswork out of the setup process. The laser light identifies exactly where the marking will be on the part.


CMT has also incorporated the latest technology in light screens using an area guard. This electric fence offers a higher level of safety and helps to ensure that the operator is not injured during the movement of the marking system, while at the same time reducing mechanical guarding that obstructs loading and unloading and reduces cycle time. The upgrades offer improved cycle time, and easier set-up, while reducing the need for the secondary marking of serial numbers or tare weights. The new design also improves safety and allows for more complex operations to be completed. 

  • Concave numbering heads for serial numbering.
  • Built-in 2-in. stroke ejection motion to facilitate unloading.
  • Upgraded PLC controls that can be integrated with the production MES system for part tracking and traceability.
  • Random part numbering from a tare weight scale or MES system.
