CMT Eclipse LET-Conveyor Automated Marking Machine

Engineered and Built by Columbia Marking Tools

CMT Eclipse Model LET-Conveyor is a high production automated industrial laser marking machine.

The Machine

LET-Conveyor Automated

Designed for manufacturers that need fast, unattended marking with minimal footprint, the CMT Eclipse combines an engineered safety enclosure, modular conveyor interface, and flexible laser mounting options. Its tunnel architecture isolates the laser process from the production environment to control fume extraction, part orientation, and process consistency — enabling continuous, lights-out marking of tags, parts, and assemblies.

Complete marking system:

  • Selection of laser marking heads
  • Fully enclosed conveyor tunnel designed for OEM integration or retrofit into existing lines.
  • Modular conveyor interface: belt, roller, or indexed pallets; quick-change adaptors.
  • Multiple laser mount positions (top/side/angle) for optimal beam access.
  • Integrated fume extraction port and filter mount (compatible with in-plant extraction).
  • Safety interlocks and viewing windows with certified laser-safety glazing (factory-configured).
  • PLC/industrial I/O and Ethernet/IP, Profinet, Modbus TCP support for seamless line control.
  • Vision-ready: mount points and cable paths for cameras, sensors, and barcode readers.
  • Access panels for fast service and tool-free conveyor removal.
  • Optional pass-through loading/unloading gates, air-blow/pulse cleaning, and reject station.
  • Robust industrial construction — powder-coated steel frame and removable service trays.

CMT offers an industrial fume extractor for laser marking. Laser marking is a burning process, and the smoke contains particulate matter that is not healthy for the operator to breathe. The smoke and particulate also impedes the laser beam and reduces the clarity and depth of the mark. A powerful fume extractor system is recommended to assure safety of the operator and the clarity of the mark.

The CMT Fume Extractor is contained in a brushed stainless steel floor-style cabinet with casters. The 3-stage filter system is pre-piped and wired to the laser enclosure system. The complete package includes hoses and suction nozzle mounting. CMT recommends this essential component to provide longevity to the laser unit investment.

HMI - Machine functions

Automated tag production machine controls are controlled by the CMT HMI. This system can be used to take data from a customer MES system and mark indentification tags. The CMT HMI also assures the proper function of the marking source which could be laser, dot peen, or scribe.
