CMT Model 78 - Mite-E-Mark air impact marker

The Mite-E-Mark packs a punch for its small size. The compact Model 78 can fit into tight spaces and provide production marking of station ID and QC marks in fully automated production. This reliable system ensures consistent marking performance, enhancing productivity in manufacturing environments.

Is an Air Impact Marker the Same as an Air Cylinder?

No. Despite both using compressed air, they operate on different principles:

  • Air Cylinder: Generates linear motion through air pressure and piston area, calculated by the equation F = P × A. For example, the Model 88 cylinder produces 80 lbs of force at 80 psi.
  • Air Impact MarkerOperates on the principle of F = MA (Force = Mass × Acceleration). The acceleration of the rod/stamp holder generates high force output, resulting in 6,000 lbs of impact force with the same 80 psi.

Force Comparison- Model 288

  • Bore Size: 1.25"
  • Air cylinder Force: 80 lbs
  • Air Impact Force: 1,500 lbs (1" stroke) 2,500 lbs (2" stroke)

Product Information

The COMPACT Columbia Model 78 is an impact marking cylinder designed for robust and reliable performance. Here are the key features:

  1. Design: The model is built as a rugged pneumatic tool with various pockets at the rod end for stamp character inserts, allowing it to deliver powerful impact blows.
  2. Impact Force: Capable of delivering a substantial impact force of up to 2,500 lbs at 80 psi (pounds per square inch). This makes it suitable for various industrial marking applications.
  3. Solid Body: Solid one piece body machined from quality tool steel.
  4. Dependability: The Model 78 is highlighted as a dependable marker, offering reliable performance while maintaining a low investment cost.
  5. Rod Action: The rod features air forward and air return double acting motion for maximum reliability in automated applications.
  6. Keyed Non-Rotating Rod: The Mite-E-Mark can be upgraded with a keyed and non-rotating rod, ensuring precision and accuracy in the marking process.It is also available without the keyway in a more compact and smaller foot print to fit into tight locations.
  7. Stroke Length: The model offers 1" and 2" inches of stroke, providing versatility for different marking requirements.
  8. Compressed Air Requirement: The compressed air provides the propusion to move the ram/rod forward and this mass in motion provides the over 1 ton of impact force.

“GA” and “GB” Rods for systems with excessive vibrations. The standard “OA” and “OB” rods use a set screw to retain the stamps. For most applications this works very well. However, machines with excessive vibrations can cause the stamps to randomly fall out. CMT has a solution. The “GA” and “GB” rod use a pin and oring to assure solid retention for shaking machines.
