Air Powered Roll Marking

Columbia Marking Tools' classic roll marking machine features a custom-designed and built ram cylinder that delivers the driving force for marking pressure. This innovative system employs a "Seek & Find" pressurization method to ensure consistent pressure throughout the marking operation. The all-air marking system is ideal for high-volume marking applications and is versatile enough to handle both round and flat parts efficiently.

Roll marking delivers a deep mark than any other method in a fraction of the cycle time. The high throughput of the roll marking system provides a reliable and economic solution for industrial part marking.

Technical Data Sheet

Station Components

The 260/860 Roll Marking Machine is composed of the following key components:

Air-Powered Keyed Ram: Provides the driving force for marking operations.
Slide Cylinder: Provides the secondary driving force for marking operations.
Controls: Includes operator interfaces for starting and managing the marking cycle.
Stamp Holder and Stamps: Designed to securely hold and position the marking stamps. Upgrades include numbering heads for serial numbering.
Fixtures and Roll Cradles: Design to hold or roll part during marking process.
Frame Options: Mounted on either a bench frame (B) or a floor-style base (F), depending on application requirements.
Safety: OSHA required palm buttons or guarding with a part present cycle start.

Additionally, numbering heads can be mounted on the roll marking machine for specialized numbering applications. A system of air valve devices precisely controls the impact to ensure consistent and accurate marking results.

Marking Tooling

Roll marking requires two distinct sets of tooling depending on whether the part being marked is flat or round. Each type of part requires specific dies, holders, and fixturing to ensure precise and consistent marking.

Marking Round Parts

When marking cylindrical or round parts, a flat die or flat holder is used. To ensure a clean and even impression, the part must rotate as it is marked. This is achieved using a roll cradle, which allows the part to roll smoothly under pressure while the die presses the mark into the surface. The rolling motion helps prevent distortion and ensures uniform depth and clarity in the marking.

Marking Flat Parts

Flat parts require a different setup. Instead of a flat die, a round die or roll-type holder is necessary. The round die rotates as it applies pressure to the stationary flat part, imprinting the desired mark. To keep the part stable during the marking process, a part fixture is used to secure it in place, ensuring accuracy and preventing movement that could result in misalignment or inconsistent depth.
