Aerospace Application: Universal Marking Table

Custom Universal Marking Table
Marking Requirement
A customer in the aerospace industry needed to mark a variety of large parts measuring up to 48" in diameter and weighing up to 600 pounds. They wanted a single fixture that could mark all of the parts for a single production cell. The requirements of this application included serialization of all parts and marking human-readable text and/or Data Matrix codes.

Solution Provided
Dapra Marking provided a modified HD2 Portadot marking system, attached to a custom table with three axes of motion: vertical (36"), radial (36"), and angular (180°). All three axes are manually adjusted and locked in place. The radial arm is supported by a counterbalance that holds the arm in place when the locking handle is loosened. Each axis of motion has a scale in the appropriate units to facilitate consistent placement of the marking head. The table also includes two general-purpose locking drawers, one drawer for the marking controller, a keyboard and mouse tray, an adjustable monitor arm, and space for a PC.

To use the system, the operator places the part against the two 90° locating blocks. Next, the clamp is placed in the appropriate holes to allow the v-block to engage the part. The marking head is then moved into position so that the marking window of the head is over the area that needs to be marked. The trial run feature of the marking system is used to fine-tune the final placement of the text, logos, and/or Data Matrix codes.
