Sequence of Operation:
The desired legend, composed of both steel type and logo dies, is set in the roll style type holders which are mounted in two Versa-dex carriages. These carriages are positioned on a special dove-tail mounting bar corresponding to the diameter of the piston and secured in place. The mounting bar is then attached to the ram assembly. After adjusting the marking force to the required level, the operator places the part into the fixture to accurately position and securely hold it during the marking cycle. Depressing the dual palm buttons activates the marking cycle. When activated, the ram travels vertically downward to the part. As the leading edge of the first character in each line of the legend touches the part, the marking force required begins to develop and the leading edge is indented to the desired depth. When this occurs, the ram assembly traverses across the part to indent the rest of the legend. After the part is marked, the ram raises and the assembly slides back to the start position.
