Polishing of Steel Alloys
 50 - 80% Speed
 30 - 50% Power
 70 - 100% Frequency

0 Focus
 600 DPI
Some steel alloys are easier to polish than others. For best results, clean off the
surface with alcohol prior to processing. Any leftover grease, oils or residue can
affect how well the polished mark turns out. Polishing the metal where the final
marks result in a bright white engraving requires finer tuning of settings, more so than
the etched or annealed marks. Determine a base speed and frequency setting and
adjust the power in small increments/decrements. If you are unable to get a white
bright mark, increase the frequency setting and try again by adjusting only the power.
Annealing of Steel Alloys
 6 - 12% Speed
 100% Power
 1% Frequency

600 or 1200 DPI
 Focus – see comments in next paragraph
To achieve an annealed mark, the focal point should be significantly away from zero.
The unfocused, broader beam provides the heat to change the surface color without
actually penetrating the metal. The focal point can be either closer to or away from
zero. Focusing away from the material should be in the range of -.060” to- .090”.
Focusing closer to the material is generally in the range of +.070” to +.110”.
Both focusing methods will result in a dark black annealing of the metal. Focusing up
typically results in a slight indentation of the metal.
Multiple passes can darken the mark even more (no data to confirm whether multiple
passes offer more permanency).
