3-3. Cutter Installation Method 2 (No Nose Unit)
This is for when you perform engraving without using the nose unit. The tool used is a character cutter or a flat cutter.
This method does not scrape the workpiece, so it is suitable for aluminum, brass and other materials that are easily
scratched. Note, however, that in order to obtain a uniform cutting-in depth, the thickness of the workpiece must also be
uniform.
