3-4. Cutter Installation Method 3 (Diamond Scraper)
This is for when you scribe aluminum or brass plates. The tool used is a diamond scraper, and the spindle is not rotated.
Engraving is performed by scraping the workpiece, so it achieves attractive finished results with little burring, but it does
not obtain deep cutting-in.
An optionally available solid collet for diamond scrapers is required to install a diamond scraper.
