In less than half the time of conventional engravers, the RX-50 engraves 3D reliefs with crisp text and vivid graphics. The heavy-duty desktop device employs a spinning worktable that works in conjunction with a powerful, 50,000-RPM spindle. Like a record player, the spindle works from the outside to the middle with 4-micron precision. It's perfect for engraving medals, awards and corporate seals.
