REDUCED INSPECTIONS–Inspections are reduced dramatically–in roughing, by perhaps 90%–greatly reducing faceting time. Importantly, that makes the faceting process easier on your eyes–leaving them fresh for the final polishing.
FEELING AND BEING IN CONTROL–The Dial Indicator Attachment “talks to you” all the time–from the start of the grinding action to the end. It tells you how much material remains to be removed and how fast it’s coming off–when changing laps, it finds the new surface exactly, without trial cuts–it tells you if you mis-index–it puts you “in-control“. You know what’s happening as it happens (instead of inspecting afterwards–often too late). Its advantages are not fully describable in only technical terms–it’s as much the feeling and the knowledge of being in control that’s so important.
The design dampens out indicator flutter, and dual ball-bearings eliminate backlash.
