Diamond Tip Drag Engraving


jmb

Recommended Posts

I while back I picked up a conical diamond tip engraving bit in a spring-loaded carrier and today I finally had time to make an adapter so I could attach it to my engraver.  I removed the spindle motor and mounted the the adapter in place and gave it a whirl.  I also changed the gearing on my rotary axis from 3:1 to 5:1.

 

The drag engraving is extremely precise and fine and the 5:1 gearing seems to have taking the "jagginess" out of diagonal lines.  I need to contact the maker of these diamond points to see if I can change to a bit stronger spring inside the carrier to get it to cut deeper without damaging the diamond tip - somewhat expensive...

 

Here's the results.

The seller advised me that the spring is adjustable a small amount but advised against putting a stronger spring as the tip could shatter if it was "dragged" over a rough spot.  I will crank the spring all the way down on the next case but that is about the end of my experimenting.

I honestly think if it is just a smidge deeper you have nailed it, and I bet you achieve that with this current spring because it isn't that far off...at least from my unprofessional, aging eyes on a photo viewed from my iphone.
