Engraving bit vs cutter bit
« on: June 17, 2019, 04:31:42 PM »
In FPE, it looks like you can increase the thickness of an engraved line by switching from a .4mm engraving bit to a 1.0mm cutter bit.

Have any of you experienced the end product when doing this?  I want to confirm that the depth is not an issue when using the cutting bit.  Also curious if swapping bits out is more expensive than extra passes using one type of bit throughout the engraving process?

Thanks!

If you look at the cost breakdown the software provides you will see a charge for each tool change plus a charge for each lump of text that is engraved. I never tried a tool bigger than 0.4mm for engraving.

Are you sure you still want to engrave? It is expensive and can give mixed results with some fonts. I now use the UV printing option. There is just one charge (about 10 Euros I think) for printing the entire panel no matter how complex. Plus you can print logos as well as text. The result seems very durable and feels a lot silk silk screen printing when you run you finger over it.

In as much as the engravings will stand the test of time, yes.

But this might be a situation where I don't know what I'm missing since I have no examples to touch and scratch at.

The plan after engraving is to use a color-changing powdercoat  (dark green / burnt orange), then backfill the engravings with a syringe, then clear coat. It turned out nicely on my VU panel I did awhile back, however the font for the engraved numbers are large...

I could not find much in the way of comparisons between UV printing and other techniques other than to say UV printing is like silk screen printing in that an ink is used but it is UV cured rather than air cured as in silk screening. However, looking on the Schaeffer site, they say they do the UV printing before they cut the holes in the metal and cut the panel out  so it clearly resists swarf and coolant.

They also say "It is also highly scratch-resistant, highly UV-resistant and highly resistant to chemicals and many solvents. " but tey would say that.

Was in an elevator yesterday and this reminded me of our conversation, Ian.
Apparently the back-filled "T" is most effected by gravity.   ;D  Or maybe some kid was stuck in the elevator and got bored.

More an argument for clear coating than screen printing, but I will find an excuse to try out the UV printing at some point.

When you get yours back, post picts and give us your impressions?  Thanks!
