Diamond Film

[Andybrock]

Hi Guys,

Ive got ceramic stones down to 0.6um what film grit should I go in at after the ceramics? They are expensive over here so I don’t want to buy them unnecessarily!

Thanks

Unless you’re focused on mirror-polished bevels, I don’t think you really need to go further than that.   Those of us who are obsessed with the process seem to drift eventually to film-only, replacing the ceramic grits with film.  The ceramics work very well, but the film produces more uniform results – at a substantial cost.  In most instances, I will progress from 400 to 1000, then go to 6 micron and 3 micron films.  It takes a very discerning eye to see the difference between a 3 micron polish and a 0.5 micron polish.

Gents, sorry for posting in a slightly unrelated subject in this topic, but again I cannot post new topics on this forum. The “captcha” option is missing when I try to post.

Until recently the only way in removing metal from an edge above, say 1600 grit, was to use a strop with a compound (or to use whet stones).

However, the diamond films have changed all that. Not only that: they are very efficient and consistent in removing material. So, to be honest, recently I have only used diamond films up to .5 mu (and sometimes .1 mu) for this purpose. I haven’t used strops for this purpose anymore. I do use strops <= .5 mu , but I don’t go this fine very often.

My question is: am I missing out something now? For example, the “old” WE pastes has a burnishing power that helped very well in creating mirror edges. Do the new pastes have the same property? Moreover, many of the mirror edges I see published here and elsewhere (for example, Clays’s recent post) still use strops and no diamond films. Am I missing something – are strops effective in ways diamond films are not? – or is this just tradition?

And oops, the diamond films seem to have disappeared from the site. An error or are they not available anymore?

I cant help you with your technical questions simply because Ive never used diamond film but they are still available on the site.

Great question Mark!  I’d be interested to know if stropping with a paste will produce a finer edge than diamond film on a hard platen.  I don’t know if there was an “old” WE paste before it became diamond paste.  So far as I know, it’s always been diamond paste.

I checked with my browser (Chrome) and I find that there is a second pull-down menu “Lapping films” under the “Accessories” menu.

 

I also see that there is no Captcha entry required – maybe after you’ve logged on?  Or after you’ve cleared it once?

You’re right, Tom, it seems the captcha is gone (I did  get an error this morning when I didn’t enter a captcha, but now I don’t.) Hopefully it’s for good, but it stays when somebody applies for the forum – which was the original intention, to reduce the amount of spammers. Hurray! I don’t know who to thank, but I suspect Clay and Chris. Thanks guys!

I haven’t found a method yet to properly compare stropping to metal removal with diamond films. I did however do an experiment in which I completely reprofiled an edge, then used all other diamond stones and all appropriate diamond films. I.e. 100 grit stones, 200 grit, 400 grit, 800 grit, 1000 grit, 1500 grit, 6 mu diamond film, 3 mu diamond film, 1.5 mu diamond film, 1 mu diamond film, 0.5 mu and 0.1 mu diamond film, but no strops.

The result looks quite like a mirror edge:
