Re: [CAD_CAM_EDM_DRO] Re: Fly cutter on Sherline.

Ahh, as always literally two minutes after I send the mail I find the answer
out elsewhere. Just after sending it the Sherline catalog appear at my door
and after about thirty seconds flicking through I discover what a fly cutter
is for and how they're used for cutting gears and teeth on the rotary table
and that they're primary use is for milling large flat surfaces (There's
even a picture for the lesser experienced. Myself). They look pretty useful
if you need to do that kind of thing for just £15, sure looks violent
though, even taking tiny slices. Same with that toothed circular saw for
cutting gears! After I saw the picture in the Sherline mag I realised they
must have been either milling a round stock to have facets. Or, I'm not
sure, but it might have been used to turn a round stock by spinning the
thing up, rotating the bar and passing it back and forth along the length of
the stock. I don't know though, does anyone think that might work? Have you
seen the steam engine in the first page of the new Sherline catalog! That's
SERIOUSLY small! The only thing I'd criticise Sherline for is not inculding
much metric along side all the imperial they use (Cockroaches? : ) When it
says stuff like, '0.003" and down to 0.002 with skill' I go looking for my
calculator. Come on Sherline, just a little metric... please? For the sake
of my calculator! Is there any difference between the rotary table and the
indexing table apart from the rotary can be laid flat on the bed? Does the
indexing table allow for CNC?

John

when I took it to be a rather cheapo company looking at what they sell. I've
order supposidly 'free' catalog with 'free' postage from a lot of massive
companies for them to NEVER arrive! And when they boast about them being
free only for them to not send you the thing it gives a very bad impression
of them as a whole. Thinking about that I have been recieving about four or
five radom faxes recently from 'The new bible', 'Win a playstation'.... etc

of the Sherline mill with the indexing table addon. But in the jaw of the
mill is a sort of cylinderical clamp with a lathe tool in it. The table is
not rotating, it's not blurred, but the bar clamped in it appears to have
been turned down by the lathe tool. Do these table rotate fast enough to do
this? On the accesories page I found something that looks very similar to
the tool in the jaw of the mill called a Fly Cutter. If I've got this mixed
up would there be anyway to clamp something into the mills jaw and then use
a tool on the bed to turn it a bar?
