Re: [Emc-users] Encoder Discs

[Roland J. <rol...@gm...>]

I looked at similar some months back.

These guys wanted £1000 to get started. Still not sure how many discs I
would get for that.

And an american crowd;

quoted;
10                                                       $66.65/ea
100                                                        $6.65/ea
500                                                        $4.65/ea
1000                                                      $2.80/ea


And a time tooling charge of $665.00

So, all in all, unless you're pretty serious about it, it'll cost a bit.

But I'd be curious to see what pricing you get. I tried hard to source
'stock' discs, but they would have none of it.

Roland
