Zymrgy is giving good advice here.
Working manually with 1mm end-mills is hard. Far better to go very shallow with each pass, than to try and cut deep, which will just result in too much heat, swarf, and snapped bits. It'll take you forever to cut it, and then think about how much harder copper is to work with, and then you'll know why most machinists I talked to winced when I mentioned cutting copper with 1mm end-mills. It can be done, but using very high RPM's, shallow passes and slow feed-rates, and it takes a long time. |

or you can just use slit saws and be done in 20 mins

Have you considered getting a WW from Dtek and modding it?
It might even work out cheaper, considering all the end mills. |

Oh, of course, I totally understand that its much more fun and rewarding when you make the whole thing yourself.
The only problem I can see is that you will have serious problems making decent microchannels, in copper, with a drill-press and an X-Y table. Its hard enough in aluminium, as you're finding out, copper is several times tougher to work with. The modded WW is something I'd definatly consider doing myself, when they finally get the Dtek block over in the UK. Until then, got my happy little circular block running very nice Good luck to you. |

iono... cutting slow can have it's disadvantages, as i found out. I'm trying to cut some fins with a 1/16" bit, first I cut about 2-3 mm deep, and cut fairly quickly, and got through 6 fins before it broke. I read this post, and tried cutting slower. I cut about .25 mm deep, at about .05mm / second accross.I got through 2 fins (cutting them another 2 mm deep each) before it got too dull.
So basically you want to cut as quickly as you can without them breaking to get the most out of the bits. I've pretty much had enough of endmills, and am going to go with dremel diamond cutoff wheels. 6 for $10, and a lot quicker. |
