** Would you like one of these machines? **
We are now creating 2 lists. One for people interested in the production machine. No money is required, just send your contact info and we will get back to you in order when machines become available to purchase. You then can decide if you want to put a deposit, or pass to the next person on
The second list is to get 2 local Toronto area buyers who will get a small discount in exchange for buying the first 2 machines. You'll need to pay up front, and the machine may take 2-4 months to complete. there may also be quirks after delivery that will be addressed on site. (that's why we need local). We will come to you location to set them up, help with your initial applications, and provide extended support to come and fix anything or update anything that needs it. In exchange for this leap of faith, you will receive a modest discount, and a lot of extra help. WARNING, this is not a cheap machine, so this is really not for anyone that is looking for instantly sliding a machine into production but also not likely for a hobbyist that doesn't have a master plan and parts ready to cut.
Contact vfx@failkeys.com if you want to be on either of these lists. Thanks!!!

Material:
Starret O-1 flat stock, annealed condition.
Cutters:
Kyocera 4mm 3 flute titan AX end mill for roughing
0.27mm width of cut. 7mm depth of cut. 30000rpm. 4600mm/m.
Kyocera 3mm 2 flute TiAlN ball nose for finishing
0.1mm depth of cut. 0.076mm step over. 36000rpm. 10000mm/m.
Feeds settings were done with the help of Sandvik's online tool recommendations, and then toned down because we are of course not using their tools. Spindle load was about 350W for the heaviest rouging so the machine has a lot more to give, although it needs a wider vise.
Adjustments for future: minor chatter in helical moves outside the vise clamping area. Wider vise should be used. Finish pass should definitely be run with coolant. Machine is currently restricted to 10000mm/m. Full speed of 30000mm/m will unlock a lot more efficiency. Likewise the spindle running at 50000rpm instead of 36000rpm will allow better surfacing.
Temporary JMC integrated servos leave a surprisingly good finish on this steel when a logical cutting strategy is used. New higher performance servos will only improve it.
