New Build 1000x600x200mm (newbie)

[Noplace]

Hi all, some updates, most of my free time these past months I spent on cosmetics, reassembling, cable management etc and putting the enclosure since I moved to a new room which is dedicated for this machine.

here is a photo of the machine and some acrylic cuts which were the first actual project which I made for a friend of mine.


Today I tried to face an aluminum plate ( looks funny I know, all I have at the moment hehe ) which I intend on using as a fixture for metal works. this is 6000RPM and 2 flute 1/2 cutter with 1200mm/min feed , based on sound please let me know your opinion and if you have recommended settings, I tried a fly cutter before and the results werent as smooth as this endmill. does mach3 have a wizard to generate facing operation G-code, would save me time instead of manually entering G1 commands hehe while holding the camera



All in all I'm satisfied and feel fortunate to have learned what I needed to accomplish this, but I wish if I could go back in time and design a better machine with automatic tool changing. wish I had formal education in mechanical engineering and machining so I could achieve better accuracy in the design,machining parts and assembly. but alas I guess that could be a future project.

Great machine!

What about that. Or second, if you don't feel like digging 9mm into aluminum but just 3mm



PS. With a strong cooling i mean

wow that looks aggresive, never imagined I would attempt it at this high RPM! thanks I will give it a shot with the flood coolant

last year I bought this indexable cutter http://www.rdgtools.co.uk/cgi-bin/ss...2309&NOLOGIN=1
and just tried it and its giving a much better finish, downloaded HSMAdvisor trial and for this cutter its giving me low RPM for HSS and very high for Carbide, any idea how to identify if the triangle insert is Carbide or not, all it says its Tin coated, not sure what the other abbreviations are

this is a set of them from same site, for reference http://www.rdgtools.co.uk/acatalog/1...3.html#SID=404


alternatively any recommendations to replace it with a carbide one in case those are not?

[Neale]

Those are carbide inserts. Replaceable inserts like those come in different grades of carbide and with different geometry (tip radius, for example) but they are all carbide. Never seen an HSS insert, although someone somewhere probably makes them.

[Boyan Silyavski]

They are carbide inserts right, but i think they should not be treated like a normal carbide cutter. Instead an indexable mill tool should be found in the database and edited correctly.
