We result ( why we are driving to Frankfurt) will be the same for both of us. BUT ! We both will reach our destination and our goal, never mind that I will spent 3 times more, will more tired and etc. You drive 300 km/h, I 100 km/h, You drive with more comfort then I and are more fresh at the end of journey and etc. In another word, just imagine that You have Porsche Panamera and I have Fiat Cinquecento and we both drive our cars from Munich to Frankfurt (why Germany? because there are no speed limits on highway there) to attend football match of world cup final.
I clearly understand, that the C beam machine in comparison with some professional big milling machines is like a waving flag in terms of stability.īut I thought by mistake, that the right understanding of the limitation of cnc router and make appropriate steps of overcoming this limitations could be a key for quality cutting. But please, can anyone tell me: just set this parameters on Your C-beam, use (or do not use) cutting fluid or or something else, buy this particular end mill, use that type of aluminium (extruded, 6061, 6063) and so on and so on and You will get the cut You are speaking about: shine as mirror, clean, smooth, without tool scratches, which will not need sand paper, file or any other post production steps Yes, I know, that there are many online and offline calculators to choose the appropriate cutting parameters. Thank You so much for any advise and help in advance. Please help with some suggestion and answer my questions, because I am very disappointed with that. If I set that feed rate and spindel speed, can I run my Cbeam machine, or it will just collapse, because this guys use 2.2 kW spindel, and my Bosch is just 0.85 kW max.Ģ.) I can even upgrade to their 2.2 kW spindle, to have all the parameters of their machine the same.īUT, is C- beam rigid enough for 2.2 kW spindel. They point out the end mill model, they write about cutting parameters (feed rate, spindel speed and so on).ġ.) I can buy this end mill from ONSRUD. The guys cut the aluminium plate like butter.
My machine is C beam, spindel is Bosch PR20EVSK Colt Palm. The cuts, coming from big milling machines, looks like mirror, they do not need any sander or file or something like that. What I mean for acceptable? well, some typical metal shining, absolutely smooth and even, like polished cut, which I saw many times on big milling machines. I was already trying different aluminium (6061, extruded) different end mills ( some expensive 1 flute upcut end mills from Amana Tools, some cheap 2 flute end mills from ebay.).
