Thread: ATC Options?
Just calculated the speeds for a 2mm cutter in 6061T6 and it seems I am seriously under-using carbide anyway.
In Carbide, at full speed it needs 82,000rpm, HSS wants 23,000rpm
The reason I had not seen the high speed before was because I limited HSMAdvisor to calculate feeds based on my limit of 24,000rpm, removing this limit shows the full feed & speeds.
Anyone got an 82,000rpm spindle? :)
Anyway, HSS will do the job at say 6000rpm but it will be much slower.
Should that be "Unless your'e using large tools" there Jazz?? :)

My denford triac has a 4k spindle and I don't have any problems.
I do 2mm deep cuts using an 8mm cutter at f250

I stand corrected ;)
Yes, speed is needed, it can be done on a slow machine - i've used 1/16" on the old bridgeport before but the feed rate is microscopic!
The high speed spindle is very useful.
