hi guys,
I need advises on MDF cutting!
I have an home made CNC with a Kress 1050 mill and 10mm diam 2 fluttes cutter.
I was cutting MDF at 5mm depth and 1000mm/min feed.
the Kress 1050 was at 3/6 speed (ie 12000rpm I beleive).
It is cutting with so much noize and the kress charbons finally burnt after 8hrs.
I saw that the glow inside the kress was important means that the motor was pushing too much but felt it would survive...
i tried slower feed, then the MDF was burning and I also tried increase Kress rpm and same result.
are the passes too DEEP for this machine? feed too high? or RPM pb?
please help...usually no issues with other materials even aluminium but MDF seems different!
thanks in advance for your replies guys!
