Hi
I have had a Hurco VM10i for a year and am just working on a mild steel (EN1a) job where there's a lot of roughing material to remove. I bought a 20mm Mitsubishi AJX high feed end mill and am just wondering if it's OK to use. I'm running it to the specs advised, 1mm ap, 1mm fz, 110m/min and I've run it for an hour or so without coolant and the inserts look untouched, but it machines very loudly. The spindle load is 10%, but I can see the Z axis load fluctuating a lot as though it's taking the force of the cut. Also the sheet metal on the machine is vibrating around a lot.
I'm pretty new to machining so am not too sure what sounds ok or not. I don't want to damage the machine but I also want to be cutting heavily. Does anyone have advise on how much I can push using high feed mills without damaging the machine?
I'd prefer to use an insert cutter as I have quite a few pieces to do this roughing on and so will be a lot cheaper than solid carbide. Would a shoulder mill be a possible gentler alternative?
Thanks
