I've looked and searched and inquired but not finding what I'd like to hear so here it is.
I'd like a machine that will engrave/mill aluminum to the specs required for aluminum and plastic AR lowers (yes, California) - that is, reasonably sized lettering and needing at least .003" depth. I found machines made in China and also elsewhere all in price ranges you would expect. The problem is everyone has a different take on what's needed for rigidity and power at the spindle along with what's considered milling or engraving.
So what's the general consensus about what's needed to cut text into 6061 or 7075 material. I'm thinking that multiple passes would require some accuracy in the machine but a single cut might be better with more power. There are conversions from wattage to horsepower for spindle motors but where is the 'breakpoint' between scratching the surface for engraving and cutting a bit deeper? 1/2hp, 1hp or more or .8kw, 1.5kw or 2.2kw. What are the capabilities?
Thanks for the info in advance.
