Speeds and feeds for 6082 T6 alloy

[JAZZCNC]

Yeah it's been a great machine around 19 months old now.

Bloody hell Dean can't believe been 19mths.!!.... Seems like 6mths. The machine does well to say was never really designed to cut aluminum.!

Listening to that video you need much more air you can hear it re-cutting chips this will cause extra heat with high potential to weld chips to tool also give a poorer finish.
Does your cam software have a function to use spiral tool path? This helps keep constant tool engagement and also quicker and easier on tools because not retracting and plunging at end of each pass.

Also because of high spindle speed/low torque you really need carbide tooling. HSS requires much lower RPM and these spindles don't have enough torque at low speeds. These spindles provide most torque at full RPM so the higher you can run the RPM the better and with HSS tools your always going to struggle.

Carbide lasts much longer and can be pushed much harder. Often people don't push them hard enough so when the get chatter etc they back off when often all they need to do is increase feed rates which changes the tool pressure. Obviously there's limit and machine strength does then start coming into play.
