Tips for cutting 1050 aluminium

[JAZZCNC]

1050 is B@#~rd because it's like Cheese string to cut. What your seeing is rubbing not cutting because Chip load is too low and not enough tool engagment so creating Excess heat and melting chips gumming cutter then meltdown of material. I find 1050 is best cut with more DOC so Big chip.

Try cutting with same parameters but at full 1.5mm depth and use Conventional milling. This will produce a large chip and take the heat with it. Get plenty of Air on job to clear chips and give occasional blast with WD40 or what ever you use for lube.

Every machine is different but with 3mm Carbide cutter at 1.5mm DOC you shouldn't have any trouble provided you clear chips. Just be ready on the Over ride buttons so can adjust Feed and Spindle speed on the Fly and you'll soon find the sweet spot for your machine.

Material Must be held down well and with thin material even more important so either Stick it down with tape or Screw down in several places before doing the profile cuts. If it moves or lifts you'll get chatter and with small cutters nailed on to snap.!!
