Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

Looks a bit better, see my edit just above your last post for some further thoughts.

Saw it and will be testing it out tomorrow!


Also, just found a 2 flute 6mm...
Must have come with the machine xD

Might give that ago tomorrow too..


Mobile footage of the last cut.

looks pretty good in the video

I found the cutters that came with the machine fairly crap btw

Thus why I did not bother with them :p
Ordering a few off shop-apt tonight. Hopefully they will come Wednesday.
Will still try the 6mm they gave us. Worth it.

The only problem with the video was the cooling, which I expected because the compressor was low.

This is the latest result.
Forgot to mention that I am not doing a finishing pass yet.

Cut my product's case rear end.

Not perfect. Some work to do on the CAM but in terms of output it is great.



Really do need a chamfer bit...

So I started playing with the 6mm that was included. Worked well at first.
Was getting some nice test cuts with it so decided to give it ago milling out my case.



Working well for a good 45 mins. I had the feed rate at 200% as my stock settings was making quite a fine chip.
Having it at 200% made a much nicer chip that flew straight off.

It got to about 2/3s the way down the 15mm bit of aluminium and the sound frequency changed.
Went to check it out and I went to pause it but suddenly the bit started to get hot so the chips welded onto the bit.

Doh

Obviously can't go that fast when the ali has warmed up and you are doing 2mm cuts.

Was only air cooling though. I found water kept clogging up the chips and well I don't have any proper coolant system or liquid...
