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

Maybe its wiser and easier to drill the corners first. Then pocket with the bigger bit.

Not perfect but I think I have got it down pretty well.

I don't have a 3D probe yet so whenever I reset the machine I am obvious out somewhat.
The last operation of cutting out the case was well out for some reason..

I am working now on setting up a spoil board underneath the stock to then super glue my stock to.
This means I am not cutting out something floating in mid air.

Just another bit of aluminum stock will do that I can then glue my work stock onto with super glue?

Well superglue worked really well.
Surprised how quickly the two bits stuck together as soon as I got the air out of the gap.
Much better than cutting in the air.

Main problem atm is the water.
Thinking of building a dedicated table for the machine which is basically a drip tray that I can then have doors on each side and all the stuff bellow like the controller, spindle cooling res, cooling water etc.
Means I can flood cool too. Which will be quieter than using the air compressor.

Thoughts?

We are cutting steel on mills with mist so not to use coolant and you are going backwards. Cooling with liquid is nice for a production setup but for home? The less, the better. Mist is better for home. Do it properly as i have made it and there will be no problem. With one nozzle you can cool up to 25mm bits.

Thinking about it you are right.

Going to make a bed for the CNC that can hold the water that comes off the mist.
I actually had the bottle about a meter above the cnc the other day and just the water alone worked fine by the looks of it.
No air just gravity fed water.

Anyone tried these?

There are 2 Flute ones but only in the US from the looks of it.
I need to put a nice round edge on my product housing and these look to be the only thing available.

I have never tried that ones but seem right. You could always use 90 degree V cutter, trim the corners and slightly sand then afterwards. Just pass them with fine sand paper.

Just order it with a ball nose too.
Might as well try it, might be perfect.

Still trying to work out how I am going to reduce my water problem.
Going to be moving house in about 5-6 months so I am thinking of making a dedicated table for the rig.

One which has some decent casters on it so I can wheel it around and then some retractable feet that had then go down to make it solid.

The main thing for me is adding a box around it with window so the noise is reduced and so is the mess.
I have aluminum everywhere in my workshop atm so building it into a box where all the mess drops into a pan under the cnc is sort of what I am thinking of doing.

Means I can also use as much mist coolant as I need and it will just drip into the pan and not onto my workdesk.

Over complicating things or pretty solid idea?
Main thing for me is reducing mess externally of the machine and not having water everywhere..
