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

FUCKKKK
Just snapped the probe.

Anyone know if there are other probe ends that fit this one?

Must be going to wrong suppliers because nearly any decent stockist will be cheaper than AW.
Give ASC metals a ring and ask if they deliver out your way.

Well, I just ordered 5 bits off this local company for some soft jaws.
Worked out cheaper at 5 quantity than AW.

Sent ASC an email too. Thanks for the sugetion.

Quotes so far for 15mm 5083 plate...

Company	150x105	112x108	Postage
AW	£5.43	£4.17	£12.95
Local Ali stock	£10.75	£9.25	Collection
ASC	£5.50	£3.50	£10
Brindley Metals	£6.80	£6.10	£20

6082 is better to machine.

Why don't you get 6" x 3/4" flat bar billeted and machine all over. It will work out cheaper.

idk

Always used "eco cast" from AW. Apparently, it is 5083 but ground?

Need to look into types of alloys. Hoping there is a decent YouTube video on it. Will check later.
Just finished a part with the new vice and it is looking amazing!
So much better than the drill press vice xD

I'd post photos but my phone died...

Here is the area of the part I was having problems with.
The chamfer would be uneven. Now it is perfect.

This is my contraption.

I know a few will laugh but it works really well....

Would prefer to machine the top in the vice and then flip in the vice.
I hate the super glue and the removal of it (which even on fresh plastic is scuffing up the surface finish)
Will try it once I have some soft jaws.


Also, I got yelled at for running this tiny cut without lubricant..

Making some nice chips...

6mm, 25mm Flute. There is a bit of chatter when it goes Z- 10mm. But is holding up fine.
I used a 6mm carbide drill to pre drill the holes. Worked out really well. Only a hair width of gap between the endmill and the stock but never heard it cut anything when dropping into the hole.
The 6mm drill bit is pushing the machine a tad. Can see it flex at 0.2mm Feed per Revolution. Dropped it to 50% in Mach3 and it still flexed but very little.

New Styli just arrived. Trying out the Renishaw ones as they are distributed and possibly manufactured in the UK?
The cheapest M3 with 3mm ball is 21.2mm long (ball end being closer to 2.9mm diameter than 3mm, this typical?).

The shorter length actually works well for me as with the new vice installed, I don't have much Z height anymore.

£49 for 2 probes, shipped next day (I ordered past 5pm so same say shipped) and was sent first so arrived today.
Bit better than the 100 Euro the dude who makes these probes quoted me for a single Styli...

Shipped same day if ordered before 2:30 pm and they are made in the UK.
I have an image just above of the Styli but image host is playing up.
