Yo ,

I needed a mill ... liked the PCNC 1100 from tormach , but is expensive ...
so I decided to build my own , from scratch ... Design is very common
( so far I have seen several machines here almost identical ... ) .

My english is not so good , so I will let pics talk for me ...

All aluminum components were machined on my cnc router ( my last
project , finished 3 months ago ) . First picture is taken in my shop ,
reprezenting my cnc router .

Here it is ...





























I stiil have a lot of work ahead , but I think I will finish this year .

Components :

THK SHS30CA rails , 80_80 aluminum extrusions , 1" thick MIC-6 aluminum
plates , ISEL 2505 ballscrews on Y and Z , LeadScrewInternational precision
ground 3210 ballscrew on X , Colombo RV110.22 / 10hp + Delta drive ,

As for motors , I will use those weird hybrids from keling ... closed loop
stepper motor kits ( 8N/m stepper motor , 1000ppr encoder , digital hybrid
servo drive ) .

I'll be back !!!

again WOW!

damn that's gorgeous!

damn that's gorgeous!

Thank you .

I assume that you are reffering to the vertical mill ... it's a work in
progress , it will look much better at the end .

If you are talking about the router , that's nothing ... I have an idea
that's much better then this . AC servo , BT30 spindle with ATC , work
table made from a single piece of aluminum ( 2" thick MIC-6 plate ) ,
vacuum clamping sistem , 8 by 4 working area , Newall DRO ( just for
fun ) , an so on ...

complete cnc nublet here so forgive my ignorant questions...

you are making a gorgeous cnc mill mostly out of aluminum, right?
how rigid and strong is this... or how does this compare to a equivalent sized machine made of cast metals and steel in terms of performance?

thanks in advance,

Al

Holy smokes, your workshop is far too clean. I'm so jealous!

I have no idea ... but I also have no posibility to work with cast metal or
steel . so , I used the next best thing. But I really hope that the machine
will perform well . It's already heavy ( 250KG / around 500pounds ) , the
design is fairly good , and it's stiff ... entire assy is only at mokup level
now ( very few screws , about 10% of final amount needed ) , nothing
is aligned yet , and still , the entire **** does not vibrate when I strike
the column with a rubber hammer ...

Here are some pics of final project , made in Rhino ... You will see that
the base structure is pretty solid ...

It was clean ... now is a mess . Here are some pics taken when
the shop was a little cleaner ...

colour me green!

Amazing clean workshop do you have cleaners come in? :-)

Beautiful work. Thnks for sharing, and I am looking forward to seeing the further build pictures.

Can't wait to see a video of that mill working.

Nice design and work- What's the spindle ? How much do you think your build cost will be for materials?

Thanks ...
Spindle is a Colombo RV110 CPE32 ( 10hp , 7,5Kw , 18000rpm )
Cost ? Probably in the vecinity of 5000USD ...

Looks like a great finish on your profile cuts what do you use to cut the profile with ?

Profiling toolpath is generated with Artcam , based on vector ( DXF file ) .
I use a carbide cutter ( 10mm dia , 3 flutes , 45 degree helix ) at 8000rpm .
And a lot of WD-40 ... the machine is set-up true and square , maximum
error around 0.02mm .

Cutting speed is around 800mm/min , depth of cut 2mm . The blank is cut
on a bandsaw ( Craftsman Pofesional , imported too from USA ) , slightly
bigger than the finished part ( about 2-3mm ) . So the cutter does not
have much job to do ...

Update :

It's starting to look like a mill ... The head , the compensation struts ,
motors on X and Y . Verified the weight compensation ( with the motor
mounted , I can actualy move the Z axis with 2 fingers ... very easy ) .
Without the motor , it wants to go up ...

Now I have to wait for the third motor ( on Z axis ) , still on transit from
keling , and the power supply ( can't wait to test movements ) .

Update :

The ballnut block on base axis . Milling motor is now in place , also
found a box for electronics ...

Katran,

Beautiful work and a beautiful workshop.

What extrusions are you using for the z-axis. It looks like you are using 4 extrusions of the smooth variety, but unsure of the size.

What are you using to hold the extrusions together....besides the front Mic6, the side and the top plate?

Thanks for the great pictures.
