hi everybody,
Despite of world wide crisis I started with my new mill I have planned and drawed during past 8 months.
5-axis.
Added sketsh (not all components are drawn).
This is composite mill - used massive Aluminium up to 80mm thick, machined artifact commercial granite panels. All gaps and emty places filled with composite-granite between thoses.
X-"walls" are 75mm thick (hight > 500mm), Y-bridge is machined from 650x210x78mm solid Aluminium, Z-axis made from 600x170x78mm solid Alu. There are no main parts thinner than 15mm Aluminium. Face U pate is 15mm thick aircraft aluminium ...
Stationar table surface is 650x630x30 pressed granite, total thickness of table 78mm. There are diamont cut holes though, there will be M8 hollow bronze plugs 80mm long ... 4/5 axles will come bit later, when main machine is ready. 4-th axis is 250mm wide, 80mm thick, 5-th axis table has 180mm diameter. For driving 5-th axis I use FA15/49 Cyclo drive (integrated in to ...), for 4-th axis I have FA35/109 - I hope to change this for smaller one ...
X,Y,Z axis uses ISEL 16/5 ballscrews with TWO zero backlash nuts for each.
X axis gas two sets of screws/touble nuts.
Z -> 2 rails 4 cars SHS20LV, Y -> 2 rails 4 cars HGW25CC, X -> 2 rails 4 cars HGH25HA. My first ATC spindle is also ready.
I already bought 5 x VCD-E (+5 servo motors) from www.granitedevices.fi .
Mach3 (15-350 Model) also ordered - hopefully next week I can touch it with my own hands.

Several parts are ready and I started with frame up. It will be very hard, but I hope ...

Im sure you wonder - why such kind of strange design ...
Yeah, but why to build separate screens and cabinets?

Regards,
Herbert

[Herbertkabi]

Gap between pressed granite and aluminium sides will be filled with composites when all parts mounted, leveled, measured, checked over and one time more leveled ...
Why I choiced this commercial pressed granite? Because Im not sure able Im to get so perfect surface.

Y-beam. L-650mm, 210mm wide and 78mm thick - hopefully rigid enough.
Sketch shows how mounted with end blocks.

Special Thanks to Dan Falck - converted my DWGs to STP,


Regards,

Herbert

[Herbertkabi]

Z-pillar (beam?) is also machined but lot of things need to be done before its ready ...
As you can see - also very massive
You can see all rails, ballscrews, cyclo drives, 5 x VCD-E (+5 servo motors) from www.granitedevices.fi ...
No more photos yet.

Cheers,
Herbert,

goes back to workshop

[idtkid]

awesome build so far, I will be looking for more updates and pics!

[Herbertkabi]

Seems impossible without problems.
Today morning I bring back to factory these pressed-granite panels. The hight of sides was near 1mm over and thickness was not exact what ordered - they forgot to over-grind the back side.
Tomorrow afternoon hopefully will be done.
Such kind stories are very tiring
cheers,
herbert

[Herbertkabi]

Problems solved, now composite panels fits correctly
When all parts ready then will go on with frame up.
Lot of threadings ... dog-tired:tired:

Herbert

Beautiful build! It looks VERY sturdy, are you planning on machining metal with it?

[jalessi]

WOW

AWESOME WORK

[Herbertkabi]

Idea was to get it sturdy, rigid, no resonances ... not like our older diy does.
and to get away from building separate cabinet/ enclosures,
Yes - sliding front door will come, not drawn on the sketch.
Whereby rorary stages of 4(5) axis mounted into side walls,
It is semi-composite-granite-aluminium built
Automatic tool change, self-washing, central lubrication ...

We milling most of all aluminium,
But will see - perhaps even some steel.

Regards,
Herbert

[Herbertkabi]

Busy with Spindles for 4-th axis. Two pieces.
Yeah, its easy to do it on the paper but in real life ...
Regards,
Herbert

[Herbertkabi]

hi again,
Spindles I spoke about will be ready next week. Just holes and threadings leftover. Looks very nice, sad to sink in to composites.
Today at last it was possible to try Y-axis, everything seems OK.
It goes not as quick as planned, every part takes up time,
Few things have been made newly, some solutions changed.
Granite rubbles, sand, quartzitic dust and 5L of WS Epoxy while away the time ... bide their time.
Few photos show that not mach have been supervened,

Cheers,
Herbert

[Herbertkabi]

hi,
There was few week of delays with sending out of CNC Mill Control. Now it is on the way. UPS tracking shows that my Mach3 X15-350 locates already in Germany, so after two-three days it need to be here. It comes in 3 boxes all together, three separate packages. Hopefully Customs procedures will not take long time and I can touch it at last with own hands and to try how it fits with Granitedevices VSD-E s. I hope it does.
Regards,
Herbert

[Herbertkabi]

Step by step it inches forward,
A little bid I proceed with Z axis,
Today Mach3 X15-350 has been received - nice,
Also 18mm thick steel plates (connect Y and Z axis) are ready,
(perhaps Im not right in my mind - what is X and what is Y on my mill ...???)
Sidewall Spindles for 4-th axis ... also ready, angular contact bearings, total 12 pieces ...
And 45mm diameter 1m long set-up shaft for precise installation,
It looks like soon I can put it all together,
Several measures need to be done and then I will open Epoxy can
Cheers,
Herbert

[Herbertkabi]

Something went wrong with attachments, trying afain,

AWESOME!!!
very expensive toys you have there Herbert

[veteq]

Hey Herbert,

You keep on showing some refreshing idea`s !!!!! I`m stunned.

Very nice mill, are you going to use such a nice spindle that you have made.
Do you allready have a 5 axis CAM program for it?
Good luck with the build and hope it will work great.

About xyz, dont know for sure (see a lot difference here on cnczone)
Look at the Jpeg for it.

Kind regards,

Roy B.

Nice build, Herbert!

It's so nice to see quality parts and craftmanship go together

Henrik

[Herbertkabi]

Yeah, guys, thank you very much for warm words.
Ouhh - I really do not know what I will use as CAM - there is LeazyCam together with Mach3, I can use Rhinos ... will see.
Now it is building time and my primitive brain will be on strike if I need to think about programs in future - installation of this controller will bring to test my brain - surely I will need help
Now I see that building is not easy at all. Myself Im modest machinist, at that there are size limits for my own shop - many parts have been ordered from professional machinists ... even so there are too much mistakes happened - where must to be M8 thread there is d-8mm hole, for example ... numbers of similar missed threads! - now I need to figure out something ... like hollows ...
Right side of face plate, there all holes are (were) 0.75mm offset ...
Very nice sidewall spindles - yes - but I cant understand why they left the last 0.075mm to grind by me - I dont want to try high-pressing and now Im busy with building a special grinding measures on my modest lathe. I use my special method - but it takes one day per one side - total four days
In conclusion - most of parts I received just like prefabricated workpieces
Smaller parts I prefer to make myself anyway,
Regards,
Herbert
