That's getting close to what ready made or built solutions would cost. Is there any particular reason to go for this option?
A machine with these exact parts and specifications complete ready built by a commercial company would sell probably for around 12k€ easy (cheap labour).
The assembly work alone including the electronics cabinet is two manweeks, the parts are also 6,5k€ include profit and shipping and you are probably close to the 15k€.
Yes there are ready build machines costing 6k€ , I myself purchased a 4k€ machine ten years ago but those are in comparison a totally different category.
They are not as rigid, they don't have closed loop steppers, no vfd spindle, no professional controls, no hardend german quality iron spindles/ballbearings with precision machining and no high quality linear guides. If you test them on accuracy and repeatability you are in a different league.
In short they are skimping on every part. It might look the same for a layman but it sure is not the same

So if you want a short overview of where the costs are coming from:
Aluminium profiles: €700
Machined and anodised aluminium parts: €1000
Hiwin guiderails and blocks for X,Y,Z axis: €800
Isel axis 2x X ,Y,Z + ballscrew mounts €1000
Small mechanical parts t-nuts, bolts €100
Closed loop steppers and drivers 4 sets €750
Motor couplings holders €50
Bearings for the axis €150
Electronic parts, powersupplies etc €400
Motor cables energy chains €250
Rittal metal enclosure 60x40cm €100
CNC software and IP controller board EdingCNC €400
Iron table stand custom welded €250
T bar aluminium plate 800x600mm €420
1,5kW Spindle + VFD €300 +
----------------
6600.-
Now I could have saved €500 by machining the aluminium parts my self, but for the rest I would not know where to get lower prices for the same quality.
Some non critical parts like the stepper motors are already low cost Leadshine drivers. The 1,5kW spindle is also Chinese since a German quality one costs over €2000.- upto €4500.-
So it is actually also for some parts cheap, I will upgrade later on, for the mechanical part that has to be 100% from the start, but for instance the spindle can be upgraded later on.
