Requesting Guidance on Designing a CNC Machine for Machining Wood and Polystyrene

[POORIAPK]

Hello dear friends and engineers. For about two months, I have been working on designing a CNC machine that can machine wood and polystyrene without any issues in dimensions of 2500x1300x500mm. Additionally, this machine has a fourth axis and a rotary, which are separately placed on the machine's table.

Due to my lack of sufficient experience in CNC design, I request you to take a look at my machine and point out any flaws so that I can fix them.

Furthermore, some parts of the machine have been removed to clearly display its structure.
Also, this is a preliminary design!


Materiels : 1 - 80x80mm Aluminium Extrusion T-Slot Profile (8 slot), slot width 10mm
2 - Closed Loop Stepper Motor NEMA 34 - (85Kg XY , 120Kg Z)
3 - Linear Guideway Rail (HG20 XZ , HG25 Y)
4 - Ball Screw Diameter 20mm Pitch 5mm
5 - 2.2kw Spindle motor water cooled
