My new 4 axes wood processing CNC router...

[florins]

I finally found some time to start the construction of a new 4 axes CNC router.

The characteristics are as follows:

Dimensions (active): XxYxZ 84x43x12 inches, (2100 x 1100 x 300 mm)
Rolled C7 Ballscrews on all axes: Ø25x10mm (x2) on X; Ø25x5mm on Y; Ø16x5mm on Z.
Linear supporter round rails Ø25 on X and Y, round rails Ø30 on Z, all with linear bearings.
Aluminium profile structure, 90x90 mm, heavy. Support assembly made of steel rectangular profile steel 80x80x4, on castors and support bolts.
Stepper motor driven, NEMA 34, 12Nm.
Suhner 1050W spindle with ATC.
The A axis will be a H/V 6 inches dividing table.
Computer: Atom 330 (dual core), 80GB HDD, 2GB RAM.

I bought most materials from Zapp Automation (slides, ballscrews, supports for ballscrew, stepper drives and motors - thanks Gary and Therese), KJN Aluminium (aluminium profiles and connection elements - thanks Tina), Damen CNC ("A" axis - thanks Kevin and René) and Sorotec - Germany (spindle and ATC).

Please see some images below...

Unfortunatelly, I will have to wait another month before finalizing the construction.

Any suggestions or questions are welcome!

Many thanks,
