Another CNC Router Design
grabcad
My first GrabCad contribution is a 4'x4' CNC Router design based on features found in other machines, real or imagined. Construction is 1530 extrusions with 1/2" aluminum plate risers, Z-Axis and stepper motor mounts. 20mm Hiwin rails and 1605 ball screws were used throughout the design which includes a 1.5Kw water-cooled Chinese spindle. Most components (NEMA 23 steppers, extrusions, bearing blocks, spindle, 20mm rails and ball screws & nuts) were downloaded from GrabCad and other 3D modeling sites. Floor stand is double 2X4 construction with two layers of 3/4" MDF on top, one layer on bottom shelf. Drawn in Fusion 360. Comments/critique welcome.
