8x4 CNC Router: Full-Sheet Production Format Explained
The 8x4 CNC router is the same machine as the 4x8, described from the other dimension first. The 4x8 format (48x96 inches, or 1325mm metric) is the standard sheet size for North American production shops. Whether described as 4x8 or 8x4, the capability is the same: one standard sheet loads flat, all nested parts cut unattended, and finished components come off where raw material went on.
An 8x4 CNC router processes a standard 4x8-foot sheet (48x96 inches) in a single setup.
Drive System
- X/Y: rack and pinion for 8-foot travel
- Z: ball screw for depth accuracy
- Steppers for part-time use; servos for full-day production
