Standard plywood has ±1–2mm thickness variation. Calibrated plywood is drum-sanded after manufacture to ±0.2mm tolerance — eliminating the thickness variation that causes CNC tool errors and panel misalignment.
| Property | Standard Plywood | Calibrated Plywood |
|---|---|---|
| Thickness Tolerance | ±1–2mm | ±0.2mm |
| CNC Depth Cuts | Variable results | Consistent and predictable |
| Panel Edge Alignment | May need shimming | Flush joints |
| Surface Smoothness | Good (rough face possible) | Smooth both sides |
| Laminate Adhesion | Good | Excellent (smooth base) |
| Cost | Lower | Higher (calibration process) |
| Best For | Structural, rough use | CNC, modular, precision furniture |
| Thickness | Tolerance | Surface | Grade |
|---|---|---|---|
| 6mm | ±0.2mm | Sanded both sides | BWR / BWP |
| 9mm | ±0.2mm | Sanded both sides | BWR / BWP |
| 12mm | ±0.2mm | Sanded both sides | BWR / BWP |
| 18mm | ±0.2mm | Sanded both sides | BWR / BWP |
| 25mm | ±0.2mm | Sanded both sides | BWR / BWP |
