How to Specify Edge Banding for CNC Cabinet Parts

Identify edges using a consistent drawing view

Mark each edge on a labeled drawing, using a fixed view and reference face. “Front only” can be ambiguous for a mirrored left/right part or a rotated panel. State which edges are visible in the assembled cabinet, including the underside of wall cabinets and the ends of open shelves. Concealed joints may need a different treatment from exposed perimeter edges.

• Assign an ID to each part and match it to the cut list.
• Use edge labels such as A/B/C/D and include the orientation diagram.
• Record material, edging product and colour beside the selected edges.

Separate finished dimensions from blank dimensions

Banding adds material to the edge. For illustration, a 600 mm finished width with nominal 1 mm banding on both opposing edges implies a nominal 598 mm core width before process allowances. That is a planning example, not a universal machine setting: trimming, calibration and actual tape thickness must be accounted for by production. Tell the shop whether your cut list gives finished sizes or unbanded blanks; do not subtract edging twice.

Specify a match, not just a colour name

A description such as “white” or “oak” can refer to many décors, textures and gloss levels. Provide the panel manufacturer and décor code, the proposed edging code or sample, and the required thickness. Confirm corner appearance and edge profile for exposed shelves and doors. Tape availability and the achievable match need review before manufacturing, particularly when matching older installations.

Resolve drilling, grain and assembly together

Hardware positions may reference a finished edge, so the drawing must make that reference clear. Keep grain direction and matched sets identified before nesting. Curved edges, tight inside corners and miter-fold details may require a different treatment from straight-panel edge banding; ask for a process review instead of assuming every edge can run through the same equipment.

Check a repeatable handoff before a production run

For a repeat order, retain the approved part schedule, décor references and revision. For a new or appearance-critical assembly, discuss a sample or first-article review before committing the full quantity. Confirm whether the quoted scope is cut-and-edge only, includes drilling, or also includes finishing and assembly. Clear exclusions make supplier quotes easier to compare.
