    What tolerances can CNC turning hold? Tolerances are confirmed against the drawing during DFM review rather than quoted as blanket values. Feature-specific callouts for OD/ID, concentricity, runout, threads and surface finish are reviewed against the material, stock form and quantity before quoting....
  5. Metal Stamping Tolerances: Reading A Drawing Before Quoting
    Which tolerances can a stamping tool hold? In metal stamping, tolerances are process-dependent. Pierced and blanked features in thin material can typically hold tighter tolerances than formed features, because forming adds springback, thinning and radius variation. Hole-to-hole position depends on p...

Pierced and blanked features in thin material can typically hold tighter tolerances than formed features, because forming adds springback, thinning and radius variation.

What an engineer still needs from you

  • material and material condition (grade, temper)
  • material thickness, plus the key diameter, height and wall thickness
  • tolerances, burr direction and the visual acceptance standard
  • annual volume - it decides whether tooling is single-hit, progressive or transfer
  • surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
