Use these notes to prepare drawings, application context and manufacturing requirements before requesting a CNC machining quote.
Application review
Precision CNC parts for optics, medical-related equipment, automation, electronics and communication products often have different priorities for fit, surface, material, cleaning and inspection.
Engineering communication
The same drawing can have different manufacturing priorities depending on whether the part is used for alignment, sealing, motion, mounting, heat transfer or appearance.
制造深度
