I. Quick Initial Inspection of Finished Product Appearance: After cutting standard-sized samples, observe the finished product's condition: burrs, tilting, wrinkles, or stretching deformation of the aluminum foil at the cut indicate precision deviations, requiring further inspection.
II. Targeted Inspection by Problem Area:
Cutting Surface Precision: If the cutting surface precision is poor, check the saw blade wear and spindle runout precision to confirm whether the saw blade is damaged or the spindle is out of tolerance.
Length Dimension Precision: If the length tolerance exceeds the standard, check the feeding parts (servo motor, lead screw guide) to confirm whether the components are worn or misaligned.
III. Quantitative Tool Inspection: Measure the finished product dimensions with a micrometer and vernier caliper. If the deviation exceeds production requirements (normal ≤ ±0.1mm, high precision ≤ ±0.02mm), the precision is considered abnormal. Use a dial indicator to check the spindle runout; exceeding 0.01mm requires repair and calibration.
IV. Daily and Timely Inspection Plan: Establish a first-piece inspection + process inspection system: sample and inspect the dimensions of the first piece of each batch, and conduct hourly spot checks on the width and end face flatness during the production process to promptly detect any accuracy abnormalities.
