Common CNC Machining Issues & Key Points

• Accuracy deviation issues

  Repeated clamping easily causes out-of-tolerance concentricity and flatness, as well as misalignment between internal threads and external contours.

  High-precision fixtures and single-setup processing are required.

  Real-time dimensional monitoring during machining is necessary to avoid accuracy deviations due to thermal deformation.
• Fine-adjustment thread machining issues

  The lead of internal threads in fine-adjustment nuts must be precise.

  Lead deviation often results in poor adjustment smoothness and insufficient accuracy.

  Strict control of thread machining accuracy, use of special taps, and post-machining lead inspection are required to ensure consistent adjustment feel.
• Surface precision grinding issues

  Surface waviness, scratches and internal thread burrs often occur after precision grinding.

  High-precision grinding machines must be used with controlled grinding speed and feed rate to ensure surface roughness Ra ≤ 0.8 μm.

  Finishing after tapping is required to remove thread burrs.
• Limit structure machining issues

  Dimensional deviations in limit slots will cause abnormal adjustment travel.

  Precise machining of limit slots is required to match the internal structure of the instrument.

  Travel testing after machining is necessary to avoid limit failure and ensure instrument adjustment accuracy.
