供应The difference between full-length straightness and meter straightness in Chuxiong
Key words: full-length straightness, meter straightness, online straightness measurement, straightness detection equipment, straightness equipment

1. Total Length Straightness

The maximum variation of the measured object from the ideal straight line over the entire length range, reflecting the overall straightneondition. For example, for a 10-meter-long guide rail, the full-length straightness refers to the maximum deviation value of the overall bending within 10 meters.
Application scenarios: It is applicable to situations with strict requirements for overall straightness, such as machine tool guide rails and large steel structures.

2. Straightness of 2-meter-long line (local straightness)

It refers to the maximum deviation from the ideal straight line within every 1-meter length, focusing on local details. For instance, the straightness per meter of a 10-meter guide rail needs to be measured in segments, and the deviation of each 1-meter section must meet the requirements.
Application scenarios: It is often used in scenarios where precision control is needed in segments, such as precision steel pipes and long shaft parts, to ensure that local quality does not affect overall performance.

III. The choice of which evaluation method to use depends on actual needs:

If the overall shape is emphasized (such as in bridge steel structures), the straightness of the full length should be prioritized for assessment; if the local performance is of concern (such as in precision shafts), the straightness should be controlled in segments by the meter. Both methods are often used in combination to ensure comprehensive quality control.
