Spirit Level - Check and Adjust Tips
The calculation method of the straightness error value of the guide rail is relatively simple and convenient, and the error accuracy is accurate, which is suitable for the operation and application of the on-site staff. The moving distance mentioned in the book is not practical enough as a calculation data, and it cannot represent any calculation size. The moving distance refers to the segment of the full length when measuring the guide rail of the machine tool. The moving distance is not equal to the length of the shim. It cannot be used as the data in the calculation. The length of the shim should be used when measuring the guide rail of the machine tool. On the full-length guide rail Carry out segmental movement, use shim iron when adjusting the guide rail of the machine tool, and use shorter shim iron when adjusting the straightness error value of the guide rail, and the measured value is more accurate. The length of the shim used is different, and the measured value and shape are also different. The formula proved in the above example is used to calculate the straightness error value of the working length of the guide rail of the machine tool, which refers to the total length of the guide rail of the machine tool minus the length of the horn.
