Precision hardware shaft regulations for accessories


Because the precision of precision hardware shaft itself is 1μm therefore, it is stipulated that its fittings (shaft, bearing seat, end cap, retaining ring, etc.) have high standard accuracy and shape accuracy. Especially, the precision of the mating surface should be controlled at the same level as the bearing, which is very important and very easy to be ignored.


Precision shaft custom processing must also pay attention to the precision hardware shaft matching parts if they do not meet the above requirements, often make the precision hardware shaft after installation than the original bearing deviation of many times, or even 10 times more deviation, not at all called the five-axis precision parts processing. The reason is that the deviation of the matching parts is usually not simply added to the deviation of the bearing, but added with a different multiplier amplification.


The purpose of making two sets of orientation marks is to fully consider the compensation of the error. CNC CNC machining factory even if the rotary accuracy of both sides of the support is improved, it can also partially eliminate the coaxiality deviation between the seat hole and the journal between the two sides of the support, and the implementation of surface strengthening measures on the mating surface, such as sandblasting process, the inner hole inserted into a slightly larger diameter precision column, etc., are conducive to improving the mating accuracy.
