Experience sharing on the feel test for shaft hole fit during consultation
Thread Content
For the fit between the hole and the shaft, it is determined through tactile testing; for example, if it is possible to gently push the shaft (with a diameter of 200 mm) into the hole using the hand, what is then the amount of clearance?
You need to check the roughness. Ground, 1 denier.
You had better not rely on touch for this; it’s very unreliable, and it’s also an irresponsible way of putting it. In real-life communication, when such words cannot be used as evidence, respond with kindness. :)
Yes. If it’s rough, not even 5 silk can be pushed in gently.
