Background

In the existing shafting alignment quality detection method, a ruler measurement method, a thickness gauge measurement method and a dial indicator measurement method are commonly used. Under the current detection standard, the specified allowable deviation value of the shafting flange is 0.1mm of deviation and 0.15mm/m of deviation.
