Mechanical Accuracy Testing
· A micrometer is used to detect the end face and conical hole runout at the tool interface, and the test data are registered.
· BT/HSK/ISO/SK and other special checking rods are selected to detect the distal runout of the spindle. The runout of the checking rod at 200 mm is detected and the runout data of the checking rod is registered.
· If the spindle runs beyond the standard after replacing the bearing and repairing the taper hole accuracy, it is necessary to test the coaxiality of the spindle core with professional equipment, so as to determine the main reasons affecting the spindle runs beyond the standard.
· Professional puller is selected to test whether the pulling force of spindle broach mechanism is normal or not to judge whether the disc spring is insufficient.
· Check whether the spindle sleeve and bearing seat are worn, check whether the cooling water channel of the spindle is unobstructed, check whether the air channel of the spindle is unobstructed, register the test data, especially note
