Testing method
Fix the dial indicator on the machine tool so that its
probe is vertically against the end of the grinding head spindle, and rotate the spindle for testing
Fix the dial indicator on the machine tool, put a steel ball in the center hole of the spindle end, make the flat probe of the dial indicator on the surface of the steel ball, and rotate the spindle for testing.
Apply a certain axial force on the spindle
Testing method
Place the saw blade on the tester, and slowly
turn the saw blade by hand. The dial indicator is fixed on the tester fixing frame, and the dial indicator probe touches the top of the tooth (rotates in the opposite direction of cutting)bzxZ.net
