Y-axis vibration · Y-axis vibration i recently purchased an early 1990's Kiwa Excel 810 vertical mill. when i was checking it out i pushed hard on the table in the Y axis to check for backlash on an indicator and it started to vibrate (low humming noise). It stopped once i moved the y axis with the handwheel.
