This procedure applies to the vibration analyzer with the RS-232 interface. This vibration analyzer uses an RS-232 connection to send the measured data to the computer.
If you have the vibration analyzer with the ethernet interface, do the Vibration Analysis - Ethernet Interface procedure.
Make sure that the drive belt has the correct tension.
For mills refer to Spindle Drive Belt - Tension Adjustment - Gates Sonic - Mill Procedure.
For lathes refer to Spindle Drive Belt - Tension Adjustment - Gates Sonic - Lathe Procedure.
Select a speed to analyze the spindle vibration:
You can view vibration measurements at any speed, it doesn't just have to be max speed.
For troubleshooting purposes, it is best to get a baseline of spindle health at max speed so the factory can compare it to the expected health of the spindle.
If you're not sure the max speed of the machine, you can check Parameter 131 for your maximum spindle speed.
Run the spindle at any given speed using the below example code:
For example, for a 12K spindle enter this program in MDI mode:
Press [CYCLE START].
How to take Vibration Displacement plots:
When taking measurements you can select the range of Cycles Per Minute (CPM) that you can see on the graph.
When viewing the Displacement Plot you want the range to include the spindle speed in which you are running the spindle, since that is where you will see the spike of vibration at.
For most Displacement measurements this will be in the range of 0-33000 CPM. However if you're testing a Compact Mill or Office Mill, you may need to switch to 30000-93000 CPM since the max speed of some of those spindles can be as high as 50,000 RPM depending on the spindle option.
Select the CPM range you need.
Run the spindle at the desired speed.
Let the vibration spike settle once the spindle reaches the speed you commanded (about 5-10 seconds).
