Spindle Break-in Procedure
print icon

The Spindle break-in procedure is pretty simple and straight forward and may need to be done if sitting stagnant for a period of time or if in a colder climate. 

The purpose of the break-in is to evenly distribute the lubricants and warm it up before being used. 

 

6000 rpm for 20-30 min 

9000 rpm for 20-30 min

12000 rpm for 20-30 min

18000 rpm for 20-30 min

24000 rpm for 20-30 min

 

First jog your spindle to a safe location, preferably without a bit installed before running. 

Because we understand the risks of running gcode found on the internet, here it is in raw format with each lines meaning.

 

 

;Here is a g-code in raw format, and copy this section to notepad, then save it, and change the extension to match that of your controller's format.  

M3; spindle rotate CW

S6000; speed 6k rpm

g4 p1200000; pause 20 minutes (20x 60000 milliseconds)

S9000 

g4 p1200000

S12000

g4 p1200000

S18000

g4 p1200000

S24000

g4 p1200000

M5; spindle stop

 

We recommend if you own a water-cooled spindle motor.  Run the first half of this break-in with the coolant pump turned off.  This will help heat up your motor faster.

 

The provided .gcode file and its raw text are provided as a guide.

Based on environmental conditions you may need to run it longer or shorter, and you may need to modify the values if the "G4 P" command if it is not recognized as milliseconds and is instead converted from milliseconds to whole seconds.
