MACHINING ROTORS
You must adjust for lateral run-out to eliminate wobble (run-out) from the machine before cutting. This procedure en-
sures the resulting machined rotor will have minimal run-out after cutting. The WARTHOG Rotor Matching System has
been calibrated to reduce run-out to less than 0.001” [25.4 micron] or less as measured on the rotor face.
COMPENSATE FOR Run-out
STEP 3: ADJUST FOR LATERAL Run-out (1 Minute)
This procedure will usually take between 10 to 90 seconds. Total adjustment time depends on a number of factors in-
cluding initial run-out and the resistance in the hub. Average adjustment time is less than 30 seconds, but may take up
to 120 seconds depending on vehicle set-up. When the machine is done adjusting, green lights and a displayed lateral
run-out value on the digital display will give feedback on the compensated status of the lathe.
When the machine is done adjusting, a displayed value on the DRO will give feedback on the status of the lathe. To make
the DRO easier to read at a glance, we removed leading zeros and set the output to show whole thousandths to the left of
the decimal point and tenths of a thousandth to the right of the decimal point. For example, a measurement of 0.0015”
[38 micron] will be displayed on the DRO as 1.5 [38 micron], or one and a half thousandths or thirty eight microns.
Green lights for “READY TO CUT” and “OPTIMUM” will also be illuminated as a backup to the DRO.
Detail of the computer box.
The WARTHOG Rotor Matching System compensates for run-out automatically. With the machine mounted se-
curely to the adapter and all potential interfering items clear of the rotating assemblies, press the motor on switch.
With the machine running smoothly, wait approximately 8 seconds, then press and hold the start button on the
DRO computer board for 2 seconds. The lateral movement of the lathe as measured at a 12” / 305mm diameter
(6” / 152mm from the center of hub) will be displayed on the Digital Read Out (DRO) screen. A clicking sound
will be heard throughout the adjustment process, which is the adjustment solenoid changing the angle (at the
adjustment flange face) until run-out is reduced to within vehicle specification or less.
