Project Frankenmill – Part 16, Predator Vision

In my talking with Tormach, I asked about a spindle break-in procedure. They told me it should have already been done, but it wouldn’t harm anything to do it again. They suggested running it in 1000RPM increments, and measuring the spindle temperature with a non-contact IR thermometer. Once the temperature stabilized at a particular speed, bump it up to the next one.

I figured I’d one-up it a bit and get some IR imagery while I was at it, as well as get thermocouple data off of the stationary part of the spindle nose. Here is my test setup. It’s just a multimeter with a temperature probe, and a Flir i7 handheld IR camera I borrowed from the lab at work.

I collected IR images and data at each speed level and did some charting and graphing during the break-in process.

Who doesn’t love data?
