Bridgeport Torq-Cut TC4G Retrofit

It looks lovely until you undress it, then horrors emerge.

But they look like good quality parts, at least. That probbaly means they will clean up.

Nice.
The fun has began !

Agree with both of you.

I ordered the replacement thrust bearing already. Part number below for anybody needing it.

Thrust bearing = INA ZKLF 2575 2RS

While I was cleaning the mill I have been contemplating what computer I should use to run this thing. I keep coming back to using my RPI4 communicating with a 7i92.

Here are my latency results over a 10 minute duration with 8 glxgears and moving files around. The 3 different views are from different arm frequencies. (800mhz, 900mhz, and 1500mhz)

Notice that the best numbers come from the 800mhz frequency.

What do y'all think about the results and why does the latency change with arm frequency? Any reason I should not run the mill from a RPI4?

Took more covers off and found more stuff to clean. Also seems like there is a Y axis thrust bearing going out.

A thought on the trust bearings... There are no oil lines going to them and I am sure that the previous owner did not PM this thing. I think I am going to run oil lines to the thrust bearings and meter the volume to an acceptable mount specified by the bearing OEM. This should help extend the life of them.

That still looks pretty clean compared to a Hurco i retrofitted a while ago, it was full even under the covers!
