Optimum Optimill MH50V CNC conversion

I've done some more parts on the mill and it's working great apart from the slow spindle speeds I have to run.

Here is a short video of two aluminum mounting brackets that I designed for the rear sway bar of my race car.



The mounting brackets came out really nice but I can't wait until I have a new spindle so that I can increase the speeds and feeds a bit.

I'm also considering expanding my enclosure a bit as the one I have at the moment allows a bit too many chips too escape during some operations.

 

The milling machine has been working great so I haven't done any changes to it for several months. However one thing that has been on my mind for a while is that I have no idea how hot it gets inside of the control cabinet during long milling sessions.

A quick search for temperature display brought up this unit on AliExpress for a very low price:

I bought one and it arrived a couple weeks later, here is how it looks installed in the cabinet.

 

 

 

 

It's gonna be interesting to see how hot it actually gets inside the cabinet.
