Thanks! Not my design, though. It’s a German made Sorotec Compact Line 0805. I don’t think the brand is well known in the US, but has a good rep here in Germany. It came as a kit (just the mechanical part) and I had to plan the control cabinets for machine control (eding cnc 720 + JMC closed loop steppers with integrated drives) and spindle control/vfd (omron mx2) myself.

The cooling is being done by an aquarium pump and a 5L bottle of distilled water at the moment. For the winter I’ll have to make myself something with a heater, because the spindle doesn’t like temps too far below 20°C and heating up the coolant with the spindle would damage the bearings.
