CTR Surplus – Crestline Ohio
Several years back I found some really good deals for our mirror grinding machine project at CTR Surplus. See video below for grinding machine.
They had some heavy duty servo amplifiers and servo motors from out of CAT scan machines. It was a permanent magnet motor that weighed about 100 pounds and had an indexer on it. Super good deals at the time.
