Hi Everyone, I am new here and new to CNC so please excuse me if I do not term things correctly. I am a custom knife maker that has decided to add a new line to my knives that requires a CNC mill. A good friend of mine has friend that has 2 SuperMax YCM40's one is a 95 and the other is a 96. I am looking at the 95 model it has a Centroid system on it. I went and checked out the machine today, the shop it is in they purchased them but have not used them so no one knew how to operate them. My friend (who works in a machine shop with CNC's) played around with it a bit ran an operation that was already programmed in it everything seems to be in working order, the only thing is we can not seem to find is how to release the tool holder from the spindle, any help here would be great?


He wants $2500 for this machine what do you all think?
