    Hardinge CHNC 4 retrofit

    Leadshine has a 200W that has a 60mm frame. That’s pretty small and could possibly fit as soon as I get an opportunity. I’m going to tear into my other machine and see just how much room is in there.

    I wonder where there was room for a motor that size in there?

    My maintenance manual has pretty good instructions, but I think you said you had one also, correct? Gary

    Also here is a side view with the plate that we are raising and lowering. It has several o-rings on it as well. Gary

    Sorry I don’t have these in PDFs, but I think it represents the check valve you have and the correct Hardinge part numbers. Gary

    I will check my parts manual for you today. My machine is a II which is 1985. Still newer but the IIIs were 90s vintage machines. Gary

    I am not sure I understand the pneumatics, but I think I understand what has to happen from the mechanical standpoint. The turret up and down has to be an air cylinder of sorts. You have to put air pressure under the plate to pop it up off the locks so it can spin. Now as far as I know there...

    Yeah without really understanding how it works I would assume that slides inside the other piece to block the air going through the hole, but I don’t see how it could seal if it’s slotted.

    I see the notch at the bottom, but it looks like the whole side is missing on yours. I assume it’s just the picture?

    So is the side missing from this piece or is it just the picture? From the parts picture it looks like it should have a flat but not be missing the side. Gary

    I have some parts breakdowns, the show the schematics and all the part numbers, but I’m out of town for work and won’t be back home until Thursday night to be able to look at it. I’m not sure if it shows all that or not but I imagine it does, unless it’s an assembly Gary

    Does the piece on the bottom of the picture just above the spring have the side broken or worn out or is that just the way the picture looks?

    Here is a PDF of the pneumatic plan. Gary

    I have a pneumatic diagram for the CHNCII, it’s bound to be pretty similar. Here is a screenshot. If it will help I can get you a pdf. Gary

    I will have to do some checking but I believe my only turret leakage is through the exhaust when the motor spins. I did happen to find this little tidbit on another post here on practical machinist. The last piece of the puzzle is the Mead H-100 shuttle valve. This is a valve that is...
