    Default Hardinge CHNC turret valve permanent blowing

    Hallo
    I have just started my CHNC with an Allen Bradley Control
    It seems that everything is working fine just the Clippard Valve for the turret blows permanently thru a hole in the aluminum body. Is that normal?

    My compressor works hard to get enough air.

    If I turn the turret with the swith at the reader unit it turns perfect.
    I have unmounted the valve and there is no rubber seal between the aluminum body and the valve. Maybe the seal would close that bypass?

    Thanks for the help.

    If you are referring to the Air Cushion / Bump Stop. That always leaks air. The CHNC is an air hog. And if you are running one with just a slight compressor system. The compressor will work hard to keep up. It is one of the negatives of this machine.

    Post a photo of what you are talking about and perhaps I can help you more.

    I remember way back when......
    We ran two 1995 CHNC3's with one 5HP 60 Gallon Compressor. You could go into the compressor room and grill steaks on the compressor's cylinder heads.
    With just a touch of motor oil Ajou sauce.

    Thank you so much JT

    I am not able to post aphoto
    but it is like you mentioned. It is the Clippard valve for the turret steering.
    If the turret sits down after rotation it is blowing permanantly thru that bypass hole.

    I think I have to buy a new compressor.....
