    Default Mazak qt200

    I've a mazak quickturn 200 here with a 640t contol.

    The machine won't start it hangs on the boot up with a replace the hard disk error. So we put in a new hard drive from mazak and no joy.

    So they said to replace the NC system, the cost of this part is really high I wanted to know if there was anyone who had this problem and if so what part fixed it.

    The machine has been broke down now for 10 weeks so I just went and bought a new machine. To cover this one until it's repaired or scrapped the machine is 2001 or so.

    Thanks for any help on this.

    Hard drives are a very common failure on those era controls.

    I doubt the entire NC unit needs to be replaced, probably a failure of the system to recognize the new hard drive...or possibly a faulty new drive.

    Mitsubishi (MEAU in Chicago) is who you want to get help from for control issues like this. You can send them the entire control, they can verify it's function, and repair what's needed.

    Now I have replaced the NC unit with a repaired one and have the machine on powering up.

    I can home the machine, turn spindle in both directions index turret and open and close the chuck.

    Now I can't cycle start the machine

    And when I jog the axis towards the chuck I get a system manfuction error 15.
