  1. Re: Doosan Turning machine ejector engineering flaws

    The Bridgeport trueing of the lower bracket helped and put this in. It was about 4 hours this morning of work, assembly, alignment, and trueing jaws to get the machine up in a total of 17 hours of...
  2. Re: Doosan Turning machine ejector engineering flaws

    The bracket the ejector bracket is attached to is bent- the one that doesn't come with the replacement ejection system. We're going to have to true that tomorrow on a bridgeport and hope to solve it...
  3. Re: Doosan Turning machine ejector engineering flaws

    I under-estimated that. We're at about 12 hours now. The ejector which was replaced 4.5 months ago, has a bent rod. We used a hydraulic press to somewhat straighten it and the bracket it is...
  4. Re: Doosan Turning machine ejector engineering flaws

    Sitting at 6 hours of down time, 2 key people working on this one, nothing appears damaged on this one yet so this is a "good one" but we're $2000 in payroll and lost time into this one...

    It's easy to get tired of knowing the pneumatic ejector is a hair away from being destroyed all the time. It's easy to get tired of knowing the Hydraulic actuator is in peril all the time, and every...
  6. Doosan Turning machine ejector engineering flaws

    These issues apply to the TT1800SY and Puma series subspindle machines.

    We run turning machines 24 hours a day, for years, so this post is not about a problem that happens every day- it's more...
