We are looking at a lightly used ST-28Y. We have an old SL-10 that has served us well and a Haas horizontal mill, including other cnc lathes and mills. It seems I heard there were some bugs in the NGC . What do you think of the newer Haas machines, and are there issues that need to be watched for? I would like to hear from you if you have direct experience. We will be doing no heavy machining of difficult materials or super tight tolerance. Mostly in the +- .004 range. In addition, how do their robot loaders stack up to others?
