I bought a sharp 2414 mini mill about 2 years ago, great machine you will like it . But who ever assenbles these machines do not do a very good job. Heres are some of the adjustments i had to do to my machine to get it running good When you get the machine make sure the service tec checks these items its his job.
Check and adjust backlash
Check and and adjust gibs ,Icould press on the side of the spindle and it would move .006
There is a ring nut that holds the tool carosel on it has a locking washer above the ring nut (the kind you bend a tab down to lock the ring nut) mine was not bent down
allowing the ring nut to tighten and locking the tool carosel
And the most important , take the way covers off and check the oil lines make sure there all tight. A sharp owner on another form had one of his oil lines come lose thus the machine was not getting any oil for over a year .The machine was totaled but sharp admited it was there
mistake the line was not tightend and gave the guy a new machine after the warenty had expired.Here is a link to the article.
