Shen Wai sw-830 mill

[Calkidd]

I had posted earlier on a mill and was directed to a Millrite I was also looking at unfortunately it sold.

I came across this Shen Wai sw-830. I did a search and couldn't find any info on it. I found posts on lathes which appears they make a good lathe. I was hoping their mills are well built too. Any opinions or suggestions would be helpful.

I don't have a lot of space and all of my larger tools are on wheels. This appears to be an ideal mill.

The sellers description says it is very similar to a Grizzly GS0731 and is asking $2k from his previous $2200.

Looks pretty serviceable- and has a simple dro which is handy since I think the leadscrews on those are 8 tpi not 10

I plan on taking dial indicator. What do I need to check? I assume the quill to see if the bearings are good. How do I measure the run out on the table's X/Y axis?

I wouldn't waste time trying to measure the table since you can readjust the gibs later. Don't be overly concerned about backlash in the handwheels either, most machines will have some. With the dro, it isn't a big issue.
I would spend my time checking that the quill is a nice snug fit in the head; this is something that cannot easily be corrected if machined poorly from the factory. Check that the downfeed works also.
Check the spindle internal taper, make sure it is not scored or otherwise damaged.
Check that the spindle runs smoothly and quietly but don't be too critical since you can replace those bearings also, later.

In summary, spend the time looking over the headstock, it's the heart of the machine
Leave the dial indicator at home and use your eyes

Thanks for taking the time to go over this with me. Given the fact this guy put 3 DRO's and seeing how clean it looks I can only assume he took care of it.
