Tailstock scratching ways

[FTlatheworks]

My pm1236 tailstock put a deep scratch on the flat ways. There was no chip found and the bottom of the tailstock has a horrible finish with gouges up to .0020 deep. Tech at PM says it’s not big deal. I would like to hear what people here think.

That finish on the bottom of the tailstock shows poor quality control, all of those milling tool marks should have been scraped out, as they can hold small chips or other abrasive substances, at the very least, the scratches should be stoned out and way wipers installed to keep crud out, the best cure would be to rescrape it to remove the tool marks and then shim between the upper and lower castings (if necessary) to restore the center height to match the headstock height. When lathes are manufactured, the tailstock height was purposely left a bit high, anticipating wear.

I agree.....the bottom of that tailstock is pretty ugly. It's almost like they forgot to finish the underside of the tailstock.

How much of a stink should I raise about it. I have already complained and almost sent the machine back over the quality of other things. It functions, but I wonder, how long with some of the things I’m seeing. After talking about it with them, they make me second guess like I’m being too critical. Other machinists seem to agree, but they run much more expensive machines. Hopefully others can offer what they think. Tipton what machine do you have?

At least in this case, I do not think you are being too critical, don't know what other issues have come before.

Tipton what machine do you have?

I have a Taiwan made 1340 on the way.

How would you all handle it. I was told it was because a chip got under there and scratched it.

1340t ‘s are awesome from what I’ve seen and heard. Congrats

Nothing against PM , but that's not too pretty . Maybe others with the same lathe could chime in as to what theirs looks like . Those swirl marks look like they hit it with a rotary disk to clean it up .

It is also a couple thousandths to tall. If I put a MT in the headstock and tailstock and try the line them up with a 1/32 piece of steel like an exacto blade I can make it straight, but the tailstock is 2-3 thousandths higher than it should be. What would you ask of them for remediation?
