I recently received a Vertex rotary table and was curious as to what
the consensus is on these numbers gotten off of the enclosed
certificate. Would these be considered average quality numbers?:

1) Flatness of clamping surface(Concave): 0.0008"
2) Parallelism of clamping surface to base: 0.0008"
3) Squareness of clamping surface to angle face: 0.0008"
4) True running of clamping surface: 0.0006"
5) True running of center hole
(1) Measured at hole edge: 0.0008"
(2) Measured at arbor 4-in. long: 0.0012"
6) Indexing accuracy of direct indexing mechanism:
Maximum cumulative spacing error: .50"

Thanks.

Sounds average for a decent rotary table when new. Now the big question
is..are you going to be using this 8 hours a day, 7 days a week? If
not..dont worry about the materials holding up over years.

If you are..then perhaps a better US made rotary table may be better.

Ive got one identical to yours btw..and it works just fine, and has held
up for the past 3 owners just fine G

One could not be a successful Leftwinger without realizing that,
in contrast to the popular conception supported by newspapers
and mothers of Leftwingers, a goodly number of Leftwingers are
not only narrow-minded and dull, but also just stupid.
