Ballscrew machining problem ?

[JAZZCNC]

It appears like the either machining is not concentric or bearing block isn't but to be honest untill you get the end bearings fully fastened down and everything tightened correctly you won't be able to tell.
I've seen screws look much worse than this on bench turned by hand or drill and be perfectly fine when on the machine.!

I'd suggets you mount it and setup correctly attach a stepper then do some measureing.!

Nice frame end supports. Where, how much ?

Hi Silyavski,
I got it directly from SYK http://www.syk.tw/eng_index.asp (access to full price list after logging in) - very nice people and very good customer service. I was mailing with Mendy - one of the sales rep that you can also chat online with.

As to quality I'll tell you once I assembly everything. Just by looks and how all parts fit each other it seems to be very good.

Delivery time - around 10 days since payment.
On delivery, I had to pay 22% VAT when it came to Poland. It was still tiny bit cheaper then buying in Poland and of higher quality ( I got BF12 C3 grade and FK C5 grade whereas in Poland I'd get C7)


Best regards
Bart
