We've seen a lot of things, and it's rare we're technically surprised. But this one had us scratching our heads!
It all started simply enough. A client reached out:
"I need a replacement for my Autostrong N212 hydraulic chuck. It broke down on my old Okuma lathe. Attached are 2 pics"
"Easy!" we thought. We picked a suitable replacement from our lathe chuck catalog - the EASYCUT THRU-HOLE POWER CHUCK 3H-12A8, 3 JAWS, 304 mm, A2-8 - quoted a fair price including installation, and soon enough, the order was confirmed.
The installation plan seemed straightforward:
Since we weren't certain whether the spindle interface was an A2-8 or A2-11, we ordered both adapter flanges, prepared for a minor field change at worst - maybe an incompatible draw tube nut.
When installation day arrived, what awaited us at the client's shop was far from ordinary. Instead of a conventional spindle face and draw tube, we faced a completely unexpected, truly unique engineering marvel - made 20-30 years ago at Okuma or by their local dealer.
So, did we pack up and leave the customer hanging?
No chance! That’s just not who we are.
After three hours of head-scratching, some innovative thinking, and hands-on teamwork, we successfully connected the old marvel with the new chuck. The lathe was back online, running smoothly, and our customer was smiling again.
The entire operation, including parts and labor, cost only CAD 3,630.55 - a perfect example of what we proudly call the best value-to-price ratio!
We thought we'd seen it all - but this old Okuma threw us a curveball we'll remember for years.
Remember: No chuck problem is too weird for us!
