OKUMA LB3000 SLIDE REPAIR PART 1

Hi, everyone. I’m here with your machine’s slide, with the X-axis to my left (right of the camera) and the Y-axis in front of me. Unfortunately, this machine suffered a severe crash. From what I heard, the issue stemmed from turning the tool away from the machine’s base instead of into it, which put excessive stress on this way, causing it to crack. Let me show you—there’s a visible crack in this corner, and you can see the surface here is slightly bent or dug into, likely from the impact.

Our plan is to document everything with video and address the damage. For the Y-axis slide, we’ll contact the OEM to replace the binder, then grind and rescrape the slide to refit it properly. The X-axis took the brunt of the impact but is bolted to this surface, so we need to ensure the mating surface is perfectly flat and undamaged. I’ll disassemble it, leaving the ball screw in place, and remove the slide to inspect it. We’ll use an indicator to check for any bending or twisting from the upward impact. If the X-axis slide is undamaged, we won’t need to work on it and can simply reassemble it.

We’ll focus primarily on the Y-axis slide for now. Once we place it on the granite square, I’ll check its alignment and provide an update. If it’s within a couple of tenths and you approve, we can call it good. Alternatively, if you want it perfectly zeroed, we can do that too. My quote covered both sides, but we won’t know if the X-axis needs work until we measure it with the indicator and share the video results.

Stay tuned for more updates on this process, including how we verify alignment. If anyone else has crash-damaged slides and needs our expertise in machine tool alignment, we’re here to help. Thanks for watching, and I’ll post more videos soon!
