STUDER S33 GRINDER REBUILD PART 01

Hey, guys, it’s S33. I didn’t get many videos of the finish specs on this machine, and that’s my fault—my apologies. A customer came in yesterday and was pleased with everything, liking how it was dialed in perfectly. He checked it thoroughly, ensuring the spindle stayed square, using test bars in each position, transitioning from one to another, and moving components to specific places before transitioning again, all to confirm everything was square and parallel to each other. It’s all done and set to ship out tomorrow.

But I’ve got another one—this is going to be my machine. These machines are incredible, and Precision Service owns this one. We’re taking it apart completely because we want to ensure it’s perfect. Inside, there’s a lot less wear than the last one. I’ll sneak around back to show you—the back half, where it connects to these joints, wasn’t clogged. When crud, coolant, and debris build up in there, it contaminates everything, which happened with the other machine. This one doesn’t have that issue, but it is filthy. I’m not sure if it’s from us taking it apart or just accumulated grease and buildup between the two-way surfaces. It’s not ideal—you always want to change the drain and use the correct oil for any machine. It doesn’t look terrible, but it still needs scraping to ensure it’s perfectly trued up, though it won’t take much work.

Luckily, the other machine had about 19,000 thousandths of wear, with a hole toward the table axis. For this one, we’ll get it leveled. We’re going to place a straight edge on the bearing box and indicate it to check its trueness, then perform a few other checks to verify heights and alignment. I’ll get you more videos—I’m going to be more proactive with updates on this one. This is our machine, and we’re dialing it back to zero and grinding with it. Stay tuned for more videos. Thank you.
