hydraulic chuck - polishing bore and ram
The 16" hydraulic chuck on my Mazak won't make full stroke. So I've spent
eight hours removing and disassembling it. What a job! Anyway, swarf had gotten between the ram and bore on the chuck and left faint gouge track marks. These two pieces are hardened and ground to a very tight fit. Press fit taking it offG. You can easily see the tracks but it takes the edge of your fingernail to feel them. How would you take these out? The bore is 6" diameter by 3" deep. I don't want to be at this forever. Anyway to chuck it up in the lathe and power polish? Karl |
