    Grease is likely to attract contamination and increase wear.

    I wouldn't want it to stop on 0.0000, then your DRO has to be zeroed off the edge of the part. I think a simple limit switch would be so much easier. Design your switch so it has minimal pretravel...

    Usually it’s the metering orifices than clog, you can take the oil lines off the manifold and see if oil comes out. Both of my boss and the v2xt had bad metering orifices. They can’t generally be...

    Might be a servo tuning issue, any overshoot would have that effect if it was less than the total mechanical backlash. How much backlash do you have? I'd look at your tuning, the drives on my...

    If it can cut inch threads then I wouldn’t worry about it, stick a DRO on it and the handwheel graduations it won’t matter. The ballscrews on my manual Bridgeport are metric and it doesn’t have...

    Are area moment of inertia for a 1.25Ē sq is .203in4, a 1.25Ē round is .120in4, a ratio of 1.69. The ratio of ys is about 1.67 so Iíd think it would be about the same force to bend the material.

    Did you check both sides of the part for flatness? There were likely some internal stress that were relieved when the shaft was split and it may have warped. If you clamped in down and faced it it...

    If you are just modifying a bushing and not messing with the ID, I would either use an expanding mandrel, or since the ID is pretty large, softjaws turned to grip the ID.

    Seems easier to do them...
