    It might be worth asking Enshu, at least it would be free to try. Photos too would be nice.

    Think in triangles. The base line with the part is a 1.5" long leg with a .005" short leg, does the angle of that triangle agree with the triangle you create with whatever slop you find in your...

    I think grinding will work better than any other form of machining here. And keep in mind you are machining aluminum oxide, so use something harder to machine it, preferably diamond. How fast can...

    Does that agree with the angle you are seeing on the part? It should at least be close. As others have said, we think you have other issues than the Z-axis ways to see that much taper in 1.5". How...

    Are the other controls as well integrated to the machine as the Fanucs? Having a better control won't help much if the integration isn't as good as that of the more common control they use.

    Yes, abynormal.

    Thinking about this more, .005" in 1.5" is .04" a foot. That has to be more than the Z axis ways!

    Kitamura and Enshu.

    While your at it you should also ask 3, 4, or 5 axis. I would be currious about that.

    The motor that moves the pot is an air motor so low air would make sense.

    There is an oiler for the air to the solenoid valves that takes turbine oil, your keeping oil in that correct? If it goes...

    Mine only uses about an inch out of the reservoir for every 300 hours of spindle time.

    Pull the tools out of the pot before pressing reset. It sounds like something is interupting the tool pot...

    New aluminum specific carbide inserts, which are rarely coated, but I have never used diamond so maybe that is the best.

    Well, they do offer drivers too, god forbid. Sometimes they will even replace your drivers with theirs, it has happened to me on my video card.

    What Peter said. I forget the formula but I think you want about 3 diameters reamed then about .005" clearance for the rest of the hole. The tighter clearance helps hold the grease. Also, make...

    I just have it turn my "high accuracy" mode on when I use cutter wear comp, ie G41, and turn it off with a G40. Rough without it and just turn it on when accuracy matters, like finish passes. Real...

    80D is extremely hard for a plastic, I don't think I have ever machined any plastics that hard. Acetals and nylons are in the 65-70D range if memory serves, polyethylenes are softer. 70 to 80D is a...
