# UG/NX 8.5 Help Balancing Holes

## UG/NX 8.5 Help Balancing Holes

### RE: UG/NX 8.5 Help Balancing Holes

can't you "just" drill a hole through the solid part ?

### RE: UG/NX 8.5 Help Balancing Holes

(OP)
The hole needs to balanced so it is not always at 180 degrees?

### RE: UG/NX 8.5 Help Balancing Holes

I quote "two holes 180deg from each other".

what do you mean by "the hole needs to be balanced" ... my tires need to be balanced ?

### RE: UG/NX 8.5 Help Balancing Holes

I think KENAT meant the relevant NX forum -> forum561: Siemens: UG/NX

Is this part asymmetric to require balanced holes? Balanced within what tolerance?

Luis,
Something may be lost in translation, and it may have started with the drawing you attached, not even with what you said.
It could mean many things, and I can't tell which:
"Balance" = equal diameter
"Balance" = equivalent positions
"Balance" = mass will be inserted into holes to prevent shaft vibration.
"Balance" = opposite positions, which would be redundant after also saying "180 degrees".
Each of these interpretations could lead to creating a different model.

...or it means something else. Could you clarify what the holes are for?
The part looks cylindrical, so projecting a hole to enter the surface may require a definition of the geometry of the hole before creating the actual hole feature.

The holes are use to place on a balance machine to balance the tool to its right position. I would think it would fall more under this below:

"Balance" = opposite positions, which would be redundant after also saying "180 degrees".
Each of these interpretations could lead to creating a different model.

Hopes this makes a little more sense

### RE: UG/NX 8.5 Help Balancing Holes

so you're figuring the CG analytically and aligning the hole CL with this ... maybe using an oversize hole and a bush (eccentric?) to position the balance point accurately ?
