Counterbored Holes in Siemens NX – Illustrated Expression

Counterbored Holes in Siemens NX – Illustrated Expression

In this article, we will show you how to obtain standard-sized counterbored holes in parts of Siemens NX. You know that we use the standard holes in machine parts. And also we use counterbored holes for bolt assemblies in mechanical systems. So, Siemens NX has a special tool to obtain these standard-size holes. We start with how to drill standard counterbored holes to parts by using the Hole command in Siemens NX.

How to Drill Counterbored Hole in Siemens NX?

Click on the Hole command to create counterbored hole in Siemens NX.
Click on the Hole command.

Firstly, to drill a standard-size counterbored hole to parts in Siemens NX, you need to click on the Hole command as shown by the red arrow above.

Specify a point to define counterbored hole.
Select the hole locations to drill standard counterbored holes.

Secondly, you need to specify hole locations on the Siemens NX part by clicking on the Points dialog as shown by the red arrow above.

Define the sketch points.
Select hole locations by clicking on the part.

And then, you need to select the whole hole locations that you want to drill counterbored geometry, you need to just click on the locations as shown b the red arrows above. After you finished it, click on the Finish button as shown by the red box above in Siemens NX.

Select the counterbored form.
Select counterbored form.

After that, to drill counterbored holes on Siemens NX parts, select the Counterbored form from the Form And Dimensions tab as shown by the red box above.

Geometric Dimensions of Counterbored Hole

Define the parameters of counterbored holes in Siemens NX.
Adjust the geometric dimensions of counterbored geometry.

So, you need to specify your own counterbored hole dimensions in Siemens NX;

C-Bore Diameter: It is the top side diameter of the counterbore as shown by the red arrow.

C-Bore Depth: It is the depth of the top side of the counterbore as shown by the blue arrow.

Diameter: It is the main body of counterbore size as shown by the green arrow.

Depth: It is the sum of the depth of the whole counterbore hole as a magenta arrow.

Tip Angle: The angle of the cone o the drilled counterbore hole as shown by the turquoise arrow.

Define the diameter.
You can select Depth Limit.

Also, you can select a Depth Limit method to drill counterbored holes:

Value: Enter a depth value for the counterbored hole.

Until Selected: It drills the hole up to the selected feature.

Until Next: It drills the counterbored hole up to the Next feature.

Through Body: It drills the whole body to that counterbored geometry belongs.

Go on to defining parameters.
Select one of them.

And also, you can adjust the depth of the counterbored hole as shown in a red box above;

Cylinder Bottom: Program will adjust 40mm depth according to the cylinder bottom.

Cone Tip: Command will adjust 40mm depth according to the cone tip.

After you are done with the adjustments for your counterbored hole drilling operation in Siemens NX, click OK or Apply to complete it.

Creating counterbored holes in Siemens NX is very simple.
Counterbored holes.

As you can see above, we can obtain counterbored geometries by using the Hole command in Siemens NX.

Conclusion

So, creating counterbored holes in Siemens NX is very simple.
