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?
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.
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.
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.
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
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.
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.
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.
As you can see above, we can obtain counterbored geometries by using the Hole command in Siemens NX.
So, creating counterbored holes in Siemens NX is very simple.
