In this article we will show you how to obtain standard-sized countersunk hole in parts of Siemens NX. You know that the standard holes are generaly used in machine parts and also countersunk holes are generally used for bolt assemblies in mechanical systems. Siemens NX has a special tool to obtain these standard size holes. We start with the how to drill standard countersunk holes to parts by using Hole command in Siemens NX.

To drill standard-size countersunk hole to parts in Siemens NX, you need to click on the Hole command as shown by red arrow above.
You need to specify hole locations on Siemens NX part by clicking on Points dialog as shown by red arrow above.
You need to select the whole hole locations that you want to drill countersunk geometry, you need to just click on the locations as shown b red arrows above. After you finished it, click on Finsh button as shown by red box above in Siemens NX.
To drill countersunk holes on Siemens NX parts, select the Countersunk form from the Form And Dimensions tab as shown by green box above.
You need to specify your own countersunk hole dimensions in Siemens NX;
C-Sink Diameter: It is the diameter of the head of the countersunk geometry as shown by red arrow.
C-Sink Angle: It is the head angle as shown by green arrow above of countersunk hole geometry.
Diameter: It is the body diameter of the counter sunk geometry as shown by blue arrow.
Depth: It is the total depth of the countersunk hole as shown by yellow arrow.
Tip Angle: Countersunk hole cone’s angle as shown by orange arrow.
You can select a Depth Limit method to drill countersunk holes as shown by red box above:
Value: Enter a depth value for countersunk hole.
Until Selected: It drills the hole up to selected feature.
Until Next: It drills the countersunk hole up to Next feature.
Through Body: It drill the whole body that countersunk hole geometry belongs.
You can adjust the depth of the countersunk hole as shown in red box above;
Cylinder Bottom: 40mm depth will be adjusted according to the cylinder bottom.
Cone Tip: 40mm depth will be adjusted according to the cone tip.
After you done with the adjustments for your countersunk hole driling operation in Siemens NX, click OK or Apply to complete it.
The countersunk holes are drilled to the Siemens NX parts as above.
