Common Ordering Mistake: Leaving Countersink Lines


When using the online quoting and ordering system it's easy to accidentally add features to the CAD drawing that can't be cut by waterjet or laser. Take countersinking, for example. Leaving countersinking lines in a drawing can lead to an incorrectly quoted price and even parts that get made in ways that you didn't intend.

This is a simple problem to diagnose and fix, once you know what you're looking for. Have a look at the example design shown above. The creator of the design had intended the three round holes to be cut along the smaller diameter, then a countersink created at the larger diameter shown. Here's the preview image you get when you upload this to Big Blue Saw's online ordering system:

It looks reasonably close to the intended outline, and if you weren't looking too closely, you might think that this is the intended outline for the part. But let's take a closer look at the description on the quote page:

Notice that the description mentions 4 parts in the file, not 1. When you click the part details page, you should get a better idea of what's going on.

Here you can see that the quoting system is interpreting the original 0.109 inch diameter holes as being solid parts. This means that the original countersink lines are now counted as holes in the larger part!

The solution is to delete the countersink lines before uploading the design to the quoting system.

Now the Part Details show a description of the part the way it was intended it to be.

Note that we can handle countersinking in many cases as a special order. Please contact us with your CAD file, plus the material, thickness, and number of pieces you need, and we can give you an exact price.
