Can you tap-test older machines?

Categories: Using MillMax

We are most often focused on tap-testing new milling tools in new machines. The circle of life for machine tools is that once their financing is paid off and they are fully depreciated they are often relegated to second operations being replaced with newer and faster technology. But, not always. With older machines, the question is:

 “Can it make this part?”

Tap-testing the program’s milling tools in the spindle of an existing older machine answers that question, at least for the milling portion. The instantly produced Dashboard tells you how fast and how deep the tools can cut in the spindle at its current condition. It is a "snap-shot" of the capability of the whole system (too, toolholder, spindle and machine). Any issues with the spindle connection, the condition of the spindle bearings or the drawbar force, all of it is take into consideration when generating teh dashboard. It also predicts surface finish and accuracy.

You may still need to verify it’s positioning accuracy with something like a ballbar test, but that old machine may still have what it takes to do the job.
