If you want a true continuous path (ergo a thread), you need a servo'd rotary axis - an "indexed" axis probably can't be indexed in small enough increments to do a true/proper continuous non-stepped thread.
There is a big difference between an "INDEXER" and a "4TH AXIS" and the capabilities of either and they are easily confused due to misunderstanding of the respective device's capabilities/limitations.
Make sure you are creating/using exactly what you want/need.
My research led to the conclusion that some of the Haas rotary tables were stepper based INDEXERS that are not nor were they ever true 4TH AXIS'.
Make sure you're using the right device.... |
