Haas’ Visual Programming System for lathes. How it works.
Our Visual Programming System (or VPS for short) for lathes gives you an easy way to write programs on the fly at your machine’s control, using the geometry and features of your part. This video gives you a quick tour of how you program using VPS. If you have a Haas lathe, or are considering getting one, this video is a must for you!
ST-55 Cutting Demo “Extended Edit”
You might remember this cutting demo we did on our ST-55 a few years back. We found an extended mix of the demo lying in the crates and we thought we’d publish it, just in case anyone was wishing they had some large turning footage to watch.
