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 (ST-50’s bigger brother) 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.

The BMT65 Turret and Live Tooling for Haas Lathes

Why move your turned parts to a mill for secondary operations when you can machine them complete on a Haas lathe with the BMT65 Turret and Live Tooling? 

The BMT65 Turret and Live Tooling are standard on Haas Y-Axis lathes (ST-20Y through ST-35Y), and optional on non Y-axis models.
