I just bought a new haas tl 1 I need an automatic 3 jaw chuck for it. I am going to be doing lots of facing operations and chamfering. I dont want to use a collet because it is on lots of different size parts. I saw some pneumatic ones is there a good one that doesnt cost 8 grand or is there a hydraulic one that is affordable. I would like to spend around 3 grand if possible
It sounds counter-intuitive, but add TWO-jaw power to your search as well. The top jaws being accurately tooled, they do "round" parts just fine, and odd parts - even asymmetrical shapes - too. It's all about the top-jaws.
Makers are many, power chucks. It's where all the
money went as CNC took over. All the old-line manual chunk makers moved-up and survived, (Schunk, Rohm,) plus others who have always been powered mavins (SMW-Autoblok, Kitagawa, Samchully...)
Used are legion. Even just a
rebuild can be a costly service, so I'd expect high wear is what put them into the used market, and be careful if you go that route. But rebuildable they most certainly are. Most are ramp/wedge or lever actuated
BE AWARE.. that many of these have VERY short strokes! They are meant for the top-jaws to be adjusted (see fine serrations instead of single-dovetail) and/or machined, even ground.
Not many of them can take a "wide range of parts" without that monkey-motion of a new setup for each. Very different from full-range scroll-operated manuals. OTOH, that's part of why they are more accurate, clamp better, stand borderline INSANE RPM (balancing levers inside) and stay accurate longer for high-volume runs of parts.
Not sure I'd discount collets, either. There are some seriously capable and flexible systems out there in CNC-land. Some are familiar - may also have been commonly seen on manuals. Others, hardly-ever.
I'm not selling these, but have a look at the Ortleib "Quadra" for multiple collet types, multiple configurations, double-ended support included, all from one "mothership".
