Although not nearly as common as 3- or 4- Jaw chucks, a 2-Jaw Chuck can be quite handy for certain 4th Axis jobs. The jaws on a 2-Jaw chuck are opposite each other (obviously!) and they are driven by a scroll plate, just like the jaws on a 3-Jaw chuck. They are typically used in 2 scenarios:
- Rapid Prototyping - for example, cutting a 3D shape out of a block of plastic or wood with a single 4th axis operation using a ball end mill.
- Holding odd parts - In this case, they are often used with custom soft jaws milled for that purpose
Here's a quick video with Mike C. demonstrating some setup basics when using a 2-Jaw Chuck:
