We developed our bore chucking live center for use in our hydraulic cylinder manufacturing. It chucks tubing by the inside diameter. This gives it better concentricity than a Steady Rest. It also has a faster set up time, and is easier to use. The face end off, machine OD, chamfer OD, bore ID, and chamfer ID can all be ran with one set up, and parts can be ran at a higher RPM. All of which leads to increased productivity.
Minimum bore is 2.99” without shoes. Shoes are available in steel, aluminum, and aluminum with a plastic band for IDs from 3.250” (80mm) to 7.1” (180mm)
