The cam meshes with followers equally spaced around the diameter of a roller gear. Needle bearings in the followers provide smooth contact with the cam, and a precise cam profile ensures accurate speeds and motion, the company says. The roller drive is preloaded during assembly, and the system is said to yield high stiffness, torque and speeds while reducing wear and maintenance. The 21-mm (8.3") rotary table provides cutting and indexing speeds ranging to 830 degrees/sec. and maintenance. Constructed of cast iron GGG- Indexing accuracy is ±30 arc-sec. with repeat60, the vise features precision aligning slots and ability of 4 arc-sec. Maximum spindle torque is a positioning hole on the bottom of the vise, as 110 foot-pounds (149 Nm) for synchronous well as pre-machined holes in the vise shoulders fourth-axis machining. A pneumatic break yields 134 foot-pounds (182 Nm) of holding torque for for mounting directly to a table. stationary work.
