NON-BACKLASH ROLLER CAM TYPE
YOUZHI's high-speed cam-driven AR rotary table provides high-speed cutting and indexing. It has high-precision spindle torque for simultaneous 4-axis machining, and a pneumatic brake that provides holding torque for stationary operation. The graduation accuracy is ±20 arc seconds and the repeat accuracy is 4 arc seconds.
YOUZHI's AR Series 250 mm discs have a center height of 160 mm, a through hole depth of 75 mm, a plate-like T-slot of 12 mm, six radial T-slots to simplify fixture and workpiece mounting, and manual and pneumatic tailstocks available For extra work piece support. The high-performance roller cam system uses a high-torque servomotor to drive an arc cam that meshes with a cam follower equally spaced around the diameter of the roller gear. The needle bearing in the cam follower provides smooth contact with the cam, and the precisely designed cam profile ensures accurate speed and movement. Because the roller drive is preloaded during assembly, the system has high stiffness, high torque and high speed while providing low wear characteristics and reduced maintenance.
