Haas HRC210 roller cam rotary table offers 4th-axis boost to productivity

The high speed, cam-driven HRC210 rotary table from Haas provides cutting and indexing speeds up to 830°/sec. It has 149 Nm of spindle torque for synchronous 4-axis machining and a pneumatic brake that yields 182 Nm of holding torque for stationary work. Indexing accuracy is ±20 arc-sec, with repeatability of 4 arc-sec.

The Haas HRC210's 210 mm platter has a centre height of 152.40 mm, with a 50.8 by 48.5 mm deep pilot bore and 45 mm through hole. Six radial T-slots simplify fixture and workpiece mounting, and both manual and pneumatic tailstocks are available for additional workpiece support. A high performance roller cam system uses a high torque servomotor to drive globoidal cam meshing with cam followers equally spaced around the diameter of a roller gear. Needle bearings in the cam followers provide smooth contact with the cam, and a precision-engineered cam profile ensures accurate speeds and motion. Because the roller drive is preloaded during assembly, the system yields high stiffness, high torque, and high speeds, while providing low wear characteristics and reducing maintenance.
