The RNA-S, RBA-S and RBA-K, S series rotary tables have an indexing speed ranging to 88.9 rpm. These high speed rotary tables are said to increase productivity not only by decreasing cycle times, but also by enabling smoother surface finishes, thereby reducing secondary machining requirements.
The rotary tables generate a torque transfer efficiency ranging to 85 percent by using an oversized, dual-lead, worm wheel/worm spindle drive train. The worm wheel is made from a proprietary, dense, high-tensile-strength brass alloy with exceptional hardness and vibration absorption characteristics, the company says.
The tables feature massive clamp torque and incorporate cross roller bearings for smooth and powerful table operation, the company says.
The tables guarantee repeatability of ±2 arcseconds and are available with a range of options including rotary scales, pull stud devices, hydraulic and pneumatic rotary joints.
