The 5AX-200II CNC rotary table from Lyndex-Nikken is said to perform with high accuracy and fast rotating and tilting speeds. The company’s patented carbide worm system ensures wear resistance, rigidity and the rapid speeds of this rotary table.
The carbide worm system uses a carbide worm screw and ion nitrided worm wheel rather than a conventional bronze or bronze-alloy actuation mechanism. This reduces friction, wear and backlash. The worm screw consists of a less-brittle, V-grade form of carbide, while the worm gear is ion nitrided to a depth of 0.1 mm and an external surface hardness of 68 Rc. These properties, as well as a steel way hardened to 58-60 Rc, all work to enhance system rigidity and longevity.
Allowing for the machining of five sides of a workpiece, the rotary table is ideal for medical and aerospace five-axis work, the company says. It features a drop trunnion and clamping torque of 588/490 Nm. The diameter of the face plate is 200 mm, and the maximum workload is 176 lbs. The rotary table is said to offer secure and accurate gripping capability. Various options are available to meet workholding, fixturing and chucking requirements.
