The 5 AX-200II CNC rotary table from Lyndex-Nikken is said to provide accuracy and fast rotating and tilting speeds. The company says its carbide worm system ensures wear resistance, rigidity and the rapid speeds.
The worm system uses a carbide worm screw and an ion-nitrided worm wheel rather than a conventional bronze or bronze alloy actuation mechanism. According to the company, this reduces friction, wear and backlash. This reduces backlash when compared to standard bronze worm gears. 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 to 60 Rc, enhance system rigidity and longevity, the company says.
Allowing for the machining of five sides of a workpiece, the table is suited for medical and aerospace five-axis work. The faceplate diameter is 200 mm, and the maximum work load is 176 lbs.
