Rotary Table Series for Vertical Machining

Koma Precision introduces a new line of high-accuracy, high-rigidity, energy-saving and zero-maintenance rotary tables from Tsudakoma. The Rotary Ball System (RBS) is a 4th-axis rotary table series suitable for single-axis VMCs. The Tilt Ball System (TBS) is a 5th-axis rotary table series suitable for dual-axis VMCs.

The tables are built using the new ball drive system featuring advantages like zero backlash, improved cycle times, energy conservation and a lifetime adjustment-free transmission system.

Three new models are available for the RBS series. The RBS-160 has a face plate capacity of 6.3" (160 mm). The RBS-250 and the RBS-320 have face plate capacities of 8.27" (210 mm) and 10.04" (255 mm) respectively. The TBS series is being introduced with TBS-130 and TBS-160 models. Both the RBS and TBS series tables are highly rigid and have increased clamp torque delivered by the improved clamp system design. Various options such as chucks, tailstocks, support spindles, and faceplates are available. Pneumatic and hydraulic rotary joints for automatic load and unload of the workpiece are also available.

The ball drive system technology features high-speed indexing and zero backlash that result in shorter cycle times. This new technology also delivers high-torque transmission efficiency.
