KOMA Precision Inc. introduces a line of high accuracy, high rigidity, energy saving and zero maintenance rotary tables from Tsudakoma. The pictured RBS series (Rotary Ball System) is a 4th axis rotary table series suitable for single-axis VMCs and the TBS series (Tilt Ball System) is a 5th axis rotary table series suitable for dual-axis use on VMCs.
These rotary 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, with face-plate capacity of RBS-160 being 6.3" (160 mm), RBS-250 with 8.27" (210 mm) and RBS-320 with 10.04" (255 mm). The TBS series is being introduced with TBS-130 and TBS-160 models. Both the RBS and TBS series tables are rigid and have increased clamp torque delivered by the new 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 new ball brive system technology features high speed indexing and zero backlash that result in shorter cycle times. This new technology also delivers high torque transmission efficiency.
Reaction in dynamic motion systems where potential energy that was created while the object was in motion is released when the object stops. Release of this potential energy or inertia causes the device to quickly snap backward relative to the last direction of motion. Backlash can cause a system’s final resting position to be different from what was intended and from where the control system intended to stop the device.
