Fourth- and fifth-axis rotary tables bring added flexibility to conventional three-axis VMCs. At IMTS, Koma Precision introduced the Tsudakoma RG series of rotary tables that uses a ball-drive system for table rotation.
As shown in the photo above, both sides of each ball remain in contact with the system’s worm gear, and each ball is located to within 1 micron of each other. The company says this design offers zero backlash/reversal error while providing a maximum indexing speed of 140 rpm with high accuracy, rigidity and torque transfer. In addition, the device, which is available in three sizes, is said to require no adjustments over its lifetime.
