 ROTARY TABLE, 4th axis - DC

Dawlish cam structure RollerDrive product or 4th axis as known, is outstanding in accuracy, strength and service life and is zero backlash. The RollerDrive rotary table uses the roller gear mechanism, one of the finest motion control mechanisms available. The unit is constructed from an input shaft (the roller gearcam) and a turret (output shaft) fitted with roller followers. The roller followers are preloaded against a screw-like input shaft to completely eliminate backlash. Using servo motor as the energy source, the RollerDrive series assist your equipment assist your equipment to realize better speed and precision control, withstand heavy cutting force, overcome external disturbances, and greatly improve transmission efficiency and system stability. The RollerDrive table can realize continuous and accurate spinning, stopping motions at any specified position. For example, it can be used to execute the high-demand feeding process in a high-speed punching machine.
