Precision Nc Rotary Table, 4th Axis Rotary Table

We are offering wds zero-backlash drive technology
wds is a brand under dawlish precision machinery co., ltd, featured by nc rotary table 4th axis series product. Wds roller drives 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. Positioning accuracy reaches as good as 10 seconds.
theory of operation of the roller driver
the roller driver 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. Our proprietary adjustment mechanism provides optimum preload. The roller followers planted in the turret use internal roller bearings to transfer torque while rotating. This ensures zero backlash, outstanding precision, and excellent efficiency without causing wear, while providing long-term consistent accuracy.
Accuracy is consistent with no maintenance even after 4.5 million operation cycles. Long-term use is possible without any mechanical maintenance.
