CNC Rotary Table
NON-BACKLASH ROLLER CAM TYPE
The roller cam consists of an input cam shaft and a roller turret.
The roller cam is designed with rolling contact, featuring high rigidity, high speed, and outstanding durability.
Engagement between the roller and cam are preloaded to fully eliminate backlash that enables the roller and cam to exhibit their ultra-high precision feature.
Besides, with rolling contact to transmit kinetic energy, energy consumption during drive can be dramatically reduced. This enables the roller cam to achieve over 90% of transmission efficiency.

Roller cam advantage
Roller cam
Roller cams are used in linkage cutting to better highlight the rigidity of cutting, and the four-point rolling contact surfaces on both sides are restrained.Extremely low backlash between the roller bearing and the cam enables high machining accuracy and fine surface roughness.
Worm and Gear
Worm and gear transmission method, because the actual contact surface is only single-toothed, single-faced, linked cutting machining, cutting rigidity is weak, due to long rotation, worm gear tooth surface wear, disc backlash gradually increased, machining accuracy
Index plate comparison
Temperature test
The test was run from AM 08:00 and each indexing disk was run for 2 sec until PM 17:00 ended.
The test confirmed that the low friction drive has high efficiency and the oil temperature is not easy to increase.
