Below, I will introduce the difference between KK module and ordinary screw module. 1. Positioning accuracy: The positioning accuracy of KK module is higher than that of ordinary screw module, which can reach the 0.01mm level, while the positioning accuracy of ordinary screw module can only reach the 0.1mm level. 2. Friction: The friction force of the KK module is smaller than that of the ordinary screw module, so it is smoother and less noisy during use. 3. Rigidity: KK modules have higher rigidity than ordinary screw modules and can withstand larger loads. 4. Load capacity: The KK module has a stronger load capacity than ordinary screw modules and can withstand larger loads. 5. Update speed: The update speed of KK module is faster than that of ordinary screw module, making it more suitable for modern production needs.
