The working principle of the KK module is that the motor is connected to the rotating shaft through a coupling to rotate, thereby driving the lead screw to rotate. The lead screw nut seat controls the direction to move back and forth. The KK module is called the "noble" among linear modules mainly due to its structural features, performance advantages and price.

1. Modular design: Through modular design, KK modules integrate ball screws and linear guides, using high-precision ball screws as the transmission mechanism and optimally designed U-shaped tracks as the guiding mechanism, ensuring the requirements of precision and rigidity.

2. Compact structure and easy installation ‌ : It adopts an integrated design of guide rails and U-shaped body, integrating the functions of ball screws and rolling guide rails. This avoids the complexity of selection, installation and commissioning in traditional applications, and saves space.

3. High precision and high rigidity ‌ : The KK module achieves the best rigidity-to-weight ratio through an optimized structural design using the finite element method, featuring high precision and rigidity. Its repeat positioning accuracy can reach ±0.01mm, and the precision level can reach ±0.003mm.

4. High load capacity ‌ : The design of the KK module enables it to maintain stable performance even under high loads, making it suitable for applications that require high loads and high precision.
