Why Choose a Harmonic Servo Rotary Actuator as the Drive System for a Five-Axis Rotary Table?
The core requirement of a five-axis rotary table is to achieve continuous and smooth cutting of complex spatial surfaces. This demands that the rotary table not only withstand cutting forces but also exhibit extremely high rigidity and absolute zero backlash. The Harmonic Servo Rotary Actuator fundamentally eliminates issues such as backlash, wear, and elastic deformation inherent in worm gear systems, making it the optimal choice for high-end five-axis rotary tables.
Worm Gear vs. DD Motor vs. Harmonic Servo Rotary Actuator
Five-axis rotary tables can use worm gears, DD (Direct Drive) motors, or rotary actuators as drive systems. So, what are the differences?
Worm Gear
Worm gears are simple in structure and low in cost, with self-locking capability. However, their accuracy degrades over prolonged use. They are suitable for low-end, economical five-axis machine tools.
DD Motor
DD motors have no gear transmission, achieving zero backlash and high accuracy. However, for the same size, they offer low torque density, poor servo rigidity, and high installation and maintenance costs. They are suitable for OEMs with strong in-house R&D and integration capabilities, requiring significant resources to address integration issues.
Harmonic Servo Rotary Actuator
Harmonic Servo Rotary Actuators are typically used for the A and C axes of five-axis rotary tables (which consist of three linear axes and two rotary axes). They offer high precision, long service life, and low noise. They are the best choice for high-end five-axis machine tools, providing the most reliable solution when considering precision, rigidity, and speed comprehensively.
