RPS’s RUV-400S stands out as the world's first ultrasonic air-bearing spindle, distinguishing itself from competitors. The basic machining principle of ultrasonic spindles involves vibration in the Z-axis direction at frequencies reaching tens of thousands of times per second, resulting in minimal particle emission during hole machining compared to conventional tools. This makes ultrasonic spindles advantageous.
By incorporating air-bearing spindles, RPS achieves higher rotational precision, stable vibration levels, and superior rotational accuracy compared to ball-bearing spindles. This results in extended tool life, cost savings, improved surface roughness, enhanced precision through unidirectional drilling, and the ability to process high-strength and difficult-to-machine materials.
