[0002] Conventional processing technology can no longer meet the market's requirements for mass production of hard and brittle materials, titanium alloys, stainless steel and other high-end difficult-to-process materials, and there are problems such as poor surface quality, low efficiency, and short tool life. Ultrasonic processing is widely used in the processing of non-metallic, hard and brittle materials and small and deep holes because the tool tip has ultrasonic energy.

In order to avoid the entanglement between the power supply lines, a wireless induction module is usually installed in the ultrasonic spindle to transmit power. The gap between the power supply module and the power receiving module inside the existing spindle cannot be adjusted according to the processing needs. It is inevitable that due to factors such as the cumulative error of parts processing or assembly, the actual gap between the power supply module and the power receiving module after assembly will deviate from the theoretical gap, which will inevitably affect the efficiency of wireless power transmission and thus affect the ultrasonic vibration effect.
