Ultrasonic M2 Threading Al2O3 Ceramic
Ultrasonic Machining of Al2O3 Ceramic : M2 Internal Threading｜Hantop Intelligence Tech.
HIT utilized the ultrasonic machining module for the M2 internal threading on 99.7% Aluminum Oxide (Al2O3). The high frequency micro-vibration of HIT ultrasonic-assisted machining technology allowed for intermittent contact between the tool and workpiece, achieving better chip and cutting heat removal. This greatly reduced tool wear and ensured complete profile of M2 internal thread dimension.

Aluminum Oxide (Al2O3) ceramic has excellent chemical resistance and thermal stability, which makes it widely applied in the semiconductor manufacturing processes (including etching and thin film processes), especially being made into the key components (such as ceramic electrostatic chuck) for wafer foundry.
However, the high hardness and brittleness of aluminum oxide have brought great challenges and difficulties for industrial manufacturers, especially for the machining of M2 internal thread dimension. In conventional CNC machining, the strong cutting force and the constant contact between the tool and workpiece would consequently accelerate and intensify the tool wear. The major diameter of the internal thread became smaller as the thread went deeper. Eventually, the screw could not be fully locked into the thread, resulting in serious impact on the quality of product.
The high frequency micro-vibration of HIT ultrasonic-assisted machining technology allowed for intermittent contact between the tool and workpiece. This greatly reduced the cutting heat produced by constant contact between the tool and workpiece during conventional machining. It also brought easier inflow of the cutting fluid. With better chip and cutting heat removal, the tool wear was immensely reduced. This ensured the completeness of the profile of M2 internal thread and successfully enhanced the quality of workpiece.
