Workpiece Picture:
Our customer is difficult to micro-drill alumina ceramic (D0.2mm*d3mm) under the quality standard(edge-crack<10um, hole tolerance<0.02mm).
We validated with our CNC machine and the past experience from alumina micro-drilling and successfully overcome the impossible

Comparison of Tool Wear
Nearly no tool wear by sight compared to new tool.

Highlights of HIT Ultrasonic Module
In case of reaching clients’ quality requirements(Edge crack<10um),
üOvercome the Impossible, from zero to available (60 sec/hole)
üHi-Precision Machining Quality(the diameter tolerance of each hole doesn’t exceed +0.02mm)
üProlong Tool Life
