Unique Advantages of Ultrasonic Machining

• Ultrasonic vibration at the tool tip (15–70 kHz)
• Reduces microcracking
• Lowers cutting forces and improves process efficiency
• Extends tool life
• Minimizes burr formation
• Improves surface finish

Application Cases

• High-precision machining of hard-brittle materials (ceramics, sapphire, glass, silicon carbide)
• Machining of carbon-fiber composites and superalloys (e.g., titanium alloys)
• Small parts machining and micro-hole drilling
