 1. Product Introduction
ultrasonic impact finishing of metals equipment is an important measure to process workpiece in precision, which plays an important role in modern society. Through half a century development, grinding machine has become one of the most important marks in modern manufacturing area. After extruding and finishing machining exerted by ultrasonic technology, the metal surface roughness minished and the metal surface layer strengthened.
For now, Japan, Britain, Brazil and other countries have improved technology in ultrasonic grinding machine field. Among the rest of those countries, Japan has invented a half-wavelength bending vibration system successfully. The cutter is fixed at the thin end of the half-wavelength bending vibration system. The piezoelectricity ceramic wafer of half-wavelength bending vibration system is designed to be semicircular. There are two ceramic wafers at the upper and lower, which form two semi-circular piezoelectric transducer(piezoelectric vibrator). Miniaturization , Simple structure and rigidity enhancement are its characteristics.
On account of market and technological development request, we developed the ultrasonic impact finishing of metals equipment based on the grinding technology platform in hand. Through a large number of tests and improvements, we are able to accomplish various manufacturing and processing more efficiently. 
2. Working Principle
Combined with ultrasonic technology, and made use of the feature that metal atoms movement accur at high energies and temperatures, the grindng machine puts high frequency drivers on metal surface, thus can extrude and finish metal surface. After processing, surface roughness is reduced to Ra 0.2, even get the mirror effect. Meanwhile, the micro-hardness, abrasion resistance, fatigue strength and fatigue life of the metal surface are improved.
3. Treatment Effect
3.1?The surface finish quality of treated workpieces are improved to 3 classes higher
3.2?Surface hardness is increased by *0~*0%
3.3?The corrosion resistance of treated metal surface layer is improved several times, reaching **0 times at max.
3.4?The stress field of treated metal surface alters, which helps to improve the comprehensive performance of metal workpieces and increase fatigue life by **3 times.
3.5?Fatigue resistance of treated metal surface is increased by **0%***0%.
3.6?Spot pits on metal surface can be removed after treatment, and initial damage of workpiece is reduced.
3.7?Friction drag of treated metal surface decreased by over *5%.
4. Application 
The ultrasonic impact finishing of metals equipment applies to those materials whose  hardness is lower than *5HRC, such as steel, iron, copper, aluminum, stainless steel etc. It can process mechanical axis, piston rod, hydraulic cylinder, brake pad and other precision components. Our equipment is applied in a large number of industries, such as aircraft, automobile, bridge, mechanical spare part processing, oil pipeline, railway, watercraft and other areas.
