Ultrasonic polishing
The workpiece in the abrasive suspension and put in ultrasonic field, rely on the ultrasonic oscillation effect, make the abrasive surface grinding and polishing. Changshu anhui polishing material co., LTD. Think ultrasonic machining macro force is small, can not cause deformation of workpiece, but tooling production and installation more difficult. Ultrasonic machining can be combined with chemical or electrochemical method. On the basis of corrosion, electrolytic solution, and then applying ultrasonic vibration mixing solution, make the surface lysate from, near the surface of the uniform corrosion or electrolyte; The ultrasonic cavitation in liquid can also inhibit the corrosion process, favors the normal lighting.
See polishing is rely on high speed of fluid flow of liquid and its carrying abrasive erosion surface to achieve the purpose of polishing. Commonly used methods are: abrasive jet machining, liquid jet machining, grinding fluid power, etc. Grinding fluid power is driven by hydraulic pressure, make carry liquid medium to high speed reciprocating abrasive through the workpiece surface. Medium is mainly used in low pressure through the special compound with good sex (polymer materials) and mixed abrasive, abrasive silicon carbide powder can be used.
Finishing grinding
Principle of mirror finishing machine is the use of power line free grinding and polishing, prompting artifacts and abrasive flow in the process of revolution and rotation of the force, thus the workpiece surface micro machining. The operation is simple, abrasive and tooling clip, convenient operation, high efficiency, no noise, no vibration, closed to use. No pollution, environmental protection performance is good, finishing workpiece precision is high, do not change the original geometry size of workpiece, can solve the workpiece precision deburring, chamfering, mirror finishing polishing machine and other problems.
