Could any one give me some advice what media and method should be used. There are a lot of companies you can buy from such device.
Anther way is to use deburring machine using scottch bi-directional.
Anyway the both methodes are commonly used in aerospace plants. These types of systems usually employ media that is quite small and can access the finer features of smaller parts such as yours. Additionally, dry process media with micro-fine abrasive materials can be utilized to develop surface finishes that rival that on jewelry parts, if functional requirements should call for it. However, what is your volume of production, what surface finish is required, and is cost a factor. I want to post a question or inquiry of my own.
