A common deburring machine used for mass-finishing parts is a vibratory deburring machine, or vibratory tumbler, which utilizes abrasive tumbling media to deburr, clean, or polish unfinished or dirty parts or objects. At Vibra Finish, the abrasive media and unfinished or dirty parts are put inside a large drum. The drum vibrates, driving down the contents in a circular motion, mixing everything together. The unfinished or dirty parts are subsequently deburred, cleaned, or polished by friction with the abrasive material.
The kind of deburring, cleaning, or polishing desired and the part characteristics will determine the type, size, and shape of the abrasive media used. Some common types of tumbling media are abrasive steel, ceramic, organic materials, and plastic. These materials can be purchased in a variety of shapes such as cylinders, cones, stars, pyramids, wedges, spheres, ovals, and other forms, depending on the function needed. Openings in the parts will determine the size and shape of the media used. To prevent media lodging in the part, it should be a minimum of 70 per cent of the size of the hole or slot. This avoids two pieces getting stuck side by side in the piece.
Here are some common uses for abrasive media in the Vibra Finish process:
Abrasive media for deburring equipment wears down slowly, but will vary on how aggressive the media is. Also, the smaller the media, the better the finish, but the longer it will take. The larger the media, the faster it will deburr. Having the correct media and the deburring machine full of parts is the key to successful finishing.
