What type of media should I use for my parts?

There are three major types of media used in finishing processes and each one is effective for different purposes. Ceramic media is typically abrasive and is used mostly for deburring applications where burr removal is required. Plastic media can be abrasive and is used mostly for finer finishes (lower RA). Steel media is used for burnishing (a type of peening) and to soften edges quickly for hand safety. Each type of media are available in hundreds of shapes and sizes. Ceramic and plastic media are also available in different compositions which are variances in type and size of abrasive grit, thus providing different finishes on parts.
