Attachments can even mimic the principles of centerless grinding and provide unique fully spherical ground features. In addition, the surface grinding method known as creep-feed grinding allows a large amount of material to be removed in a single, slow pass of the wheel rather than a series of fast, tiny, lateral cuts.
