Abstract
A method for finishing a surface of a workpiece, having the steps of agitating the workpiece with a first mixture including a first plurality of discrete, homogeneous compressed felt chunks having a first particulate abrasive coating thereon, and then agitating the workpiece with a second mixture including a second plurality of discrete, homogeneous compressed felt chunks having a second particulate abrasive coating thereon with an abrasive size smaller than an abrasive size of the first particulate abrasive coating.
Claims7
A method for finishing a surface of a workpiece, comprising the steps of:
- first agitating said workpiece with a first mixture including a first plurality of discrete, homogeneous compressed felt chunks having a first particulate abrasive coating thereon;
- and
- second agitating said workpiece with a second mixture including a second plurality of discrete, homogeneous compressed felt chunks having a second particulate abrasive coating thereon, said second particulate abrasive coating having an abrasive size smaller than an abrasive size of said first particulate abrasive coating.
An article having a finished surface, said surface being finished by the steps of:
- first agitating said article with a first mixture including a first plurality of discrete, homogeneous compressed felt chunks having a first particulate abrasive coating thereon;
- and
- second agitating said article with a second mixture including a second plurality of discrete, homogeneous compressed felt chunks having a second particulate abrasive coating thereon, said second particulate abrasive coating having an abrasive size smaller than an abrasive size of said first particulate abrasive coating.
