Satin Finish Burnishing Machines

Dec 1, 2012   //   by Bob Warfield   //   Blog, Products  //  No Comments

There’s nothing quite like a really nicely finished metal surface.  Sometimes the machining marks are the look you want (someday I am going to write a little software utility that will pattern those marks for appearance sake!), but more often you’re looking for something a little more refined–typically either a satin or polished look.  Being as lazy as I am, this is also the part of shop work that I am always on the lookout for labor savers to minimize the elbow grease.  Labor saving comes in all kinds of formats, from learning how to use a file properly to having the right power tools on hand.  For example, I have a 12″ disc sander I built and use constantly as well as a couple of those miniature belt sanding air tools where the belt is about a 1/4″ wide and it’s like a file.  I keep a deburring tool permanently chucked up in another air tool as well as having a couple of angle grinders handy that have both an abrasive wheel and a wire wheel.  There’s a blast cabinet, a vibratory polisher (my fave for saving the labor but not for every part or finish), a big 5 HP buffer, a giant drawer full of files in every shape and size, lots of scotchbrite pads, flap wheels, and, well, you get the idea.

Naturally, when I came across these burnishing machines over on the Garage Journal (thanks to Monte for posting about them), I was intrigued.  Here’s a video that shows the idea:

The machine is a hand held power tool aimed at strategically placing scratches on the material with an abrasive to create a satin finish.  They make it easy to change the grits and offer a variety of styles.  I’ve used a random orbital palm sander to apply a satin finish, and they work pretty good, but this tool looks to me like it would be faster and easier, especially for welded/fabricated projects like the one shown in the video.  Here’s a couple more pictures of this type of tool:

These tools are German made and not exactly cheap, but they sure look handy.
