A Drag Finishing Machine is an automated tool for grinding, deburring and polishing of precision parts. They can be used for a range of applications and are suitable for use with all metals, from precious metals to titanium and also plastic components.
How a Drag Finishing Machine Works
A drag finishing system has a carousel that is equipped with multiple workstations. Each workstation is lowered into a bowl filled with grinding or polishing media, and then the components are dragged through the media.
The action of dragging the parts through the media is much more powerful than conventional mass finishing systems, and this makes it ideal for deburring, edge smoothening and high gloss polish. However, this method cannot produce a satisfactory surface finish without the right media.
Different abrasive media is available that can be used to provide a range of finishes from coarse grits for aggressive deburring and edge breaking to finer grits to give mirror polished surfaces. Choosing the correct abrasive media for a given task is vital as it will ensure that any burrs or sharp edges are completely removed from the workpieces and not just bent over.
The machine is equipped with a control board and switches to allow the operator to select the desired speed for the finishing process. The operator can choose lower speeds for finer finishes, and higher speeds for aggressive deburring and edge breaking. The speed of the spindle is also regulated to enable the operator to achieve the necessary results with less processing time.
