Potential uses for random orbital sanders in aerospace manufacturing include: Sanding airplane skins, polishing windows and windshields, sanding titanium, aluminum, and stainless steel parts in the paint shop, as well scuffing, buffing, and final finishing work. In MRO applications, air powered DA sanders excel at: window glass repair and polishing, stripping and painting sidewalls, ring refurbishing, removing oxidation and scratches from parts handling, and taking off paint from the engine cowling, stabilizers, nose cone, and rudders.
When selecting an air powered orbital sander for your application, ask yourself the following:. How aggressive of a cut is required? Will hook and loop velcro style or sticky PSA style sanding discs be used? If dust capture is a major concern opt for a hook and loop style sander as there are more dust free abrasive options available for this style.
Dust Capture or Plain? The Dynafile is a portable hand held belt sander that accepts a wide variety of contact arms, belts, and accessories. The purpose of the Dynafile is to allow for the completion of multiple jobs with just one tool.
The contact arm attachment that holds the belt is spring loaded which allows for fast, tool free belt changes. The dynafile is designed to grind, deburr, blend and polish, on metal, plastic, fiberglass, composites, rubber, and glass. When used with a non woven belt Scotch Brite , the Dynafile is also highly effective at blending turbine blades.
Regardless of the application, you can choose to grind with the contact wheel, grind with the platen pad, or finish and polish using the slack of the belt. What makes the dynafile so versatile however, is its ability to accept a huge variety of available contact arms all designed with a specific application in mind. In aerospace, the Dynafile is particularly useful for grinding down the backs of rivets, blending welds, and surface conditioning prior to painting.
Additional benefits of the Dynafile include the ability of the motor housing to be rotated in order to position the throttle lever in the position that is most comfortable to the operator. The Dynabrade Dynafile is compatible with both coated and non-woven belts. The chart below provides just a small sample of the contact arms on offer:. Perhaps the most widely used air tool, die grinders are widely used in aerospace manufacturing for both light deburring and heavy material removal applications.
Inline die grinders are well suited for applications in confined areas, while right angle die grinders provide greater torque under load when more aggressive material removal is necessary.
Die grinders are perfect for removing corrosion and paint without damaging sensitive aircraft materials. This setup provides a lower profile tool for accessing restricted areas. When selecting an inline or right angle die grinder for your application, be sure to select the orientation that allows the best access to the work.
For example, if the goal is to deburr the bottom of a blind cylindrical casting , an inline die grinder with an extended neck and perhaps an extended carbide burr is in order. Conversely, if you are working parting lines on the outside of the same part , an operator would just use a basic right angle die grinder. When selecting the horsepower of your die grinder you need to be conscious of the amount of material to be removed. Customer Reviews. Our Blog Read all Blogs. Posted by Mark W.
