Recommended Operating Speeds
One of the factors that most directly impacts the performance and ultimate success of any abrasive product is the use of the right surface speed for the application. Lower speeds are generally suggested for creating uniform satin finishes and for working on composites and soft materials such as aluminum. High speeds are recommended for deburring, and for removing and blending surface imperfections when faster cut rates and finer finishes are required.
Chemical Resistance
Non-woven materials should not be used around or exposed to organic solvents, strong acids and alkali solutions.
Lubricants & Coolants
Although Marvel non-wovens can be used wet or dry, the use of lubricants and/or coolants can enhance performance variables such as product life, cut rate and heat generation. Typical solvents and/or coolants include water, oil and grease. We suggest the use of our Marvelube product, whose features and benefits are described in our catalog.
Note: For Speeds and diameters not shown use this equation to calculate any surface speed. FPM = Pie x Dia. (Inches) x RPM/12
How to Select a Flap Wheel Width
In choosing a width for a flap wheel it is a good idea to be slightly over the width of the part to be polished. This allows the wheel to groove slightly and make it easier to run production.
