Runs Cool on Heat-Sensitive Metals
We recommend 3M Cloth Belt 577F for use on aluminum, mild steel, and stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings. To protect heat sensitive alloys such as stainless steel, nickel alloys and cobalt alloys, we incorporated a grinding aid on the belt reduces running temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure. Alumina zirconia fractures frequently to continually produce sharp points and deliver a faster cut-rate than aluminum oxide. A synthetic mineral, it was developed for heavy stock removal and high pressure grinding.
Sized to Suit Your Needs
Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different metalworking applications. At 3M we offer a broad selection of belts to fit most any industrial belt sander. Wider belts are used with wide belt sanders and feed-through style flat finishers to smooth rough-cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts are generally used on a backstand for weld removal or for imparting a finish. Narrow belts can be used on file tools to access right angle corners for finishing.
