Today, 3M develops wheels with new and advanced technology while continuously improving its existing product line. Customers choose Scotch-BriteTM surface conditioning wheels because of their ease of use and consistent results. In addition, to assist in increasing productivity, customers are supported by dedicated Technical Service teams and 3M Innovation Centers around the world. Scotch-BriteTM Wheels * Can improve surfaces without significantly changing the shape or dimension of the workpiece. * Are well-suited for an array of cleaning, blending, deburring, finishing and polishing applications. * Help prevent undercutting or gouging through their controlled abrasive action. Selecting Convolute vs. Unitized * Provide consistent, uniform finishes as fresh abrasives are continually exposed to the work surface. This choice will often be determined by the part configuration, wheel size availability, tool speed or other fixed circumstances. * Run cool and resist loading due to their open web construction, which reduces the risk of part discoloration and warping, while extending the life of the wheel. Convolute is a wrapped construction on a standard sized core and the "flat" of the web becomes the cutting tool. The wheels are one directional, which is indicated by an arrow on the side of the wheel and arrows printed in the core. Factors to consider when choosing a starting point for your application Unitized is a layered construction with a selection of center hole sizes and no core. The "edge" of the web becomes the cutting tool. The wheels are non-directional. See Convolute and Unitized equivalency chart on page 25. * Composition of workpiece and material type * Material hardness * Desired results to be achieved Basic Performance Differences * Size and shape of the work piece (area to be conditioned) Construction Finish Density Size * Tool/machinery type, including speed capability Wrapped construction on a standard sized core.

See pages 23-24 for recommended flanges/accessories. 7 Convolute / Molded Wheels Scotch-BriteTM SST Deburring Wheel Scotch-BriteTM SF Finishing and Deburring Wheel SST Deburring Wheels are designed for deburring on most stainless steel, titanium and other demanding alloys. Burrs from drilling, stamping, punching and other machining operations can easily be removed with SST wheels. The SF Wheel is loaded with mineral that is smear resistant yet durable when exposed to metal burrs. This results in a wheel that delivers excellent finishes while still handling burrs. In some applications, this wheel can handle three surface modifying elements -- combining finishing, deburring and blending into one operation. Unlike some higher density products, SST wheels are somewhat softer and more conformable, making them ideal for use on more intricate shapes and contours. SST wheels are used extensively in the aerospace industry for deburring and finishing parts, and for finishing cast and threaded products used in medical and surgical applications. The SF wheel's unique resin construction allows it to run smooth and resist chunking while requiring less frequent dressing. It is an excellent option when finish is critical on deburring applications.

See pages 23-24 for recommended flanges/accessories. 8 Convolute / Molded Wheels Scotch-BriteTM Cut and Polish / CPM Wheels Scotch-BriteTM Metal Finishing Wheel Cut and Polish / CPM Wheels are heavy duty wheels for more aggressive blending and finishing. These long lasting wheels perform well on tough blending and finishing applications such as removing surface defects, coarse grindlines, blending forging marks and machining mismatches while leaving a uniform grain finish. Highly conformable Metal Finishing Wheels are designed to apply uniform and consistent satin/antique finishes. They are used effectively to blend and match #3 or #4 mill finishes on stainless steel and to create brushed or satin finishes on cutlery. Cut and Polish / CPM Wheels are very similar but have subtle variations. The CPM Wheel is slightly harder and more aggressive in demanding applications. On softer metals such as aluminum, copper and brass, they are used to blend out minor surface imperfections and handling marks while providing the desired decorative finish. Both wheels can demonstrate value in a variety of applications, and are especially well suited for centerless finishing.

Similar to the EXL Convolute Wheels (EXL, EX2, EX3 Deburring Wheels) they resist smearing and minimize heat buildup on the workpiece. Scotch-BriteTM RolocTM EXL Unitized Wheels are strong and efficient for edge deburring and finishing. They perform well in a variety of metal working applications and machined parts where close tolerances are important. There are a wide variety of densities and grades available starting from a very soft 2 density for applications requiring a conformable product extending to a hard, aggressive 8 density for maximum cut and durability. Changing wheels is quick and easy with RolocTM TR, RolocTM TS, or RolocTM + holding systems. They allow for use of both the edge and surface of the wheel without interruption of mounting hardware. The mounting system is interchangeable with Scotch-BriteTM Surface Conditioning Discs and Coated Abrasive Discs.

The unitized version of the SST wheel is recommended when the application requires very narrow widths and/or small diameter ranges. Cut and Polish Unitized Wheels are long lasting and aggressive for heavy duty blending and finishing with uniform results. The layered "unitized" construction of this wheel provides an excellent starting point for jobs requiring the availability of small diameters and narrow widths. SST Unitized Wheels run well on equipment such as bench motors, floor lathes and portable power tools. These wheels show value in the industry as they can often be used to replace many conventional abrasive products such as rubber bonded wheels and small set-up wheels.

These wheels are available in small diameters and narrow widths. In essence, they provide durability and value for finishing of parts that are too narrow, tight or small to finish efficiently with wider width wheels. Scotch-BriteTM Clean and Strip Unitized Wheel products are excellent for heavy duty cleaning applications. The extra coarse silicon carbide mineral combined with a tough synthetic web is perfect for removing scale, rust, surface contaminants, paints and coatings. They are also well suited for removing weld discoloration and splatter. The open construction and the aggressive properties provide a smooth running wheel that resists loading when removing soft coatings.

Designed for applications requiring fine finishes or light cleaning, the General Purpose Unitized Wheel also tends to be a good starting point when the part shape or size calls for small diameters or narrow width product. Buff and Polish Unitized Wheels are a unitized constructed, non-abrasive carrier for compounds used for polishing flat and symmetrical contoured surfaces. They can often replace felt or leather wheels, as they hold more compound with even distribution allowing for faster cut and less frequent compound application.

Coolants, like water and some water soluble oils, reduce heat and extend product life while providing a greater cut. In the case of most oils or tallow lubricants, surface roughness can be reduced. The higher viscosity lubricants produce lower surface roughness, i.e., grease produces a finer surface finish than oil. In automatic or semi-automatic operations, it is desirable to use lubricants or coolants whenever possible. Generally, low speeds are desired for generating very uniform satin finishes, for finishing aluminum alloys without lubricants, and for use on composite or other soft material applications. High speeds are recommended when it is desired to remove or blend surface imperfections and tough burrs. This high speed will result in a faster cut along with finer finishes. Recommended Operating Speeds (SFPM = Surface Feet Per Minute) Decorative finishing Composites/Soft materials Deburring Blending / Polishing 500-3000 SFPM 1200-2700 SFPM 5000-6500 SFPM 6000-8000 SFPM Product Hardness (Density) 3MTM Wheels are available in a number of densities or hardnesses. Generally, the softer products (2, 3, 4, and 5 density) are used for decorative finishing. They will conform more readily to surface contours along with generating a more uniform finish.
