Rubberized Abrasives Catalogue

Grit Textures
Each Cratex size and shape is made in four standard Grit Textures or compositions which differ in accordance with the mesh size of the abrasive grain used. [C] COARSE (Green) [M] MEDIUM (Dark Brown) [F] FINE (Reddish Brown) [XF] EXTRA FINE (Grey Green)

Cratex Standard Bond
The Cratex bond common to each of the four Grit Textures is made with premium grade oil-resistant chemical rubber. In contrast to conventional grinding wheels the Cratex bond has unique cushioned action...cuts freely, smoothly and softly without gouging or digging into the work surface. It resists clogging or smearing, and is ideal for a broad range of applications where metallic or non-metallic surfaces must be smoothed and polished without loss of dimensional tolerances or control.

Cratex Abrasive Type
The abrasive type used in Cratex Rubberized Abrasives is premium-quality Silicon Carbide that has been washed, dried and treated to remove impurities and then carefully screened to U.S. Department of Commerce standards for size. Although silicon carbide is more expensive than other abrasive materials, it is used because it has a high level of purity and has been found to be best for the broadest range of light deburring, smoothing, cleaning and polishing applications on ferrous and non-ferrous alloys as well as many non-metallics, such as glass.

Shapes and Sizes
The Cratex Wheels, Points, Cones, Blocks and Sticks listed are all available as standard products. The occasional need for non-catalogue shapes or compositions can usually be solved by adapting or modifying standard shapes and compositions to meet special requirements. Several wheels can be mounted in series for added width. The abrasive action of the wheels can be softened by using lower operating speeds and lighter work pressures. Cratex Rubber Bonded Abrasives can also be dressed or shaped to special contours using conventional abrasive wheel dressing tools and methods.

Quality Control
All Cratex Rubberized Abrasives are made and safety inspected to the requirements of American National Standards Institute (ANSI) publication, B7.1 safety requirements for the use, care and protection of abrasive wheels. This publication should be made available to all operators of Cratex products. Copies of this publication are available from UAMA or ANSI listed below:

Basic Applications
Light Deburring and smoothing to relieve stress concentrations and to remove visible and microscopic burrs without impacting surrounding areas.

Smoothing and polishing to improve wearing qualities and to reduce the dangers of progressive fracture and fatigue failure.

Cleaning and polishing to remove undesirable surface deposits.

Polishing and smoothing to improve performance, appearance, cleanliness and to lessen the dangers of surface contamination.

Typical Applications Include:
Breaking edges, radiusing and polishing out high spots, removing rust, cleaning threads, smoothing the edges of punched or sheared metal, deflashing, smoothing and polishing molds, dies and other production tools, sharpening and honing of cutting dies, blades and edged tools, removing corrosion, excess solder, heat marks, cleaning and polishing contact points, jacks and electrodes, removing tool marks, scratches light burrs, and fins, blending in welded seams after rough grinding, engine turning, damaskeening, polishing engine ports, shafts, turbine blades, smoothing glass edges, jewelry finishing, gem stone sanding and many others.

Cratex Rubber-bonded Abrasives are used in a widely diversified list of industries, on production and assembly lines, in finishing operations, in tool and machine shops, in the production of basic tools, instruments, component parts and for maintenance and repairs.
