® 17. Steel Shot & Stainless Steel Shot SURFACE FINISHING Steel Shot (C.S): Made of carbon steel in various shapes, but uniform in size. Fine shot is the ideal choice of media for burnishing. It is a proven fact that the addition of tumbling powder, moistened with burnishing compound, helps to prevent rust on the steel shot. The tempered steel shot will impart a uniform, scratch free, work hardened surface on all metals. After use, carbon steel shot must be rinsed clean and stored in a rust preventive solution. Stainless Steel Shot (S.S): Unlike carbon steel, this media needs no rust protection. Heavier in weight and corrosion resistant, this shot may be safely used with acid soap solutions. Selection of the shape is determined by the form of the work pieces. Pins are the ideal choice for finishing intricate cavities and filigree. This media must be cleansed in water, then dried and stored.

The heavy or medium cut is a reflection of the particle size of the abrasive. Triangular media eliminates jamming and is designed to reach into grooves, corners or shallow contours. Cylinder shapes with their gentle rolling motion may be used in a secondary operation to smooth the surface. Keep the media moist during tumbling by adding a burnishing or a light soapy compound. Sold bx/50 lb 18. Ceramic Media 19. Plastic Media Plastic bonded abrasive pellets are an excellent choice for providing a uniform finish on medium hard or soft metal. Improve surface finish gradually from coarse to fine. Blue pyramids (fast cut) are best for the initial stage. Green pyramids (general purpose) leave a smooth matte finish. Lt. Green pyramids (smooth finish) will impart a high shine.

When running conventional media that require a wet process, be sure to have the correct amount of water and compound. Excess water will hamper the vibratory action thus giving less than the desired results. Media and compound should be just wet with no standing water. Use of a compound rinsing system will ensure proper dispensing of water and compound. © Copyright 2008 285 previous page next page
