Surface Finishing

Vibratory Tumblers

Vibratory TumblersDesigned for mass finishing with ceramic, plastic or synthetic media. Achieve consistent finishes with minimum down time. Bowls are large heavy polyethylene, reinforced for durability, and provided with easily removable covers for in process inspection. All models have ball bearing motors, with thermal overload protection, and valves with a strainer for fitment to an optional flow through (FT) system.

Magnetic Finishers

An ingenious, new approach to the mass finishing of work pieces that have cuts, slots, recesses and filigree. Achieve excellent results with freely moving micro stainless steel pins and balls, that create numerous impacts by centrifugal motion. Features fixed or variable speeds, manual or programmable. All models have see through bowls with a cover for easy loading. Complete instructions included. All programmable finishers have a variable speed control and a forward/reverse switch selector.

S/Steel Magnetic Pins & Balls

S/Steel Magnetic Pins & BallsMade of quality material, these micro pins and balls must be used with a small amount of burnishing compound and mild detergent in magnetic finishers. For finishing delicate jewelry, use steel balls that rotate gently within the bowl.

Rotary Tumblers

Rotary tumblers are stable well balanced units that are capable of processing larger work pieces with heavier media. Process times are longer than vibratory finishing, but a distinct advantage is that the surface of work pieces get work hardened. Barrels are multi sided, made of tough polycarbonate, leak proof and will not corrode or rust. Use with all types of media including steel shot. Addition of burnishing compound and detergent, keeps parts cool and avoids drag during tumbling. Features include variable speed, a programmable timer, forward/reverse and auto shut off with buzzer.

Steel Shot& Stainless Steel ShotSteel Shot& Stainless Steel Shot

Steel Shot: 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: Unlike carbon steel, this media needs no rust protection. Heavier in weight and corrosion resistant, these 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.

Cyclone Sand BlasterCyclone Sand Blaster

The sand blaster is an air tight plastic cabinet within which an air jet forces blasting media, either glass beads or aluminum oxide, on to the article to remove hardened investment or to generate a smooth surface. The cabinet is one piece molded and resistant to rust or leakage. Blasting media is automatically re-circulated. An air pressure regulator allows variation in the applied blasting force. The blaster includes a convenient easy viewing glass with the additional benefit of an internal light. A double filter system eliminates the dust particles from contaminating the environment. Operates on 60-80 PSI. (Compressor not included).


Blasting MediaBlasting Media

Surface preparation is of vital importance before polishing, burnishing and plating. Surface roughness may be improved by blasting with media, either abrasives or glass beads. Different surface finishes may be generated by varying the parameters of the micron size of abrasives and air pressure. The degree of matte to satin finish depends on the hardness of the material being finished.
