Finishing Equipment

Finishing Equipment can take on many different shapes, and types of finishing processes. Depending on the parts you are finishing, the quantity of parts, type of material, the cost to produce the finish, and the final finish you are trying to achieve, will determine which finishing equipment you will use, and the process you will need to achieve the finish you want.

I have listed and shown below just a few of the different types of Finishing Equipment available today. A brief description of the finishing equipment, and why you may choose to use that type of finishing equipment.

Centrifugal disk Finishing Equipment, is one of the faster pieces of finishing equipment available today. It is limited to small and medium sized parts, due to the torroidal action developed between the bottom Disk and the Tub side wall. These finishing machines can be stand alone like the one shown, or complete systems with automatic part loading and unloading, media and part separation and media reloading. Disk finishing equipment is limited also with the size of media that can be used in it due to the Gap between the disk and tub wall. Most manufactures do not recommend using very small medias. Disk finishing equipment can be used for aggressive part deburring to very fine jewelry finishing. Disk finishing equipment can reduce conventional Vibratory bowl process times by as much as 10 to 20 times.
Tub Type Vibratory Finishing Equipment are used for parts that do not lend them selves to bowl type finishing equipment, due to the parts size, length, weight, etc. Tub type vibes can have dividers in them, to keep the parts from contacting each other during processing for better finishing. Large parts may be fixtured as to keep the part from bottoming in the tub and to improve the surface finish during processing. Turbine Blades and exhaust headers, are examples of fixtured parts in Tub Type Vibratory Machines.


Horizontal Tumble Finishing Equipment offers the lowest cost per piece of all finishing systems available. Fast radius generation as well as low RMS surface finishes may be obtained. Tumble finishing machines produce a constant free-flowing mass of parts and media resulting in an extremely high rate of cut to remove burrs and improve surface finishes. All parts and medias are constantly in a tumbling circular motion. Both wet and dry processes may be used in Tumble Finishing Equipment.


Cob Meal Dryers are used for drying parts that have been vibratory deburred or polished or tumble finished thru finishing equipment. They can be used alone, or in conjunction with other vibratory finishers. A normal system could include one or two vibratory bowl finishers feeding one Cob Meal Dryer. The normal sizing for a Cob Meal dyer is half the size of the finishing bowl that is feeding it. Cob Meal Dryers may be heated with ceramic core heaters or closed loop heated circulating fluid systems for safety.

With in the range of equipment listed above the following finishing medias can be used, Ceramic finishing Media, Plastic Resin Finishing Media, Synthetic Plastic Finishing Media, Corn Cob Finishing Media, Walnut Shell Finishing Media, Steel Finishing Media and Loose Grain Finishing Media.

In addition to the equipment and the Mass Finishing Media you are using, a good Finishing Compound should be used, to keep the parts your finishing clean, and the media in proper condition for burnishing or deburring. The following are some examples of Finishing Compounds you could use, Alkaline Cleaner, Acid Burnishing, All metal cleaner/inhibitor, Anti-Rust.
