The three types of work that centrifugal barrel-finishing machines can do are known as steps. You may not need to perform all the steps depending on the surface finish requirements of your product. There may be one step, two steps or three steps in your process.
Centrifugal barrel tumbling machines are the fastest and most cost-effective method for deburring and/or polishing large quantities of metal parts at once. Also known as an industrial tumbler, rotary tumbler or harperizer system, a centrifugal barrel finishing machine uses a cyclical sliding action to grind the metal surface. Centrifugal barrel finishing is a type of mass finishing.
These machines are suitable for seven-day-perweek and multiple shift operations. The machines were designed with heavy production requirements in mind. They can be used to fulfill large production needs such as deburring and slag grinding, edges radiusing, paint/surface prep, finishing/polishing, or any combination thereof.
A centrifugal finishing machine can increase the consistency of quality. Handwork has a maximum acceptance rate of 80%, but a centrifugal bar finisher can deliver much higher acceptance rates. Additionally, the surface finish of a centrifugal barrel finisher is consistent in all directions. It is not like hand polishing.

The centrifugal barrel tumble machines are particularly well-suited for removing large burrs and blending lines that can be caused by machining. These machines are also excellent for polishing and burnishing. Centrifugal barrel machines can be used with various kinds of ceramic or organic media (e.g. corn-cob), and can achieve almost any surface finish, from super-fine polishing to burr removal.
A centrifugal barrel tumbling machine works on the same principle as a Ferris-wheel, but has smaller baskets that are attached to the edges. The centrifugal finishing machine or harperizing systems has 4 barrels. Each one represents a seat in a Ferris wheel. One large flywheel is also included. Each revolution of this flywheel produces one complete rotation for each barrel. The flywheel rotates quickly and produces extremely high centrifugal pressures, up to 15 to 20 times greater than the force of gravity. Under high pressure, the contents slide against each other. The increased pressure allows fast processing of metal parts as well as consistent and smooth finishes.
A centrifugal barrel part tumbler can reduce 95% of the work required to deburr or polish parts by hand. This reduces the amount of manual sorting and greatly increases production and returns on investment. The use of a centrifugal finisher to remove and identify any defects or burrs from each piece reduces the time and cost of using a microscope.
Polishing is usually a dry process with ground-up corncob used as media. The compound embedded in the polishing agent is included. Also, dry processing can be made with ground-up walnutshells.
Don’t forget the detergent. You might think that cleaning compound was intended for the metal parts, but in fact the tumbling media needs it. Cleaning compound adds lubricity to keep the pores open in the tumbling media. Once the pores in tumbling media become glazed over, the cutting action of the tumbling media will no longer work and metal parts turn out black. If the parts come out black, you forgot to put in the soap.

These machines are designed for multi-shift and seven-day-per week operations. This machine is designed for the highest production requirements to enable you to meet large production demands.
The centrifugal bar finishing machine is versatile and is used in many different industries for metal finishing.
Finishing mortars and concretes; natural and artificial masonry materials; decorative ceramics; materials and items made of wood, paper, glass, plastic, and metals; and paints and varnishes are the most common finishing materials used in modern construction.
Finishing processes can be used to improve the following characteristics: appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control surface friction.
