HZ-160 Centrifugal Barrel Finisher

HZ-60 centrifugal barrel finishing machine with lid open.

HZ-160 Centrifugal Barrel
Finishing Machine

The HZ-160 is a full-sized industrial finishing machine that’s similar to MFI’s HZ-120 model, but with longer and deeper barrels. With over double the capacity of MFI’s wide diameter machines like the HZ-60 and HZ-85, you can finish larger diameter or higher quantity parts for even greater efficiency. Equipped with a cover lift, this model makes lifting the lid off your barrels a breeze.

Machine Type: Wide Diameter
Max Part Size: 20″ L x 11″ D
Barrel Dimensions: 20.625″ L x 11.8″ D
Popular Industries: Automotive, Rubber, Contract Manufacturing & Job Shops

HZ-160 Basic Operation

The HZ-160 Centrifugal Barrel Finishing Machine is a high-energy finishing machine. It uses the pressure and friction created through centrifugal force to quickly remove excess material, polish part surfaces, and create a uniform finish. The finish achieved by the HZ-160 is isotropic, meaning parts are polished uniformly and evenly in all directions, something that cannot be achieved by hand finishing.

Tailored Finishing Speed and Configurations

With variable frequency control, you can control the speed of the tumble. Customers can achieve a simple polish at low speed or even aggressive deburring and radiusing at higher speeds, reaching up to 150 RPM.

This machine can be fully customized with a touchscreen control panel, parts separator, drain pan, infrared safety curtain, and more. See the accessories table for more information on customizable options.

HZ-160 Features and Benefits

1

Full-size production

This model provides more than five times the capacity and efficiency of MFI’s compact centrifugal barrel tumblers like the HZ-40.

,

Deep barrels

At almost 12” in diameter, these barrels are deeper than the smaller HZ-Series models and ideal for wider parts. Each barrel can be divided into 16 individual chambers.

*

Built-in cover lift

Easily lift off your barrel lids, eliminating the need for excessive force when loading and unloading the machine.

Reduce manual labor

Manual labor and handwork can be very time-consuming, expensive, demanding, and dangerous. Our HZ-Series Centrifugal Barrel Finishing Machines take the handwork out of finishing.

Short cycle times

Clean up metal, acrylic, rubber, and other materials in just minutes, rather than spending hours or days doing it by hand or using other finishing methods.

y

Quieter operation

Compared to vibratory equipment, this series runs much quieter. They can be installed in places you wouldn’t want vibratory machines installed, such as where other machines’ tolerances may be affected.

Achieve a mirror-like finish

Nearly impossible to achieve by hand, our polishing machines can achieve a mirror-like finish on a variety of parts.

Save time and money

Due to the friction and force created by these machines, they run much more efficiently, using less media, water, and compound compared to other finishing methods.

Safe and easy operation

The integral hood switch and two-button jog requirement makes this series extremely safe to operate. The hood is securely locked during cycles. A built-in cover lift, timers, and controls makes running the machine simple.

HZ-160 Barrels

The HZ-160 Centrifugal Barrel Finisher features four 20.625” wide by 11.8’’ diameter barrels. They are over 3 inches longer and almost 2 inches deeper than the HZ-120, making it ideal for wide parts. The barrels come with removable lids that are secured with cam locks for safe and efficient operation. The machine is equipped with an air-driven cover lift that is controlled by a toggle switch located on the control panel. This feature allows for easy removal of the barrel covers.

Customizable Barrel Dividers

With 15 divider slots, it is possible to create 16 individual chambers within each barrel if utilizing our optional barrel dividers. This allows operators to separate parts into several different chambers within each barrel. This is a critical feature when part-on-part impingement needs to be avoided.
