HZ-85 Centrifugal Barrel Finisher
HZ-85 High-Energy Centrifugal Barrel
Finishing Machine
The HZ-85 is a high-efficiency industrial finishing machine that shares similarities with MFI’s HZ-60 model but offers a larger capacity. With almost 8” larger barrels than the HZ-60, it is an ideal machine for those that require more space to process their parts. Equipped with a cover lift, this model makes lifting the lid off your barrels a breeze.
Machine Type: High Efficiency
Max Part Size: 33″ L x 5.5″ D
Barrel Dimensions: 33.5″ L x 5.8″ D
Popular Industries: Knives, Firearms & Munitions, Aerospace
HZ-85 Basic Operation
The HZ-85 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-85 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 225 RPM.
This machine can be fully customized with a touchscreen control panel, parts separator, drain pan, infrared safety curtain, and more. See the Specs & Resources table for more information on customizable options.
How It Works
Centrifugal barrel finishing, also known as centrifugal barrel tumbling, operates on the “Ferris Wheel” principle with a one-to-one ratio of barrel rotation to turret rotation. The process involves loading four barrels with a mixture of parts, water, compound, and media, which are filled to around 50-80% capacity. As the machine rotates, the barrels spin around the turret and on their own axis, creating a sliding force inside the barrel.
HZ-85 Features and Benefits
Full-size production
This model provides more than double the capacity and efficiency of MFI’s compact centrifugal barrel tumblers like the HZ-12 and HZ-40.
Wide barrels
At 33.5” wide, these barrels can be divided into 15 individual chambers inside each of the 4 barrels. This helps to avoid part-on-part impingement and damage from parts hitting each other.
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
In a matter of minutes, centrifugal barrel finishers can clean up metal, acrylic, rubber, and other materials in what could take hours or even days by hand.
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 make this series extremely safe to operate. The hood is securely locked during cycles.
HZ-85 Barrels
The HZ-85 Centrifugal Barrel Finisher features four 33.5” wide by 5.8’’ diameter barrels. These 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 14 divider slots, it is possible to create 15 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.
