HZ-12 Centrifugal Barrel Finisher
HZ-12 High-Energy Centrifugal
Barrel Finishing Machine
The HZ-12 is Mass Finishing’s most compact industrial high-energy finishing machine. The HZ-12 works well in small places like dental and medical device labs or in cell productions. Despite its smaller stature, it still packs the same high-end finishing punch of its bigger counterparts.
Machine Type: Compact
Max Part Size: 8″ L x 4.5″ D
Barrel Dimensions: 8.375″ L x 5″ D
Popular Industries: Medical, Dental, Jewelry, and Swiss Machined Parts
HZ-12 Basic Operation
The HZ-12 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-12 is isotropic, meaning parts are polished uniformly and evenly in all directions, something that cannot be achieved by hand finishing.
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-12 Features and Benefits
Small footprint
As our most compact machine, the HZ-12 can fit in some of the smallest locations.
Easy to maneuver
The large caster wheels on the HZ-12 base make it easy to move around the production facility.
Quieter operation
At 70 to 80 dB, our belt driven barrel tumblers are much quieter than other finishing methods such as vibratory tumbling.
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.
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.
Safe and easy operation
The integral hood switch and two-button jog requirement makes these machines extremely safe to operate. The hood is securely locked during cycles.
HZ-12 Barrels
The HZ-12 Centrifugal Barrel Finisher comes standard with four removable barrels. The entire barrel is removed from the machine to load and unload media and parts. With each barrel requiring a few handfuls of media to function, these machines are great for micro-sized precision parts. This closed system doesn’t require a constant flow of water and compound, so wastewater is minimized.
By purchasing a second set of four barrels, the operator can run one set of barrels while loading and preparing another. This can dramatically reduce machine downtime.
HZ-12 Tool-Less Lockdown Bars
The HZ-12 Tool-Less Lockdown Bars are an upgrade from our original lockdown bars and are now a standard feature on all HZ-12 machines. For those still utilizing MFI’s original lockdown bars, we’re pleased to offer these upgraded bars for $265.
The Tool-Less Lockdown Bars are designed to fit seamlessly with your current machine, requiring no modifications.
The new lockdown bar design offers:
Tool-less operation
There is no longer a need for tools such as socket wrenches or drills during barrel loading, greatly simplifying the process.
Less wear and tear & reduced replacement parts
With no bolts and mechanics delivering consistent pressure, the new design eliminates the risks of over and under-tightening the barrels. This in turn reduces the wear and tear on equipment, decreasing maintenance costs and prolonging machine lifespan.
Faster and safer operation
With a more simplified installation process, less time is spent on setup, allowing you to maximize efficiency and productivity. They also reduce the risks associated with improper barrel tightening.
