If you’re looking for a solution for knife polishing and deburring, high-energy barrel tumblers provide a fast, environmentally friendly solution. In a matter of minutes, you can take blades from your machining or heat-treating process and put them into a centrifugal barrel tumbler and have blades and other knife components ready for assembly.
MFI processes are free of hazardous and expensive accelerated chemicals. We rely simply on the intense physical force of the machine.
How to Polish Knives
With the HZ-40 you can process 16 short (3-5 inch) blades at a time while keeping them separated in individual compartments to eliminate part-on-part damage. The HZ-60 provides 48 blade capacity while the HZ-85 gives you 60. Long blades, up to 33 inches long can fit in the tumbling chamber of the HZ-85.
Utilizing an abrasive preformed type of media, MFI has produced acceptable stonewashed finishes in as little as 5 minutes of run time. With an added step with a non-abrasive type of media, we can polish the blades in 10-20 minutes.
MFI works with custom and production knife makers around the world on solutions for creating unique matte and stonewashed finishes along with mirror polishes on blades.
Save Time and Money
In many cases, customers tumbling blades in vibratory machines are saving 8 hours or more by switching to high energy machines. That’s an entire workday! Utilizing outdated equipment or hand finishing knife blades is expensive, time consuming and in some cases dangerous for operators.
Seeing is believing, so we offer sample processing at no cost to prove that we can give you the return on investment and quality you need to make your business successful. Call or email us today to talk to a sales rep about options.
High-energy finishing is quickly becoming the industry standard for some of the world’s finest knife makers. Centrifugal Barrel Tumblers from MFI provide unmatched speed and performance even on hardened materials. In as little as five minutes of tumbling, machine lines are removed and blended evenly. Mirror finishes are also possible in one short secondary step.
Make Your Knives More Durable
At full speed, MFI Barrel Tumblers like the HZ-85 can apply upwards of 12 G’s of force on the media and parts rotating inside. This leads to greater stress relief than shot peening or any other method.
