HARPERIZING/
CENTRIFUGAL FINISHING

WHAT IS HARPERIZING?

Harperizing, also known as centrifugal finishing, is a high-energy finishing process that deburrs and polishes parts in a shorter period compared to conventional tumbling and vibratory finishing. It uses centrifugal force to apply abrasives to parts, resulting in superior surface finishes.

    • Faster processing time compared to conventional tumbling

    • Superior surface finishes with minimal material loss

    • Ability to reach recessed areas and intricate geometries

    • High consistency in part quality

    • Cost-effective for high-volume production

    • Produces smoother surfaces and aggressive edge radiusing

    • Excellent for both metal and plastic parts

    1. Preparation: Parts are placed into a centrifugal finishing machine.

    2. Abrasive Application: Abrasives are applied to the parts.

    3. Centrifugal Action: High-energy centrifugal force is activated, polishing and deburring the parts.

    4. Finishing: The parts are removed and cleaned for final inspection.

  • Harperizing/Centrifugal Finishing is used across a variety of industries, including:

    • Aerospace: For turbine blades, aerospace components requiring precise finishes

    • Medical: Ideal for medical instruments, implants, and devices demanding a high level of cleanliness

    • Automotive: For engine components, suspension parts, and cosmetic exterior pieces

    • Firearms: To smooth and polish firearm components

    • Electronics: Small, intricate parts requiring surface refinement

    Common parts include:

    • Components requiring high cosmetic finishes

    • Parts requiring low-micro finishes for precision

    • Aggressive edge radiusing

    • Material removal for both metal and plastic

    • Cleaning recessed areas for better surface quality

    Due to the size limitations of Harperizing/Centrifugal Finishing machines, parts generally range from .010” to 2” in size.

  • This unique finishing process deburrs and polishes parts in a much shorter period of time compared to conventional tumbling and vibratory finishing. Centrifugal finishing is a great alternative to tumbling and vibratory finishing because of the G forces produced, which allows access to areas where conventional methods cannot reach. Often referred to as “high-energy tumbling” or harperizers, these rapid finishing machines excel in polishing, deburring, and deflashing both metal parts and various types of plastics. The process results in high-quality finishes in shorter cycle times, making it efficient and cost-effective for manufacturers.ption
