Uniquely designed polymer resins, permeated with abrasive materials, allow the controlled surfaces to become abraded and/or polished. These materials may be customized for specific results with various grit types, sizes, viscosity and flow rates that allow an efficient material removal and/or polishing specific to desired results.
A temperature-controlled cooling jacket encapsulates the pressurized work area for consistent and repeatable flow-control objectives. The key variables to control in the Abrasive Flow Finishing (AFF) process are media type, operating pressure and surface speed of the media flow.
In most cases, a simple fixture is needed to successfully deploy the abrasive media in the location desired and at the correct, consistent and repeatable surface speed.
Fixtures can be made from inexpensive, structural-grade nylon that provides a more than adequate strength-to-weight ratio and can be easily machined to customized configurations.
Media viscosity and flow rates are controlled by pressure and temperature settings engineered for maximum efficiency and effective results.
