Cryogenic DeburringĮven when machined PEEK parts aren’t complex, manual deburring is still time-consuming. Nitrofreeze® cryogenic deburring doesn’t require the ability to look inside and reach tight spaces, and it’s more precise than hand tools sine it uses media sized from 0.015” to 0.060” to solve application-specific challenges.
When burrs are deep inside a machined PEEK part, workers who use handheld tools may not be able to see inside the bore very easily, and this can affect quality.
Little to no dust or residue remains, and there aren’t any physical or mechanical changes to part properties.Ĭompared to manual deburring, cryogenic deburring is better for hard-to-reach part geometries such as blind holes and cross-drilled holes. The machined PEEK parts are then impacted with a non-abrasive polycarbonate media that removes only the surface imperfections. During this cryogenic process, PEEK parts are cooled to very low temperatures so that the parts become brittle. Nitrofreeze® cryogenic deburring is a safe, clean process that’s been used in applications such as the removal of burrs from PEEK medical implants. Manual deburring is time-consuming, inefficient, and inconsistent, but cryogenic deburring is fast, accurate, and repeatable. After plastic machining is complete, manufacturers need to remove burrs that can interfere with assembly or impede performance. For example, PEEK rods need to be annealed to remove stresses and machined with silicone carbide tools. Although PEEK supports CNC machining at faster speeds and feeds, there are still some best practices to follow before, during, and after machining. Machined industrial-grade PEEK is used in wheels, rollers, bearings, bushings, and aerospace parts. Machined medical-grade PEEK is used in implants, dental healing caps, and spinal fusion, trauma fraction, and orthopedic devices. Polyetheretherketone (PEEK) comes in medical and industrial grades, both of which support CNC machining operations such as milling and drilling. PEEK is a high-performance plastic that can be machined into tight-tolerance parts with excellent wear and abrasion resistance.
