New deburring and finishing technology from Extrude Hone The new CoolPulse 200T innovative electrolytic deburring and polishing machine from Extrude Hone performs various key funtions for an all in one finishing process.
The pulsed electrolytic technology, CoolPulse* 200T deburring and polishing
machine from Extrude Hone, a subsidiary of Kennametal Inc., performs five
key functions: deburrs, polishes, stress relieves, cleans and provides
passivation (removes free-iron particles) - all in one finishing process.
A "cool" and environmentally friendly process CoolPulse is ideally suited for small to medium-sized workpieces that may be inherently delicate or intricate by design. Typical fields of applications are medical components such as scissors, scalpels, stents or orthopedic implants and sophisticated parts for aerospace, semi-conductor, and the automobile industry. CoolPulse ECM technology from Extrude Hone is virtually applicable for nearly all conventional metals and metal alloys.
In the CoolPulse ECM process, the workpiece to be machined is immersed in an electrolyte solution, the "liquid tool," as a low voltage is applied. The proprietary electrolyte used in the process is a chilled, non-fuming, odorless, near-neutral solution, rendering it very safe for handling, and is considered environmentally friendly. The solution possesses high electrical resistance, enabling high selectivity and high discrimination for the removal of burrs and peaks on workpiece surfaces. As a rule, and unlike other electrolytic processes, outside surfaces of the workpiece can be processed in the absence of complicated conformal cathode tooling. The liquid bath used in the CoolPulse process is able to treat many different types of metals with only minor changes to the electrical settings on the machine. Brilliant results In addition, "short process times are a prominent feature."
says Jim Koroskenyi, Product Manager at Extrude Hone: "The CoolPulse
process is significantly faster than typical electropolishing. Average
cycle times range from 15 seconds up to 3 minutes; smaller components
typically take 10 to 15 seconds." Got a Cool Job in Machining?- Our Dedicated Portal Helps U- $ave See all the Press Releases from Kennametal sites. Read a recent article about -
