Kennametal Precision Surface Solutions offers its Extrude Hone EVO next-generation electrochemical machining (ECM) platform featuring generator technology delivering between 3 and 100 kW of power, depending on machine configuration. According to the company, the machine performs ECM without stray machining attack, which means higher surface finish quality and improved component performance.
The ECM process works on the principle of anodic metal dissolution. A DC current is applied to the part, while a tool cathode determines the shape of the material removal without contacting the part. An electrolyte solution transfers the charge between the gap, and the resulting electron current releases metal ions from the workpiece. Using the electrolyte, the removed material is flushed out of the gap as a hydroxide and captured by a filter system. The ECM process is capable of targeted material removal in precise locations and is said to cause no mechanical or thermal stress. It is suitable for contouring, radiusing, polishing, deburring and flow tuning applications
The Extrude Hone Evo ECM machine is available in single-, dual- or multi-cell configurations thanks to the system’s modular design and construction. According to the company, it is easy to configure and integrate into production lines. For customers looking for specific machining operations, the machine integrates with an interface for dynamic ECM. It also enables online monitoring and control of parameters.
