Rust Preventatives
Rust inhibitors are important for EDM (Electrical Discharge Machining) because they prevent the formation of rust and corrosion on both the workpiece and machine components during and after the machining process. EDM often uses water-based dielectric fluids, which can promote rusting on ferrous metals due to the presence of water and oxygen. Without rust inhibitors, these conditions can quickly lead to oxidation, resulting in:
-
Surface damage to the machined parts, reducing their quality and potentially causing dimensional inaccuracies.
-
Corrosion of machine components such as fixtures, workholders, and internal parts, leading to increased maintenance needs and potential machine downtime.
-
Difficulties in cleaning and maintenance, as rust and corrosion can cause debris and contaminants to adhere more strongly to surfaces, complicating post-process cleaning.
-
Reduced lifespan and reliability of both the machine and produced parts, increasing operational costs and the risk of failure.
Rust inhibitors work by forming a protective barrier on metal surfaces, preventing water and oxygen from initiating the rusting process. This barrier is essential for maintaining the precision, surface finish, and integrity of both the workpiece and the EDM machine itself, especially during long machining cycles or when parts are left in the tank for extended periods.
In summary, using rust inhibitors in EDM machining is critical for protecting equipment and workpieces, ensuring high-quality results, and minimizing downtime and maintenance costs
