FUCHS RENOFORM ZSB 120 JBM is a high-performance, mineral oil-based fine blanking and heavy-duty precision punching lubricant formulated with specialized extreme-pressure (EP) and boundary additives. Featuring a higher kinematic viscosity grade (approx. $134\text{ mm}^2/\text{s}$ at $40\text{ }^\circ\text{C}$), it creates an ultra-durable separation film designed to withstand extreme compressive forces, preventing tool wear, die pick-up, and galling during severe metal-forming operations. It is highly suitable for processing all types of steel—including high-alloyed, galvanized, and stainless steels—ensuring exceptionally clean cut surfaces, straight burnished edges, and long tool die life. The fluid features a high flash point ($> 160\text{ }^\circ\text{C}$) for enhanced operational safety under demanding, high-load press cycles.
