Modern drilling and milling heads in CNC machines feature hydraulic/pneumatic chucks for quick, safe and automatic tool changes. Due to the fast tool changes, drilling and milling heads can process easily an item with several tools, in only one operation. However, this requires a smooth operation of clamping systems such as drilling, lathe and power chucks, even at maximum speeds and high tensioning forces. LUBCON high pressure resistant greases reduce press-fit and centrifugal forces as well as torque and provide a uniquely high load carrying capacity for an error-free tool change and precise, safe and efficient operation. The high-performance greases protect machine tool disc springs and chucks against friction, wear as well as tribo-corrosion and enable thus a longer service-life.
