  • Patent number: 6670310
    Abstract: A high performance lubricant to extend the life of tooling to punch holes and shear metals especially thick steel members. The lubricant, due to its modified viscosity, remains on the tool during the process allowing it to provide the necessary coating to reduce the friction developed. Most punching processes mount the tool vertical and the work is held below the tool. Lubricant is applied to the tool prior to punching. A problem with lubricants presently used is the viscosity is so low the lubricant runs off the tool prior to the punching process rendering the lubricant ineffective. The thixotropic index of the lubricant is controlled by addition of fumed silica to provide the proper viscosity to keep the lubricant on the tool and then during the punching process the viscosity is reduced sufficiently by the shear energy applied between the tool and work to allow the lubricant to flow in the shear area thereby providing maximum lubrication between the tool and the work.
