Oak Ridge National Laboratory 

K. O. Lee Instrumented
Creep Feed Grinder


The K. O. Lee Vigor CNC creep feed grinder is available for user research projects at the High Temperature Materials Laboratory. This precision grinder is fully instrumented to facilitate data collection and analysis. Process variables that can be easily measured include table and wheel speeds, grinding forces, spindle vibration amplitude and frequency, power consumption, coolant pressure and temperature.  The machine features a horizontally mounted, high-speed, variable-speed spindle, fully enclosed hood, large work table with electromagnetic chuck, and a NUM Model 1040 controller with conversational programming capabilities.
