The new simple simulating tests have always been desired strongly in order to evaluate the lubricity of lubricant in cold sheet rolling, because of complexity and cost of experimentation with actual rolling processes. The purpose of the study is to develop a new simulation testing machine. In the new type of simulating test, it is necessary to deform, the workpiece material plastically which is different from the simulating test such as Timken test. The contact behavior between rolls and workpiece is undoubtedly closer to that in rolling practice. The roll can be rotated at a high relative speed and moreover, the normal force and tangential force can be measured individually. The new simulation testing machine developed is sufficient for these necessary conditions. The apparatus is very simple and the cost for experiments is cheap. This machine is effective for evaluation of the lubricity of lubricant in cold sheet rolling.
