Abstract:
A machine tool maintenance system comprising:a plurality of machine tools each including a plurality of driver mechanisms and a controller for controlling operations of the driver mechanisms; and a management unit connected to the plurality of machine tools; wherein the controller of each of the machine tools comprises a life expectancy determining section for determining degrees of wear of the respective driver mechanisms on the basis of operating conditions of the respective driver mechanisms; wherein the management unit comprises a data storage section for receiving data indicative of the wear degrees of the respective driver mechanisms determined by the life expectancy determining section of each of the machine tools and storing the data of the wear degrees, and an output section for outputting information on the wear degrees stored in the data storage section, wherein the life expectancy determining section estimates end-of-life times at which service lives of the respective driver mechanisms end, on the basis of the determined wear degrees.
