PURPOSE: A device for measuring the strength of a table of a machine tool is provided to precisely process a workpiece by using a capacitive sensor to obtain reliable data. CONSTITUTION: A device for measuring the strength of a table of a machine tool comprises a jig unit(100), a plurality of measuring units(200), a measuring server, and an oil supply unit(400). The plurality of measuring units are installed on a bed(20) of a machine tool and supported at a predetermined interval from a table(10) by the jig unit. The measuring unit measures the strength of the table, which changes according to the weight of a mass for strength measurement, from the variation in the height difference of the table floating according to the amount of supplied oil. The measuring server collects electric signals measured by the measuring units, converts the signals into data, records and stores the data, and measures the strength of the table by analyzing the data. The oil supply unit supplies oil to the table according to the weight of the mass for strength measurement.
