Methods and apparatus for detecting machine tool window airtightness includes an airtight state detector, having a sensor detecting the pressure in a space of the window, and a judging section for determining appropriateness of the airtight state of the space based on a pressure value from the pressure sensor and outputting a judgment result. Pressure in the window space, which initially may be pressurized or pressure-reduced, is detected intermittently by the pressure sensor, and the judging section determines appropriateness of the airtight state of the window on the basis of a variation state of the detected pressure.
A method of detecting, on a machine tool having a cover body with a window, an airtight state of the window, the window comprising two transparent or translucent window plates which are airtightly joined together with a predetermined distance between them, the method comprising:
An airtight state detecting apparatus which detects, on a machine tool having a cover body with a window, an airtight state of the window, the window comprising two transparent or translucent window plates which are airtightly joined together with a predetermined distance between them, the airtight state detecting apparatus comprising:
