摘要： An object is to provide a machine-tool spindle cooling method and a machine tool capable of suppressing thermal deformation of a spindle while achieving energy saving. To achieve it, a machine-tool spindle cooling method is provided in which bearings (13) and a spindle rotation motor (14) that generate heat with rotation of a spindle (12) are cooled by causing a spindle cooling device (18) to supply and circulate cooled cooling oil inside a housing (11) rotatably supporting the spindle (12), the method comprising deactuating the spindle cooling device (18) to thereby stop supplying the cooling oil in a case where the number of revolutions of the spindle (12) is less than or equal to a predetermined number of revolutions and the temperatures of the bearings (13) and the spindle rotation motor (14) detected by temperature sensors (15, 16) are less than or equal to a predetermined temperature.

摘要： An inter-substrate material layer is formed between a first substrate and a second substrate to generate a bonding strength. A plurality of metal elements are present in the inter-substrate material layer. An interface element existence ratio of the plurality of metal elements is 0.07 or above. A device can be obtained in which substrates difficult to bond (for example, SiO2 substrates) are bonded at room-temperature to have practical bonding strength.
