In the drawing, reference numeral 1 denotes a base such as a bed, which supports and guides a table 2 on a top surface thereof through a sliding guide portion 3 so as to move in a horizontal direction, that is, in a longitudinal direction perpendicular to the plane of FIG. A feed screw portion 4 for driving and moving the table 2 in the horizontal direction with respect to the base 1 is provided between the upper surface of the base 1 and the table 2. Thus, on the upper surface of the base 1, the sliding guide portion 3 and the feed screw portion 4 can be held so as to extend in a state of being immersed in lubricating oil over substantially the entire surface thereof. Groove oil tank 5,5
Is formed, and the lubricating oil in the groove-shaped oil tank portions 5, 5 is transferred between the lubricating oil storage tank 11, the pump 13, the filter 12, and the storage tank 11 by a lubricating oil circulating supply device including a pipe. It is configured to be circulated. In addition, 1a, 1a is a base 1 for preventing the lubricating oil in the grooved oil tank portions 5, 5 from overflowing.
It is an overflow prevention weir provided on the outer periphery of the upper surface. As shown in FIG. 2, the feed screw portion 4 is screwed with a nut 4 'fixed to the lower surface of the table 2, and both ends are supported by bearings 4a and 4b, and one end of the feed screw is connected to the bed via a coupling 4c. 1 Connected to the motor 4d fixed on the upper surface. Further, for the lubricating oil liquid, a temperature sensor 6 and a position (oil level) sensor (level sensor) 7 are provided in the groove-shaped oil tank portion 5, and the temperature of the lubricating oil becomes higher or lower than a set temperature. If you make a change like
The controller 8 receives the signal from the temperature sensor 6 to extract the signal, and the temperature controller 9 cools or heats the lubricating oil supplied to the grooved oil tanks 5,5. Further, the position sensor 7 issues an alarm for the consumption of the lubricating oil such that the lubricating oil in the groove-shaped oil tanks 5, 5 drops below a predetermined level, activates the pump 13, operates the filter 12, the temperature controller 9, and the like. To supply the lubricating oil liquid. When the position sensor 7 detects an overflow of the oil level, it gives a detection signal to the controller 8, loosens the valve 10 by the control signal of the controller 8, and discharges the lubricating oil liquid 5 to the lubricating oil storage tank 11. Spontaneously reflux as much as it overflows. Further, when replacing the lubricating oil, the valve 10 can be manually opened and closed to perform the replacement.
