Description of the Related Art There is a machine tool for cutting a work by relatively moving the tool and the work while supplying a cutting fluid, particularly a high-pressure cutting fluid, to a processing portion between the tool and the work. In processing using such a machine tool using a high-pressure cutting fluid (as well as a coolant), it is necessary to cover the entire processing area with a fully-closed splash guard to prevent the cutting liquid from scattering outside the processing area. However, the fully-closed splash guard comes with difficulty in carrying in the work.

(A) As shown in (b), the covers 1 and 3 that cover both side surfaces of the processing area and the cover 5 that covers the upper surface are the base 7 of the machine tool.
And a cover 9 that covers the front surface of the machining area moves up and down with respect to the machine tool, and the front surface is opened as shown in (a) and closed as shown in (b). However, in this case, the work setup work on the machine is difficult to perform, and must be performed outside the machine, and a pallet exchange mechanism is required for the outside setup.

取り作業が行いにくい。Further, as shown in FIGS. 5 (a) and 5 (b), covers 1 and 3 which cover both side surfaces of the processing area are fixed to a base 7 of the machine tool, and are movable so as to cover the front and upper surfaces of the processing area. There is a type in which a cover 9 constituted by covers 11, 13, and 15 moves in a horizontal direction with respect to the machine tool to open and close the front and top surfaces thereof. Note that the cover 11 is fixed to the side cover 1, and the movable cover 13 is configured to move with the well-known structure by moving the movable cover 15 left and right. In this case, scale 19 on table 17
B-axis rotation mechanism is required. Otherwise, the loading and unloading of the work must be performed as shown by the arrows, and it is difficult to set up the work.

からのワークの取外時に、ワークとスプラッシュガード
との干渉問題が発生し、その作業性が非常に悪い。In the type of the splash guard as described above, the entire machining area, particularly the side face thereof, cannot be opened, so that the work is mounted on the machine and the work is removed from the machine. Occasionally, a problem of interference between the work and the splash guard occurs, and the workability is very poor.

のコストアップに繋がる。For example, in a horizontal machining center, a work is generally mounted on the surface of the scale 19 provided on the table 17 facing the main shaft. However, if the splash guard can open only the front surface of the processing area. ,
Workpiece with work mounted in advance by pallet changer
It is necessary to load and unload the pallet on which the pallet 19 is loaded and unloaded from the machine, and indirectly attach the workpiece to the machine and remove the workpiece from the machine. It leads to up.

要があり、同様に、工作機械のコストアップに繋がる。If the splash guard is of the type as shown in FIG. 5, the front and top surfaces of the processing area can be opened, but the side surfaces cannot be opened. Work must be attached and detached, and the workability is very poor. For this purpose, the table 17 is rotated around a vertical axis by a rotation mechanism,
It is necessary to mount the work on the machine and remove the work from the machine, with the work mounting surface of the scale 19 facing the front once, which also leads to an increase in the cost of the machine tool.

Since the cutting fluid is not actively supplied to the back surface, a temperature difference occurs between the front and back surfaces of the scale 19 due to the cooling effect of the cutting fluid, and a processing error due to thermal deformation of the scale 19 may occur.
