Description of the Related Art Usually, an aluminum substrate for a magnetic disk is turned on its inner and outer diameters and front and back surfaces with a lathe by using a dedicated or general-purpose precision lathe. FIG. 3 shows an example thereof. In FIG. 3, 1 is a vacuum chuck, 2 is a spindle, 3 is a tool rest, 4 is a parallel chuck, 5 is a rotary actuator, and 6 is an inversion stand. The turning chips generated by such turning are sucked from the cutting dust suction tray provided below the vacuum chuck 1 of the aluminum substrate to the dust suction port and then to the dust suction device. 1 and 2 show the outline of a conventional dust suction device, and from this figure, a dust suction port 10 'is formed relatively large. For example, in the example of FIGS. 1 and 2, the dust suction port has a diameter of about 500.
is a cm 2, and the distance from the vacuum chuck 1 to dust inlet 10 'is spaced about 200 mm.

じる。However, unlike a so-called free-cutting alloy, an aluminum alloy used as a substrate for a magnetic disk tends to have a relatively long length without breaking the chips. Therefore, a dust collecting device used in a conventional lathe is used. If used as is, cutting chips from turning could become entangled with the cutting tool and scratch the product. In order to prevent such a defect, it is necessary to increase the dust suction wind speed to suck the chips. For that purpose, it is indispensable to use a large dust collector that can generate a large amount of air, which causes a problem of the installation area and a problem of the price of the machine.

とする。An object of the present invention is to provide a dust suction method capable of efficiently sucking turning chips generated by turning with a small amount of air and making it possible to suck dust of a large number of lathe machines with the same dust collector.

ある。According to the present invention, when an aluminum substrate for a magnetic disk is turned by a lathe and the cutting dust is sucked from the dust suction port below the vacuum chuck, the dust suction port sucks dust from the tip of the cutting tool. The distance to the mouth is 100 mm or less, the opening area is 200 cm 2 or less, and the dust suction speed is 2 m /
By setting the time to be at least seconds, the above problem is solved.

ック１に近接して設けられている。1 and 2 show the outline of a dust suction device according to an embodiment of the present invention together with a conventional device. In these figures, the dust suction port 10 has an opening diameter of 500 cm of the conventional device.
It is formed to be smaller than about 2 , for example, 200 cm 2 or less, and is provided close to the vacuum chuck 1 so that the distance (a) from the tip of the cutting tool to the tip of the dust suction opening is 100 mm or less.

用いる場合、従来より風速が大きく取れる。As described above, in the present invention, since the diameter of the dust suction port is small and the distance from the vacuum chuck 1 to the dust suction port 10 is short, that is, the dust suction port is provided close to the vacuum chuck 1, the size is relatively small. Effective dust absorption is also possible by using a dust collector. Further, when the same dust collector is used, the wind speed can be made higher than in the past.

Since dust can be absorbed, there is an effect that equipment cost and factory space can be saved.
