FIG. 4 is a schematic cross-sectional view of a side cutter cutting waste collection device taken along line YY shown in FIG.

As shown in FIGS. 2 (a) and 2 (b), when performing groove cutting according to the up-cut method, the side cutter 2 equipped with the chip collecting device 10 for the side cutter is attached.
Is installed on the workpiece 15, and the workpiece 15 is moved in the direction opposite to the rotation direction, that is, the direction of arrow 20, with respect to the side cutter 2 rotating in the direction of arrow 30 about the rotary shaft 7. As a result, the cutting blade 16 mounted on the outer peripheral edge of the side cutter 2 cuts the workpiece 15 so as to scrape it up from the lower portion of the groove.

Simultaneously with the start of cutting, as shown by an arrow in FIG. 2 (b), air having a flow rate of about 3 to 15 kg / cm ² is supplied from the fluid supply pipes 5, 5'through the fluid supply holes 3, 3'to the cover 1 Introduce inside. The air introduced into the cover 1 is made to flow in the direction of the cutting waste discharge path 4 along the rotation direction 30 of the side cutter 2, as shown by the arrow in FIG. Due to this, the cutting waste 18 scraped off in the processing part
Is washed away with the air toward the front of the processing part. Further, the cutting debris 18 is guided by the cutting debris discharge path 4 and efficiently discharged to the outside of the cover 1. Cutting waste 1 discharged
8 can be efficiently collected by further utilizing suction or the like.

When the groove cutting is performed according to the up-cut method, the cover auxiliary plate 11 attached to one end of the back surface 1b of the cover 1 is moved as shown in FIGS. 2 (a) and 4 (a). The lowest position is set so as to cover the gap between the groove bottom surface 19 and the end of the back surface portion 1b of the cover 1. As a result, the cutting waste 18 is pushed out in the direction of the cutting waste discharge path 4, so that the loss of the air flowing into the cover 1 can be suppressed as much as possible, and the airtightness inside the cover 1 can be enhanced.

On the other hand, as shown in FIGS. 3 (a) and 3 (b), when the groove cutting is performed by the down-cut method,
The side cutter 2 to which the chip collecting device 10 for the side cutter is attached is installed on the workpiece 15, and with respect to the side cutter 2 rotating in the direction of the arrow 30 about the rotating shaft 7,
The workpiece 15 is moved in the same direction as the rotation direction, that is, in the direction of arrow 21. As a result, the cutting blade 16 mounted on the outer peripheral edge of the side cutter 2 cuts below the surface of the workpiece 15 to perform cutting.

Simultaneously with the start of cutting, as shown by an arrow in FIG. 3 (b), air having a flow rate of about 3 to 15 kg / cm ² is supplied from the fluid supply pipes 5, 5'through the fluid supply holes 3, 3'to the cover 1 Introduce inside. The air introduced into the cover 1 flows in the direction of the cutting discharge path 4 along the rotation direction 30 of the side cutter 2, as shown by the arrow in FIG. Due to this, the cutting waste 18 scraped off in the processing portion is
It is washed away with the air behind the processing part. Further, the cutting waste 18 is guided by the cutting waste discharge path 4 and the groove portion created by cutting, and is efficiently discharged to the outside of the cover 1. The discharged cutting chips 18 can be efficiently collected by further utilizing suction or the like.

When the groove cutting is performed according to the down-cut method, the cover auxiliary plate 11 attached to one end of the back surface portion 1b of the cover 1 is, as shown in FIGS. 3 (a) and 4 (b). , Is set at the highest position so as not to contact the surface of the workpiece 15.

As described above, the side cutter cutting waste collecting apparatus 10 of the present embodiment can adjust the fixing position of the cover auxiliary plate 11 in the cover 1 up and down as needed to perform up-cutting or down-cutting appropriately. Can be applied. Therefore, as compared with the conventional side cutter in which the entire cover is removed and reset every time the cutting method is switched, the labor of the work can be significantly simplified.

Further, the side cutter cutting waste collecting apparatus 10 of this embodiment can be attached to various commercially available cutter tools. For example, when the side cutter cutting waste collection device 10 of the present embodiment is set to a cutter tool having a plurality of chip pockets provided on the outer peripheral edge thereof adjacent to the cutting blade, the cutting wastes are rotated into the chip pockets. Even if the side cutter passes by the side of the cutting waste discharge path 4 in the state where it remains or the cutting waste adheres to the cutting edge,
Next, be sure to connect the fluid supply hole 3, until the cutting edge contacts the cutting point.
Pass near 3 '. Therefore, the remaining cutting chips are all washed by the fluid in the vicinity of the fluid supply holes 3 and 3'within the chip pocket or from the surface of the cutting edge and are not brought to the cutting point. As described above, when the cutting waste collecting device 10 for a side cutter of the present embodiment is used, the cutting edge of the side cutter is cleaned by the fluid between one cutting and the next cutting. It hardly happens that it cuts into the cutting edge of.

In the above embodiment, only the example in which the cover 1 of the side cutter cutting waste collecting apparatus 10 is provided with the pair of fluid supply holes has been described, but as shown in FIG. A pair of auxiliary fluid supply holes 22 and an auxiliary fluid supply pipe 23 connected to the auxiliary fluid supply hole 22 may be further provided at predetermined positions above the surface portions 1a and 1a ′. In this case, since the cutting edge of the side cutter 2 is exposed to the fluid several times before reaching the cutting point, the discharge effect of the cutting waste is further improved.

The fluid introduced into the cover 1 is 80
It may be high temperature air heated to about 200 to 200 ° C. If high temperature air is used, the temperature difference cycle of the cutting edge can be moderated, wear of the cutting edge can be suppressed, and the tool life can be extended.

Furthermore, in the cutting waste collecting device for a side cutter of this embodiment, only the use of air as a fluid is illustrated, but cutting oil may be used instead of air. If cutting oil is used as the fluid, the effect of discharging cutting chips can be further enhanced. This is because the cutting oil acts as a lubricating oil when the cutting debris is swept away in the direction of the cutting debris discharge path 4, so that the cutting debris is between the cutting debris and the chip pocket surface provided on the outer peripheral edge of the side cutter. This is because friction or the like does not occur and the guide is smoothly guided to the outside.

[0045]

According to the cutting waste collecting device for a side cutter according to the present invention, at the time of grooving by the side cutter, the cutting waste is removed by the flow of the fluid introduced into the cover portion or the outer peripheral edge of the side cutter. It can be washed away from the section and efficiently discharged to the outside of the cover.

Further, in the cutting waste collecting device for a side cutter according to the present invention, the state of the end portion of the cover facing the cutting waste discharging path with the shaft of the side cutter interposed therebetween is removed without removing and resetting the entire cover. By just adjusting it, it can be applied to both up-cut and down-cut cutting methods in a timely manner.
