BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing cutting debris wrapped around a cutting tool.

0002

[Prior Art] When machining a workpiece into various shapes, conventional machining centers alternately cut the workpiece using a plurality of cutting tools corresponding to the various shapes. When using it again depending on the processing order,
If the next cutting process is performed with the cutting chips from the previous machining still wrapped around the tool, the wrapped cutting chips may cause unexpected damage to the workpiece, or the tool may be damaged by the tool being driven together with the cutting chips. There are disadvantages in that unnecessary stress is applied to the tool, which makes the tool more likely to be damaged and shortens the life of the tool.

[0003] As a means to solve the above-mentioned drawbacks, the tool is rotated in a reverse direction different from that during machining every time the machining process of the workpiece is completed, and the cutting debris generated during machining that is wrapped around the tool is shaken out. I had dropped it. However, if the cutting waste is shaken off every time the machining process is completed, there is a problem in that the workpiece is placed in a standby state and time is lost before starting the next machining.

SUMMARY OF THE INVENTION The present invention was devised in view of the above-mentioned problems, and provides a method for removing cutting debris wrapped around a tool.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention comprises a cutting tool with cutting waste wrapped around it and a brush that can be brought relatively close to the tool in the direction of the tool, and the brush is the same as the tool that faces the tool. The cutting waste is transferred to the brush while relatively rotating either one of the brushes in a reverse rotational relationship different from that during machining, and the brush and the tool are relatively moved away from each other. It is characterized by its tip facing downward.

[0006]

[Operation] According to the above structure, the cutting debris is transferred to the brush while rotating one of the brushes, which brings the cutting tool closer to the cutting tool around which the cutting debris is wrapped, relative to the brush so as to have a reverse rotational relationship different from that during machining. The cutting waste can be removed by moving the brush and the tool away from each other, and by directing the tip of the brush downward.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a schematic configuration of a machining center, which includes a storage section 2 that stores a plurality of cutting tools 1 having shapes necessary for cutting a workpiece, and the tools 1 are mounted on a spindle 3. An automatic exchange function is built in, and a table 4 for fixing the workpiece is installed in a position opposite to the spindle 3, and the necessary tool 1 is selected from the storage section 2 according to the machining procedure, and the tool 1 is selected for each machining process. A numerical control device 5 and an electromagnetic control panel equipped with programs for automatic exchange, changes in the workpiece, changes in cutting conditions, changes in the tool 1, etc. are provided, A safety guard 6 is provided to prevent cutting debris 7 and chips generated from the workpiece from scattering outside the machining center, and to prevent contact with the workpiece and tool 1 during machining.

In detail, as shown in a conceptual diagram of a method for removing cutting debris from a tool shown in FIG. 2, a brush 8 facing the tool 1 with cutting debris 7 wrapped around it is arranged as shown in FIG. 2(a), Either the opposing tool 1 or the brush 8 is rotated in a reverse direction different from that during machining, and the tool 1 or the brush 8 is rotated and brought closer together as shown in FIG. The cutting waste 7 that was wrapped during machining is transferred to the brush 8 by rotating one of them in the opposite direction, and the tool 1 and the brush 8 are connected as shown in FIG.
As shown in c), the brush 8 is moved relatively far away, and the tip of the brush 8 to which the cutting waste 7 has been transferred is directed downward to cause the cutting waste 7 to fall.

As another embodiment of the present invention, the brush 8 to which the cutting debris 7 has been transferred may be rotated to cause the cutting debris 7 to fall;
In addition, even in the above method, if all of the cutting debris 7 does not fall from the brush 8 and some remains are still attached, a removal brush that can be rotatably brought close to the brush 8 is provided, and a removal brush is installed at the base of the brush 8. The remaining cutting debris 7 is dropped by rotating the removal brush toward the tip. Alternatively, a scraping brush is disposed close to the brush 8, and the remaining cutting debris 7 is scraped off by moving the scraping brush from the root of the brush 8 toward the tip.

[0010] With the above configuration, since the cutting debris wrapped around the tool can be removed by the mechanically operated brush, the workpiece can be machined into various shapes using the tool from which the cutting debris has been removed. , it is possible to cut smoothly, without damaging the workpiece, prolonging the tool life, and cutting the machining contents determined at the initial stage.

[0011]

[Effects of the Invention] As mentioned above, the cutting tool is one in which cutting debris is wrapped around the workpiece while cutting the workpiece, and the cutting tool with the cutting debris still wrapped around the cutting tool cuts the workpiece. When cutting, the cutting debris causes unexpected damage to the workpiece, but since the cutting debris wrapped around the cutting tool can be removed by a brush that brings it relatively close, the cutting debris can cause unexpected damage to the workpiece. If the cutting process is continued with the cutting tool with the cutting debris wrapped around the object, unnecessary stress will be applied to the cutting tool that is driven with the cutting debris, and the cutting tool may be damaged. It is possible to cut the machining contents determined at the initial stage without shortening the life of the tool.
