Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to hard and brittle materials such as cemented carbide, Sendust and Alnico, and highly viscous materials such as Inconel, Heist steel, stainless steel and aluminum, and
The present invention relates to a processing method for performing processing such as cutting and grinding on a difficult-to-cut material such as a combination composite material.

[0002]

2. Description of the Related Art Conventionally, when processing such a difficult-to-cut material, for example, a processing apparatus as shown in FIG. 2 has been used.

That is, in FIG. 2, the processing apparatus 1 is provided with a processing table 2 on which a workpiece can be placed, and is arranged above the processing table 2 and is rotationally driven as shown by an arrow A. C which is lowered as shown by arrow B during processing
It is composed of the BN wheel 3 and, at the time of processing,
After the workpiece 4 made of a difficult-to-cut material is placed on the processing table 2 first, the CBN wheel 3 is driven to rotate in the direction of arrow A, and is lowered in the direction of arrow B, whereby the workpiece is processed. A predetermined portion of the object 4 is cut or ground.

[0004]

However, in the processing apparatus 1 having such a structure, the cutting waste of the workpiece 4 enters the portion of the processing blade 3a on the outer peripheral portion of the CBN wheel 3 during processing. As a result, the CBN wheel 3 will be clogged and the cutting performance of the CBN wheel 3 will be significantly deteriorated.
Or using a WA stick, use the CBN wheel 3
Therefore, there is a problem that the working efficiency in the working work is not so good and the working distortion occurs.

In view of the above points, the present invention makes it possible to improve the working efficiency without interrupting the working operation due to the dressing of the CBN wheel during the working with the CBN wheel. It is intended to provide a method for processing a material.

[0006]

According to the present invention, the above object is to rotate and drive a CBN wheel disposed above a work table with respect to a work piece placed on the work table. In the method of processing a difficult-to-cut material in which the workpiece is cut, ground or the like by lowering the workpiece toward the processing table, the workpiece is cut on the processing table with respect to the rotation direction of the CBN wheel. A dressing stick is arranged adjacent to the back of the workpiece, and the CBN is used during processing.
This is achieved by a method of processing a difficult-to-cut material, characterized in that the wheel engages with both the work piece and the dressing stick to perform processing such as cutting and grinding.

[0007]

According to the above construction, during processing, the CBN wheel engages with both the workpiece and the dressing stick to perform processing such as cutting and grinding. The machining blade on the outer peripheral portion of the CBM wheel first engages with the workpiece to perform cutting, grinding, etc. of the workpiece, and then, in accordance with the rotation direction thereof, moves to the rear of the workpiece. It will engage the dressing stick that is located so that it can be dressed immediately after processing the work piece.

Therefore, since the working blade of the CBN wheel is always dressed by the dressing stick immediately after working, the working blade of the CBN wheel is not clogged by the working. Since the cutting performance is always kept the best, it is not necessary to interrupt the machining work for dressing the CBN wheel, and thus, the machining work efficiency can be improved and the machining strain can be reduced. Become.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in the drawings. FIG. 1 shows an embodiment of a processing apparatus for carrying out the processing method according to the present invention.

The processing apparatus 10 is provided with a processing table 11 on which a workpiece can be placed, and is arranged above the processing table 11 so as to be rotationally driven as indicated by an arrow A, and at the time of processing, an arrow mark. As shown by B, the CBN wheel 12 is made to descend, and during processing, the workpiece 13 made of a difficult-to-cut material is first placed at the processing position on the processing table 11. Along with the rotation direction of the CBN wheel 12, a dressing stick 14 such as a WA stick is placed behind the workpiece 13.

The processing apparatus 10 according to the present invention is configured as described above, and when processing the work piece 13, as described above, the work piece 13 and the dressing stick are placed on the work table 11. After placing 14, the CBN wheel 12 is driven to rotate in the direction of arrow A and lowered in the direction of arrow B to cut or grind a predetermined portion of the workpiece 13.

At this time, in the CBN wheel 12, the processing blade 12a at the outer peripheral portion of the CBN wheel 12 is engaged with the work piece 13 in advance, and the work piece 13 is cut and ground. According to the rotation direction, the dressing stick 14 located behind the workpiece 13 is engaged. As a result, the processing blade 12a of the CBN wheel 12 can be dressed by the dressing stick 14 immediately after the processing of the workpiece 13.

Therefore, the processing blade 12a of the CBN wheel
Is always dressed by the dressing stick 14 immediately after processing during processing, so that it will not be clogged. Thus, there is no need to interrupt the work for dressing the CBN wheel 12 during the work, the work efficiency can be improved, and the work distortion can be reduced.

[0014]

As described above, according to the present invention, C
When machining with a BN wheel, the dressing of the CBN wheel does not interrupt the machining work so that the working efficiency can be improved, and the machining method for extremely difficult-to-cut materials with reduced machining distortion. Will be provided.
