There is known a method in which the grindstone 1 and the work 2 are rotated by press contacting with each other. According to this method, the work 2 is cut into the grindstone 1 by the pressure of the cylinder 3 and is continuously pressed and processed until it is stopped by the stopper 4. FIG. 5 shows the relationship between the depth of cut and time during processing.

形したまま加工されてしまうことがあり、高精度な仕上
り面を得ることは容易ではなかった。However, in the above method, since the work 2 is constantly pressed by the grindstone 1 to be machined, when the grindstone 1 is cut into the work 2 and the depth of the work 2 is reduced, If there is a projecting part on the work surface of the work 2, the pressure may be concentrated on that part, and the work surface such as chipping or pricking may partly drop off,
In particular, in the case of a press material, the above-mentioned problem often occurs because the peripheral edge of the work is raised or there is a thick portion during die cutting. Further, in the case of a work that has a thin wall and is easily deformed, the grindstone may be deformed at the time of pressure contact and may be machined while being deformed, so that it is not easy to obtain a highly accurate finished surface.

を解決する。In order to solve the above-mentioned problems, the present invention solves the problems by automatically making a cutting motion of a grindstone into a work by a servomotor.

がなくなる。According to the present invention, as compared with the continuous cutting motion by the pressurizing means such as the cylinder and the spring, the intermittent cutting motion causes the grindstone to be extremely cut into the work and a partial excessive force. Will not be concentrated. Further, even when the work is pressed against the grindstone and deformed, the work is not always pressed, so that only the portion contacting the grindstone is gradually shaved by the restoring force of the work itself and is not deformed and processed.

【実施例】以下本発明を実施例の図に於いて説明する。The present invention will be described below with reference to the drawings of the embodiments.

る。First Embodiment In FIG. 1, a work 2 is held on a work shaft 5 by an appropriate means such as a chuck, the work shaft 5 is fixed to an arm 7, and the arm 7 is fixed by a ball screw 8 rotated by a servomotor 9. It can move up and down on the linear guide 10. The servo motor 9 is instructed by the sequencer 12 via the positioning unit 11 to work 2
Can be moved to an arbitrary position and stopped.

もよい。The work 2 is intermittently cut as shown in the graph of FIG. 2 by a preprogrammed sequencer 12 and a servomotor 9 which receives the command. For example, after cutting 0.01 mm per second, stop for 1 second, and then cut 0.01 mm per second again, and then
The cut is performed by repeating the operation of stopping for a second. The amount of cut, time and operation pattern are changed by the program of the sequencer 12 and set according to the workpiece to be processed. It should be noted that the setting from now on may be made by a digital switch, a timer, a volume, etc., instead of being made by a program.

場合と同様に仕上り面が良好となる。By making the cuts as described above, the work 2 does not extremely cut into the grindstone 1, and is gradually scraped away from the high portion of the surface to be processed of the work 2, so that the work 2 such as chips or pits is generated. There will be no partial chipping. Further, since the work 2 having a small thickness and easily deformed is not continuously pressed, it is gradually scraped from the portion contacting the grindstone without deforming,
Even if it is deformed, while the cutting is stopped, the portion of the workpiece 2 having a high pressure is scraped by the restoring force of the workpiece 2 to be restored to the original shape and processed with high accuracy. In this method, since the cutting is stopped after the cutting, the finished surface becomes good as in the case where the processed surface is leveled.

ワーク２の仕上がりを均一にすることができる。Second Embodiment Further, the cutting method is not preset by a program or the like as described above, but the work shaft 5 is slidable on the arm 7 as shown in FIG. The pressurizing means applies pressure to the grindstone 1 to make a cut, and the work shaft 5 moves downward as the work surface of the work 2 is processed, and the backing plate 15 attached to the work shaft 5 causes the arm 7 to move. Even if the limit switch 16 senses that it is not in contact with the workpiece, the arm 7 is moved downward again to start the cutting, resulting in intermittent cutting. Good. The limit switch 16 is not limited to this and may be a pressure sensor, a photoelectric sensor, or the like as long as it detects that the work 2 is no longer processed. By doing so, even if the sharpness of the grindstone is deteriorated, the finish of the work 2 can be made uniform.

る。As described above, according to the present invention, even if the work has a shape such as a chip or a chip which is easily chipped or is easily deformed, the work is processed with high accuracy and the finished surface is also good.
