본 발명은 연삭 숫돌의 드레싱 검사 방법 및 이에 적합한 지그에 관한 것으로서, 보다 상세하게는 연삭 숫돌의 드레싱 작업 정밀도를 향상시킬 수 있는 연삭 숫돌의 드레싱 검사 방법 및 이에 적합한 지그에 관한 것이다.The present invention relates to a dressing inspection method for a grinding wheel and a jig suitable therefor, and more particularly, to a dressing inspection method for a grinding wheel that can improve the dressing work precision of a grinding wheel and a jig suitable therefor.

일반적으로, 연삭 작업은 공작물의 표면을 연마하는 작업으로서 원판형의 연삭 숫돌을 사용하여 공작물을 소정의 형상으로 연마할 수 있을 뿐만 아니라 절단할 수 있다.In general, the grinding operation is a grinding operation of the surface of the workpiece, and can be used to cut the workpiece into a predetermined shape as well as to cut it using a disc grinding wheel.

상기한, 연삭 숫돌은 산화 알루미늄계와 탄화 규소계로 대별되는 연삭 입자와 이 연삭 입자를 결합시켜 주는 결합제로 구성되어 있고 전기한 결합제는 무기질계와 유기질계로 나뉘어 진다.The grinding wheel is composed of grinding particles which are roughly divided into aluminum oxide-based and silicon carbide-based, and a binder for bonding the grinding particles, and the aforementioned binder is divided into inorganic and organic.

연삭기에 장착되어 있는 연삭 숫돌을 회전시켜 통상의 척에 삽착되어 있는 공작물을 연삭하면 연삭 숫돌에 형성되어 있는 다수의 연삭 입자가 연마되면서 공작물을 연삭한다.When the grinding wheel mounted on the grinding machine is rotated to grind the workpiece inserted in the normal chuck, the workpiece is ground while a plurality of grinding particles formed on the grinding wheel are polished.

마모된 연삭 입자는 연삭 숫돌의 표면에서 박리되어 떨어지고 다시 도출된 새로운 연삭 입자에 의해 공작물이 연삭된다.The worn grinding particles are peeled off from the surface of the grinding wheel and the workpiece is ground by the new grinding particles again drawn out.

상기한 바와 같이 연삭 입자의 마모와 더불어 마모된 연삭 입자가 박리되기 위해서는 연삭 입자를 결합시키는 결합제와 연삭 입자의 결합도를 측정하여 이상적으로 조정해야 한다.As described above, in order for the worn abrasive particles to peel together with the wear of the abrasive particles, the binding degree of the binder and the abrasive particles to which the abrasive particles are bound should be measured and ideally adjusted.

결합도가 너무 낮으면 연삭 입자가 마모되기 전에 박리되어 불 경제적이고 결합도가 너무 높으면 마모된 연삭 입자가 박리되지 않아 연삭성이 저하된다.If the bonding degree is too low, the abrasive particles are peeled off before they are abraded, and if the bonding degree is too high, the worn grinding particles are not peeled off and the grinding property is degraded.

여기서, 연삭 숫돌의 결합도는 연삭 깊이, 연삭 속도, 공작물의 속도등 많은 변수가 포함되어야 하기 때문에 정확하게 결합도를 정해서 공작하기는 불가능하다.In this case, the grinding degree of the grinding wheel must include a number of variables such as the grinding depth, the grinding speed, the speed of the workpiece, it is impossible to accurately determine the degree of engagement.

그래서, 연삭 숫돌의 연삭 입자가 마모되어 연삭성이 저하됨과 아울러 연삭 입자의 박리가 행해지지 않으면 통상의 드레서를 사용하여 연삭 숫돌의 표면을 가공하는 드레싱을 한다.Therefore, if the grinding particles of the grinding wheel are abraded, the grinding property is degraded, and the grinding particles are not peeled off, dressing is performed to process the surface of the grinding wheel using a normal dresser.

그러나, 종래에는 상기한 통상의 드레서로 연삭 숫돌을 드레싱한 후 다시 공작물의 형상에 맞는 형태로 연삭 숫돌이 정확히 드레싱되어 있는지의 여부를 시력을 통한 외관 검사에 의존함으로서 드레싱되어 있는 연삭 숫돌의 치수가 부정확할 뿐만 아니라 이로 인해 연삭되는 공작물의 형상이 정밀하게 연삭되지 않는 문제점이 있었다.However, in the related art, after grinding the grinding wheel with the conventional dresser as described above, the size of the grinding wheel being dressed by relying on visual inspection through the visual inspection whether the grinding wheel is dressing correctly in a form suitable for the shape of the workpiece is determined. In addition to the inaccuracy, there was a problem that the shape of the workpiece to be ground is not precisely ground.

따라서, 본 발명의 목적은 드레싱되어 있는 연삭 숫돌의 치수를 정확하게 제어할 수 있는 연삭 숫돌의 드레싱 검사 방법을 제공함에 있다.Accordingly, it is an object of the present invention to provide a dressing inspection method for a grinding wheel that can accurately control the dimensions of the grinding wheel being dressed.

본 발명의 다른 목적은 상기한 드레싱 검사 방법에 적합한 연삭 숫돌의 드레싱 검사 지그를 제공함에 있다.Another object of the present invention is to provide a dressing inspection jig of a grinding wheel suitable for the dressing inspection method described above.

상기한 목적을 실현하기 위하여 본 발명은 삽탈 자재할 수 있는 판상형의 흑연판과 이를 고정시킬 수 있는 베이스로 구성됨을 특징으로 한다.In order to realize the above object, the present invention is characterized by consisting of a plate-like graphite plate that can be inserted and removed and a base to which it can be fixed.

상기한 바와 같은 판상형의 흑연판을 통상의 소켓 보울트를 이용하여 베이스에 고정시키고 드레싱이 완료된 연삭 숫돌로 이를 연삭하여 연삭된 흑연판을 통상의 프로젝터(Projecter)나 측정 기기를 통해 흑연판에 형성된 연삭홈의 치수를 측정함과 아울러 정확한 치수로 보정한다.The plate-shaped graphite plate as described above is fixed to the base by using a conventional socket bolt, and grinding it with a grinding wheel that has completed dressing, and the ground graphite plate is ground on a graphite plate through a conventional projector or measuring device. Measure the groove dimensions and correct them to the correct dimensions.

이하, 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도면은 본 발명에 따른 연삭 숫돌의 드레싱 검사 지그의 일 실시예를 도시한 사시도로서, 베이스(1)의 상단 일측에 흑연판 삽입홈(2)이 형성되어 있고 베이스(1)의 상면에는 흑연판(3)을 고정시키기 위한 소켓 보울트(4)가 삽입되어 있으며 전기한 흑연판(3)이 흑연판 삽입홈(2)에 삽입되어 있다.The figure is a perspective view showing an embodiment of the dressing inspection jig of the grinding wheel according to the invention, the graphite plate insertion groove 2 is formed on one side of the upper end of the base 1 and the graphite plate on the upper surface of the base 1 (3) The socket bolt 4 for fixing is inserted, and the aforementioned graphite plate 3 is inserted into the graphite plate insertion groove 2.

통상의 연삭기에 연결되어 있는 회전축(5)에 드레싱이 완료된 연삭 숫돌(6)을 장착한다.The grinding grindstone 6 with which dressing is completed is attached to the rotating shaft 5 connected to the normal grinding machine.

그리고, 도시하지 않은 연삭기의 공작대 상면에 흑연판 삽입홈(2)이 형성되어 있는 베이스(1)를 안착시키고 여기에 흑연판(3)을 삽입함과 아울러 베이스(1)의 상면에 형성되어 있는 소켓 보울트(4)를 조여 흑연판(3)을 고정시킨다.And the base 1 in which the graphite plate insertion groove 2 is formed is seated in the upper surface of the working table of the grinding machine which is not shown in figure, The graphite plate 3 is inserted in this, and it is formed in the upper surface of the base 1 The socket bolt 4 is tightened to fix the graphite plate 3.

다음, 연삭기에 연결되어 있는 회전축(5)을 회전시킴으로서 연삭 숫돌(6)을 회전시키고 흑연판(3)이 장착되어 있는 베이스(1)를 전진시켜 회전하는 연삭 숫돌(6)에 밀착시킨다.Next, the grinding wheel 6 is rotated by rotating the rotary shaft 5 connected to the grinding machine, and the base 1 on which the graphite plate 3 is mounted is advanced to closely adhere to the rotating grinding wheel 6.

연삭 숫돌(6)에 밀착된 흑연판(3)은 연삭되어 연삭 숫돌(6)과 동일한 형태의 연삭홈(7)을 형성한다.The graphite plate 3 in close contact with the grinding wheel 6 is ground to form a grinding groove 7 having the same shape as the grinding wheel 6.

여기서, 흑연판(3)은 통상적인 흑연재의 판을 사용하였는 바 이는 흑연판(3)의 입자가 조밀할 뿐만 아니라 균일하고 그 점도 및 경도가 적당하여 연삭 숫돌(6)의 연삭 입자를 마모시키지 않으면서 드레싱된 연삭 숫돌(6)의 형태가 흑연판(3)의 연삭홈(7)을 통하여 정확하게 도출되기 때문이다.Here, the graphite plate 3 used a plate of a conventional graphite material, which is not only dense particles of the graphite plate 3 but also uniform and its viscosity and hardness are suitable to wear the grinding particles of the grinding wheel 6. This is because the shape of the grinding grindstone 6 that is dressed without being made is accurately drawn through the grinding groove 7 of the graphite plate 3.

상기한 바와 같은 연삭홈(7)이 형성된 흑연판(3)을 베이스(1)에서 분리시켜 통상의 측정 장치인 프로젝터(Projecter)로 측정하여 마모된 연삭홈(7)의 치수를 정확하게 측정한다.The graphite plate 3 on which the grinding grooves 7 are formed as described above is separated from the base 1 and measured by a projector, which is a conventional measuring device, to accurately measure the size of the worn grinding grooves 7.

상기한 방법을 반복함으로서 소정의 연삭 숫돌(6) 치수를 정확하게 드레싱한다.By repeating the above method, the predetermined grinding wheel 6 dimensions are accurately dressed.

특히, 상술한 본 발명의 실시예에서는 흑연판(3)을 사용하였는 바 이에 한정하는 것은 아니고 예컨대 백묵이나 석회석등 그 입자가 조밀하여 연삭 숫돌(6)의 형태를 정확하게 나타낼 뿐만 아니라 연삭 숫돌(6)의 형상을 마모시키지 않는 재질을 사용하는 것에 그 특징이 있다.Particularly, in the above-described embodiment of the present invention, the graphite plate 3 is used, but the present invention is not limited thereto. For example, chalk or limestone may be densified to accurately represent the shape of the grinding wheel 6 and the grinding wheel 6. This feature is characterized by the use of a material that does not wear the shape of).

이상과 같이 본 발명은 베이스에 고정된 흑연판을 드레싱이 완료된 연삭 숫돌로 연삭함과 아울러 이와 같이 형성된 흑연판의 연삭홈을 통상의 프로젝터와 같은 측정 장치로 그 치수를 측정하여 드레싱된 연삭 숫돌의 치수를 소정의 형태로 정확하게 드레싱할 수 있다.As described above, the present invention grinds the graphite plate fixed to the base with the grinding wheel which has been finished dressing, and measures the dimensions of the grinding groove of the graphite plate thus formed by measuring the dimensions with a measuring device such as a conventional projector. The dimensions can be accurately dressed in the desired shape.
