도 1은 종래의 투포원 연사기를 나타내는 사시도1 is a perspective view showing a conventional two-point gun twister
도 2는 본 발명에 따른 플라즈마 용사시스템을 나타내는 블록도Figure 2 is a block diagram showing a plasma spraying system according to the present invention
이와 같은 목적을 달성하기 위한 본 발명의 실시 예를 하기에서 첨부된 도면을 참조하여 살펴본다.An embodiment of the present invention for achieving the above object will be described with reference to the accompanying drawings.
본 발명에 따른 연사기용 스핀들 디스크 제조방법은 알루미늄을 사용하여 CNC(Computer Numerical Control)가공하여 스핀들 디스크를 제조한 후, 플라즈마용사법을 이용하여 스핀들 디스크의 외주에 세라믹코팅(Al2O3-TiO2(60:40wt%)을 한다.Spindle disk manufacturing method according to the present invention according to the present invention, after manufacturing a spindle disk by CNC (Computer Numerical Control) processing using aluminum, using a plasma spray method on the outer circumference of the spindle disk ceramic coating (Al2O3-TiO2 (60: 40wt %).
한편, 상기한 본 발명에서 플라즈마 용사시스템은 공지된 것으로, 그 실시 예를 하기에서 첨부된 도 2를 참조하여 살펴본다.On the other hand, the plasma spraying system in the present invention described above is known, looks at the embodiment with reference to the accompanying Figure 2 below.
우선, 플라즈마용사란 비전이형아크(NONTRANSFERED ARC)에 의해 여러 가지 가스(수소, 질소, 알곤 등)가 이온화되어 생성되는 고속(평균610cm/sec) ,고온(약16700℃)의 플라즈마 흐름(PLASMA STREAM)을 이용하는 코팅방법으로서 플라즈마 용사시스템 내에서 일정하게 공급되는 분말 코팅제가 용융 또는 반용융(MOLTEN OR SEMIMOLTEN)상태에서 초음속의 속도로 소재에 충돌 밀착되어 섬세한 조직의 코팅피막을 형성하는 것으로, 그 실시 예를 하기에서 살펴본다.First, plasma spray is a high-speed (average 610 cm / sec) and high-temperature (about 16700 ° C) plasma flow generated by ionizing various gases (hydrogen, nitrogen, argon, etc.) by NONTRANSFERED ARC. Is a coating method that is supplied in a plasma spray system in a molten or semi-melt state in a molten or semi-melt state to collide with the material at a supersonic speed to form a delicate coating film. An example is given below.
가스공급기(Gas supply)로부터 공급되어 제어장치(Control Equipment)에 의하여 토출량이 제어된 아르곤가스 및 수소가스와, 전원공급부(Power)로부터 인가되어 상기 제어장치(Control Equipment)에 의하여 전압과 전류가 제어된 출력전압과, 압축공기(Compressed Air)와, 칠러냉각기(Water Chiller)에 의하여 냉각된 냉각수 및, 파우더 공급기(Powder Feeder)로부터 공급된 세라믹분말이 플라즈마건(Plasma Gun)으로 공급되어 고온, 고속으로 세라믹분말이 용융 혹은 반용융되어 스핀들 디스크 상에 충돌되면서 세라믹 코팅층을 형성하게 된다.Argon gas and hydrogen gas supplied from a gas supply and controlled by a control device, and discharged by a control device, and are supplied from a power supply to control voltage and current by the control device. Output voltage, compressed air, cooling water cooled by chiller chiller, and ceramic powder supplied from powder feeder are supplied to plasma gun to provide high temperature and high speed. The ceramic powder is melted or semi-melted to impinge on the spindle disk to form a ceramic coating layer.
한편, 상기한 바와 같은 플라즈마 용사법에서 플라즈마 건에 공급되는 전압과 전류의 세기에 따라 플라즈마 화염의 온도 및 온도분포가 변화하므로, 본 발명에서는 플라즈마 건으로 공급되는 출력전원을 바람직하게 30-40 kW, 500A로 제어되며, 알곤가스와 수소의 혼합비에 따라 플라즈마 화염의 온도 및 분위기가 변화되므로 본 발명에서는 아르곤가스(Ar)는 80 SCHF로 제어되고, 수소가스는 10-25 SCHF로 제어된다. 그리고, 플라즈마건과 피용사체(스핀들 디스크)간의 거리 플라즈마 화염이 스핀들 디스크에 도달할 때의 플라즈마 화염온도와 용융입자의 비산속도를 지배하므로, 본 발명에서는 용사거리를 60-90mm로한다.On the other hand, since the temperature and temperature distribution of the plasma flame changes in accordance with the intensity of the voltage and current supplied to the plasma gun in the plasma spray method as described above, in the present invention preferably output power supplied to the plasma gun 30-40 kW, 500A Since the temperature and the atmosphere of the plasma flame is changed according to the mixing ratio of the argon gas and hydrogen, in the present invention, argon gas (Ar) is controlled to 80 SCHF, hydrogen gas is controlled to 10-25 SCHF. The distance between the plasma gun and the target object (spindle disk) governs the plasma flame temperature and the scattering speed of the molten particles when the plasma flame reaches the spindle disk, so that the spraying distance is 60-90 mm in the present invention.
이와 같은 조건하에서 제조된 스핀들 디스크는 알루미늄 소재를 이용하여 CNC 가공을 행하기 때문에 진원도 및 동심도가 2/100가 되어 스핀들 디스크 품질향상을 꽤할 수 있고 세라믹 코팅을 행하면 일정기간 사용 후 세라믹 코팅을 제거한 다음 다시 세라믹 코팅을 사용할 수 있기 때문에 원가절감을 할 수 있다.Since the spindle disk manufactured under such conditions is CNC processed using aluminum material, the roundness and concentricity will be 2/100 to improve the spindle disk quality.If the ceramic coating is applied, after removing the ceramic coating after a certain period of time, Since the ceramic coating can be used again, the cost can be reduced.
한편, 상기에서 세라믹코팅 제거법은 공지된 것으로 이를 간략하게 살펴보면 그릿(세라믹볼) 블라스팅기계를 이용하여 세라믹코팅층을 제거하는데 압축공기가 노즐을 통하여 분사될 때 그릿이 혼입되어 세라믹코팅층을 타격하여 세라믹코팅층을 제거하는 것이다.On the other hand, the method of removing the ceramic coating is well known. Briefly, the ceramic coating layer is removed by using a grit (ceramic ball) blasting machine. To remove it.
본 발명에 따른 스핀들 디스크 제조방법에 의하면 알루미늄 소재를 이용하여 CNC 가공을 행하므로 진원도 및 동심도가 2/100가 되기 때문에 스핀들 디스크의 품질이 대폭 향상되는 효과가 있고, 세라믹 코팅을 행하면 일정기간 사용 후 세라믹 코팅을 제거한 다음 다시 세라믹 코팅을 사용할 수 있기 때문에 재활용을 할 수 있어서 원가절감의 효과가 있으며, 알루미늄에 세라믹 코팅을 수행하므로 종전에 비하여 경량화가 가능하게 되는 효과가 있다.According to the method for manufacturing a spindle disk according to the present invention, since the CNC machining is performed using an aluminum material, since the roundness and concentricity are 2/100, the quality of the spindle disk is greatly improved. Since the ceramic coating can be used again after removing the ceramic coating, it can be recycled, thereby reducing the cost, and since the ceramic coating is performed on aluminum, the weight can be reduced compared to the past.
