첫댓글 턴테이블 베어링에 5mm구멍이 8개씩있으나 등분이 아닙니다. 등분으로 믿었다간 낭패를 봅니다. 새로이 8등분하여 탭을 내었는데 생쇼를 했습니다. 지그를 만들어 내는 수밖에 없더군요. 380mm Sub tool 가공용으로 스토퍼자리도 미리 만들어 두었습니다.
가공의뢰할 때 재료선택을 잘해야 합니다. CNC나 조각기 작업하는데 최악의 재료는 MC 플라스틱입니다. 가공 찌꺼기가 엔드밀에 녹아 들러붙으니 수시로 구동을 멈추고 떼어내어야 하므로 아주 싫어합니다. 그래서 가공물에 비해 가공임이 높읍니다. PC(폴리카보네이트)는 알콜을 공급하면서 가공하면 들러붙지는 않으나 썩 반기지 않고, 베이크라이트는 알콜을 공급하면 베이크라이트에 알콜이 흡수되어 가공성이 떨어지고 엔드밀에 열이 나 결과적으로 엔드밀을 버리게 되니 바늘값(엔드밀 값)을 더 받아요. ABS가 가장 가공성이 좋아요. 여기서 가공성이라는 것은 가공한 면의 조도를 말합니다. 수지계통으로는 아세탈이 최적입니다.
옛날에는 아세탈값이 비쌌으나, 요즈음은 아크릴값 수준입니다. 투명하기로는 PC가 최고인데 가격은 베이크라이트의 93% 수준입니다. 가공하는데 시간과 재료값이 높아서 그렇지 알루미늄이 가장 깨끗하게 나옵니다. 가공하기 전에 가공집의 취향을 물어보고 하세요. 나중에 얼굴 붉히지 말고.....
드디어 시작하시는군요.
