금속을 이용한 다양한 대량 생산 공장 | 한국의 금속제품 대량생산 과정 

Unbelievable!!!! I remember as an apprentice, I worked for 1 year in a heavy engineering works. A friend of mine ( a bit older, mind) worked there, and I saw him working on a Colchester Student lathe, fed with hex bar, turning out 100's of small set screws every single day!!!! Changed days indeed!!!!!

Wow, the production process is so modern
