From 1976 to 1981 my brother and I worked in a PCB manufacturer every Saturday morning and during college holidays. We used to programme and run these Excellon multi-spindle drilling and routing machines.
The drill rotational speed was 120,000RPM for 0.8mm to 1.0mm size holes. This was space age stuff in the day. https://www.youtube.com/watch?v=lavSgjoaf7s The drill bits were cooled by the air that sucked up the swarf. Tiny blockage and the drills would melt. The hole positions were digitised and transferred to the machine control computers using punched paper tape like this. https://www.youtube.com/watch?v=P6P_oiZWi_o Last edited by MSS; 14th June 2019 at 14:43.. |

In the 60s/70s i worked in the machine shop at a local factory HY-MAC producing heavy duty excavators.We were the 1st factory in this area to use CNC machines. They are easy to use,just press a button. The person who programs the machine was the one with a degree. I will always remember there was one component that we made had a 25min cycle,load into machine and go for a cup of tea.
