We started with practical work at the TREDU school on Wednesday, because on Monday we had a guided tour of the school premises, and on Tuesday we had two hours of English lessons where we presented Slovenia and the Slovenian school, then we went to visit the flight school in Pirkkala.
On Wednesday morning at eight o’clock we gathered in the agreed workshop where we will work for the first two weeks. Miikka’s student there first showed us a workshop. Then we talked about what we already know how to do on machines and Miikka started with a presentation of the operation of a CNC lathe. It was interesting to me at first, but then I started to get bored.
The next morning when we arrived we were supposed to be working on a program for a CNC machine on a computer, and then Mikka remembered that he could also show how this works on a CNC lathe. When he noticed that I was bored, he asked me after lunch if I wanted to work on a manual lathe. We went to the warehouse and picked a random raw material. This was a hexagon 60-millimeter-wide plain steel. First he introduced me to a lathe and then we came up with the idea that I could make a screw.
On Friday, I continued making the screw. The screw measured M45 with a standard pitch of 4.5 millimeters. When I finished making the screw it was already a snack. After lunch, I started making a nut that I couldn’t finish the same day.
The next week on Monday I made nut for the screw. The nut was made with a high tolerance, so the play between the screw and the nut was minimal and they screwed together nicely throughout the thread.
When Miikka watched me work on a classic lathe he said I had quite a smile on my face while I was working on manual lathe.
