Titanium swarf in particular burns like ****. Insurance will make companies that run a lot of titanium to have automatic fire suppression systems in their machining centres.
Your post prompted me to do a quick nosey,not that I didn't believe you. I used to do some agency labouring in an engineering place down near the Gorbals and had to clean out the swarf from cnc's...It shows you how much of an induction I (never) recieved.
Magnesium, Potassium and Sodium if my GCSE Chemistry teacher is to be believed. Mind you I spent most of my time trying to see up her skirt when she sat on the edge of her desk at the front of the class so I could be wrong. Also I'm not sure why a ship would be full of GCSE Chemistry experiments.....
I run a load of cnc’s, horrible job cleaning out the swarf. My missis would always moan like **** that I was depositing bits of metal all over the house and I couldn’t put my clothes in the machine. And good luck sitting down for a dump with swarf stuck all over the front of your clothes without having any drop off into your underpants. Lucky I have a lackey now to do all that ****e for me
Think I must have gone to the same school as you - I had never seen things like that before chemistry at secondary school. Kids normally rush to sit at the back of the class (if they turn up at all). Chemistry - full attendance - everyone on the front row. Chemistry and Biology thrown into one lesson.
.....and when she asked for volunteers to go and help with her "gardening " on a weekend she NEVER chose me. I blame it on the acne. I had forgotten all about this until your post ST. Just one comment on here can reignite a hundred memories long forgotten.
