Nedan ett klipp från en tråd på Yahoo Mach forumet, en liten uppmaning i all välmening att inte lämna maskiner obevakade!
There are a lot of us that trust mach and our machines enough to leave them onovernight or leave them running while we go get a cup of tea.yesterday i was machining a job in oak. luckily for the first time so i didntleave it!i use diamond (pcd) spiral cutters for all my cutout workthese have the tips added to the steel shank of the cutter.(in the same way a carbide tool can have the tips brazed on)anyway, on the last job the tool had pinged a corner lump off some oak and ididnt realise had lost a tip. effectively this turned the tool into a highfriction grinding bar instead of a cutter!the tool entered the job and tried its best to burn its way through. in secondsthe workshop was full of smoke! the oak was smouldering bright red as were thechippings around it, being fanned by the spindle cooling air. im pretty surethere would have been some well kindled flames if i wasnt there.so the moral...... Dont leave it un attended.i caught the act on video. you can see how quick this can happen. shame i didnt carry on filming i was too busy snuffing out the smoulderings if i had my extractor on all the hot stuff would have been in my dust bag
