We had a bit of a disaster last night. Because of poorly trained, inattentive machine operators on 3rd shift, we had a pretty bad fire on one of our CNC routers. The improperly set the depth, then started the machine, turned and walked away, then evacuated the building when the fire alarm went off, and never even looked at or stopped the machine. It ran on and burned for more than 20 min until the FD showed up.
It burned off all the dust-shroud brushes, the dust collector hose, and the vacuum hose to the table. Not sure if the wiring for the air cylinder sensors for the dust-shroud doors will be ok. (They look a little melted) Or if the air cylinders will still work. The lines to them will have to be replaced The a 10kw HSK63f router spindle is wrecked (doesn't spin free), we'll send it out to see if it's rebuildable. But the biggest problem is that the 5ft by 10ft 1.5inch thick cast aluminum table cracked! It cracked about 2ft in from the front left corner and runs about half way across the table in the 5ft direction. The table is supported from below by 10 linear guide blocks on two rails. The crack runs across between the 1st and 2nd set of blocks, about 4inches from the 2nd block. Is there any hope of repairing the table? Are we going to have to replace the whole table? Could the crack be welded, or is that a bad idea? My main fear is that warpage issues will cause the linear guides to bind. (The table surface can always be re-milled flat.) The crack isn't gaping or misaligned, and the table doesn't "look" warped now that It's cool. Todd Zuercher P.
