Another vote for misting or brush on cutting oil/lubricant. One of the worst jobs at work was getting tapped to clean out the machine coolant tanks. They were always nasty smelling and full of swarf that was small enough to slip through the drain systems into the sump. Since I don't use a coolant system there is very little in the chip pan other than the swarf itself.
For large piles of swarf I use a homemade chip hook something like this:
For the smaller stuff I use a small piece of 16 gauge 316 stainless and scrape it over the edge of the chip tray into a 5 gallon bucket. The larger lathe has plenty of room under the bed to reach to the back of the pan. The smaller one has a pan that will slide out for cleaning. I use the same methods for both machines.
Here's a picture of each of the machines with the scrapers in the chip pan. Note the stainless scrapers are near the tailstock end of the machines. The 5 gallon bucket is on the floor under the larger machine. I usually wait until I have at least a couple buckets full before I take them over to the recycle center. Originally I filled a 30 gallon barrel then hauled it over. That was fine until they started went to a larger steel dumpster. It was a real PITA to attempt to lift the barrel 6' up to tip it over the edge.
