Jun 01, 2010 · The Mini Mill is now the shop''s principal electrode milling machine. High speed capacity comes from the airdriven spindle—or, in the case of this machine, various spindles. Multiple airdriven spindles wait in the tool carousel, ready with various tools.


The change in air pressure over time has important forecasting impliions. As pressure lowers over time, especially if it is rapid, that is an indiion that a low pressure system or front is approaching. This lowering pressure indies an increasing likeliness of precipitation. If the air pressure rises significantly or stays well above
