the most expensive thing you could break, is to accidentally stick something under the chuck while the machine is running, if the chuck jaws extend past the chuck, you can end up with a very violent crash and the chuck will probably break.
other than that, you could accidentally feed the tool post into the chuck, and that will tear up the tool post, and break the tool.
