Abstract
A broken tool detection mechanism applied in a CNC machine includes a base support, a first conductive elastic sheet securely mounted on the base support, and a second conductive elastic sheet. The second conductive elastic sheet is mounted on the base support, at least partially located over the first conductive elastic sheet, and spaced apart from the second conductive elastic sheet by a predetermined distance. The second conductive elastic sheet is pushed towards the first conductive elastic sheet so that the first conductive elastic sheet and the second conductive elastic sheet make electrical contact.
