Abstract

PURPOSE: To provide a marking device made capable of detecting a broken tool, by means of supervising a contact detecting signal, in the method of keeping to feed a contact signal all the time while being made the contact between tool and work.
CONSTITUTION: In the machine tool, for processing a work by back-and-forth moving a work W installed to a table 12 sliding on a bed 11 with respect to a tool T mounted to the spindle of a main shaft head 10, a contact detecting coil 13 is installed to the point end face of the main shaft head 10 and both ends of the coil 13 are connected to AC power source 14 through a current detecting resistor R1. A contact made between the tool T and the work W causes an induced current to flow through an induced current path 15, with a voltage increasing across both ends of the resistor R1. This voltage signal is inputted as a detection signal with the contact detection operated.
