DMTS - O is a contact-type 3D tool setter that can detect and automatically compensate for various broken tools, tool diameters, and tool wear. The product uses infrared signal transmission. DMTS - O consists of a high - precision switch, a hard polyhedral contact head with high hardness and high wear resistance, and a signal triggering mechanism. The contact head is used to contact the tool, and through the flexible support rod installed below it, the force is transmitted to the high - precision switch; the on - off signals sent by the switch are transmitted through the triggering mechanism. After the receiver receives the signals, they are transmitted to the numerical control system to identify, calculate, compensate, store, etc. the tool length and diameter.
