  • Patent number: 11969803
    Abstract: According to one implementation, a drill includes the first cutting edges, the second cutting edges and a deflection reducer. The first cutting edges drill a prepared hole to a workpiece. The first cutting edges are formed in a tip side of the drill. The first point angle and each first relief angle of the first cutting edges continuously or intermittently decrease from the tip side toward a rear end side of the drill. The second cutting edges finish the prepared hole. The second cutting edges are formed at positions away in the rear end side from the first cutting edges. The second cutting edges have the second relief angles at a maximum diameter position. The deflection reducer reduces deflection of the second cutting edges by being inserted into the prepared hole. The deflection reducer is formed between the first cutting edges and the second cutting edges.

  • Publication number: 20240075536
    Abstract: A tool driving device for hole processing includes a spindle, an electric motor, a guide, an electric actuator, a sensor and a controller. The spindle has a holder for holding a tool for the hole processing. The holder is disposed at a distal portion of the spindle. The electric motor rotates the spindle. The guide has a positioning member for positioning the tool driving device to the workpiece. The electric actuator advances and retreats the spindle relatively to the guide in a rotation axis direction of the spindle. The sensor measures cutting resistance transmitted from the tool to the spindle. The controller is configured to control the electric motor and the electric actuator based on the cutting resistance measured by the sensor so that a rotating speed and a feeding speed of the spindle become a rotating speed and a feeding speed according to the cutting resistance.
