摘要： An object is to provide an automatic correction device for a blade edge position capable of automatically correcting a deviation of a tool blade edge from a reference position due to an inclination amount of the tool blade edge and an orientation angle when a turning tool is mounted on a tool main spindle in an NC-controlled machine tool. The automatic correction device for a blade edge position at a time of a turning tool being mounted on a tool main spindle in a machine tool includes tool clamp surface inclination amount acquisition means, tool shaft rotation phase angle acquisition means, and tool protrusion amount acquisition means at a time of mounting the turning tool on the tool main spindle, and includes first correction arithmetic processing means for a blade edge position based on a tool shaft rotation phase angle with respect to an inclination amount of a tool clamp surface and a tool protrusion amount obtained by the acquisition means. Selected Drawing FIG. 1

摘要： [Object] Techniques are disclosed for tool holders that non-rotatably hold tools, which can prevent long continuous chips from wrapping around the tool or a workpiece.
[Solution] A tool holder 100 holds a tool 170 in a non-rotatable manner. When an attaching surface 112a of a body part (110, 120, 150) of the tool holder 100 is attached to a tool holder attachment surface of a machine tool, cooling medium supplied from the machine tool is conducted through a first body part passage (114, 124). Furthermore, a rotary member 130 is rotationally driven by a drive mechanism provided in the machine tool. As a result of a rotary part rotating in conjunction with the rotation of the rotary member 130, a pump 200 increases the pressure of the cooling medium suctioned from an inlet part 201 to a pressure corresponding to the rotational speed of the rotary part, and discharges the cooling medium, the pressure of which has been increased, from an outlet part 202. By way of a second body part passage (125, 115), cooling medium discharged from the outlet part 202 is sprayed from a spray hole 161 of a nozzle 160 onto a processed part.-

摘要： A tool turret comprises a turret body having at least one connecting slot for replaceably mounting a tool holder TH to the tool turret and a transmission shaft S arranged at the connecting slot. The transmission shaft S is configured to transmit a drive torque to the mounted tool holder TH. The transmission shaft S has a torque receiving-side section S2 for receiving driving torque and a connecting-side section S3 for connecting to the mounted tool holder TH. The connecting-side section S3 has a first gearing S4 for transmitting the drive torque to a corresponding tool holder gearing TH3, wherein at the torque receiving-side section S2 a contacting part is provided for receiving the torque of the drive unit. A mating surface is provided at the connecting-side section (S3) of the transmission shaft S and the mating surface is arranged to contact to a surface of the mounted tool holder TH for interacting with the tool holder TH to remove a gap between the first gearing S4 and the corresponding mounted tool holder gearing TH3.
