  • Patent number: 8893362
    Abstract: A turret tool holder, having structure capable of easily avoiding unnecessary free rotation of a turret, is provided. When a linearly movable shaft is moved toward a turret head section by driving a servomotor, an annular movable coupling element arranged in the turret begins to disengage from an annular fixed coupling element fixed to a support. While the movable coupling member is still engaged with the fixed coupling member, clutch teeth of a clutch member are engaged with other clutch teeth. Therefore, even when the annular movable coupling element is disengaged from the annular fixed coupling element, the turret is prevented from freely rotating by the engaged clutch teeth.

The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor supports a cutting tool that is retained in the adaptor by a clamp. The cutting tool defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder is also disclosed.

  • Publication number: 20080178718
    Abstract: A rotational power servo toolpost includes a plurality of rotational tool holders, which can freely rotate 360 degrees, to cut a workpiece from various angles. The rotational power servo toolpost has a turret base, a turret, tool holders mounted on a side surface of the turret and having a variety of needed tools, a tool-holder-rotating device, and a tool-rotating device. When the tool holder with the needed tool rotates along with the turret to the preset area, a servo motor of the tool-holder-rotating device drives the related members to freely rotate the tool holder around 360 degrees according to the machining requirements. The tool-driving device then drives the tool, thereby cutting the workpiece from various angles.
