摘要： Systems and methods include using a pull stud bolt for connecting a tool holder to a collet in a spindle. The pull stud bolt includes a body configured to receive a tool holder, the body having a longitudinal passage fluidly connected to a cavity, the cavity fluidly connected to a plurality of longitudinal channels; a sealing ring disposed around an end of the longitudinal passage, the sealing ring in contact with the cavity; a spring disposed in the cavity; and a sphere in contact with the spring. The sphere is configured to unblock the end of the longitudinal passage by losing contact with the sealing ring when a first force applied to the sphere from the spring is less than a second force applied by a fluid flowing through the longitudinal passage. The first and second forces are substantially opposite in direction of application.

摘要： A retention knob for use with a tool holder that is less prone to distorting a tapered tool holder surface, especially if it is over-tightened. The retention knob includes a knob head, a flange engageable with an end of a tool holder shank, a pilot segment receivable by the counter bore defined by said tool holder shank and a threaded segment spaced from said flange by an undercut segment. The threaded segment is configured so that it has a length that is substantially the minimum length required to achieve maximum thread holding strength. The undercut segment is configured to space the threaded segment from its head so that a distal end of the threaded segment is substantially near the bottom of the tapered bore forming part of the tool holder.

摘要： A tool holder (10, 10') includes a body (12, 112), a cutting head (14, 114) having a cutting end portion (38, 138) and a tapered end portion (42, 142), a retention knob (16, 116) located at the tapered end portion of the cutting head, and a ball clamping mechanism (20, 120) received in an aperture (34, 134) of the body. The ball clamping mechanism includes an upper clamp (22, 122), a lower clamp (24, 124), and a double-ended clamp screw threaded (26, 126) onto the upper and lower clamps. Rotation of the clamp screw in a one direction causes the upper clamp and the lower clamp to move toward each other and engage the retention knob to place the tool holder in a locked position, and rotation of the clamp screw in an opposite direction causes the upper clamp and the lower clamp to move away from each other such that the upper and lower clamps no longer engage the retention knob to place the tool holder in a unlocked position.
