Abstract: An angle spindle attachment for a vertically movable spindle unit is provided for rotating a cutting tool in a generally horizontal orientation. The attachment includes a spindle assembly having a drive train that is mechanically independent from the drive train of the vertically movable spindle unit, and a connector block for detachably connecting the spindle assembly at a transverse angle with respect to the vertically movable spindle unit. The connector block may include an angular adjustment mechanism that allows the spindle assembly to be oriented at an angle above or below the horizontal, as well as a rotational adjustment assembly that allows the spindle assembly to be pivotally adjusted about the axis of rotation of the vertically movable spindle unit.

Abstract: An apparatus is provided for transmitting rotation about and translation along a first axis from a driver to a toolholder with a spindle along an axis non-parallel from the first axis. A shaft is rotatably mounted within a sleeve which is slidably mounted within a bore along the first axis. The sleeve has an inclined surface at one end which when the sleeve is translated engages an interface member to provide displacement.
