Patent ID: 7988531

Claim:
Grinding machine, comprising: a machine bed, a Y-carriage that is linearly movable in only a Y-direction parallel to a Y-axis on the machine bed, a rotationally-driven tool spindle mounted on the Y-carriage and configured to be rotatable around an X-axis perpendicular to the Y-axis while remaining aligned with the X-axis, an X-carriage that is linearly movable in an X-direction parallel to the X-axis on the machine bed, a Z-carriage that is linearly movable on the X-carriage along a Z-direction parallel to a Z-axis perpendicular to the X-axis and the Y-axis, a drive operably connected to the Z-carriage, and a work piece jig connecting with the Z-carriage and configured to pivot around a B-axis which is parallel to the Y-axis, and configured to rotate around a rotational A-axis which is perpendicular to the rotational B-axis and further comprising a tool magazine for holding tools, the tool magazine coupled with the X-carriage and offset from the Z-carriage in the Y-direction.
