Abstract: This invention relates to an automatic precision apparatus which includes an elongated rotatable central shaft concentric with and encased by a fixed outer cylinder. A rotary workpiece table is fixed to the central shaft adjacent one end of the central shaft, and a round tool holder table is fixed to the cylinder adjacent one end of the cylinder and disposed in spaced relationship with the rotary table and in parallel arrangement with the rotary table. A plurality of spaced tool holders are disposed around the round table, and a plurality of equally spaced workpiece holders are disposed on one surface of the rotary table facing the round table. Each tool holder is precisely aligned with a respective one of the workpiece holders and is alignable with every other one of the workpiece holders.
