Latest Patents
One of his latest patents is the "Guide mechanism for precision drilling and reaming." This apparatus is designed for precision positioning of guide bushings for roughing tools and finishing tools. It allows preformed holes in workpieces to undergo a roughing operation followed by a finishing operation. The guide bushings are mounted on the ends of carrier arms that encircle a workpiece holder. Each carrier arm is capable of swinging movement on a pivot axis, allowing for alignment with the holes in the workpiece. Power is provided for the simultaneous swinging of all carrier arms, enhancing operational efficiency.
Another notable patent is the "Eccentric spindle," which is an apparatus used for cutting a workpiece on different centers. The workpiece is mounted in a chuck on a spindle top, which is attached to a rotatable, vertical spindle shaft. This design allows the cutting tool to operate at different positions spaced apart laterally relative to the spindle shaft axis. By rotating the spindle shaft, the tool can cut the workpiece on various centers, providing versatility in machining operations.
