Title: Innovations by John V Hagan
Introduction
John V Hagan is a notable inventor based in Littleton, Colorado, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in grinding technology for bimetallic components, showcasing his expertise in engineering and innovation.
Latest Patents
One of Hagan's latest patents is for abrasive inserts designed for grinding bimetallic components. This invention outlines a method and apparatus for machining flat surfaces of a bimetallic engine block. The design includes a grinding wheel with a series of abrasive inserts strategically placed along the circumference of a circular head. This configuration allows the inserts to form a notional annular grinding ring during rotation. The head is typically a conventional milling head, and the inserts are crafted to fit into receptacles meant for standard milling inserts. An alternate embodiment features a second series of abrasive inserts positioned radially inward, creating an inner notional annular grinding ring that is concentric with the outer ring. Both inner and outer inserts are made with a single layer of diamond abrasive brazed onto a metallic substrate, enabling efficient grinding without the need for additional guarding.
Another significant patent by Hagan involves a grinding wheel specifically designed for grinding material from bimetallic surfaces. This grinding wheel consists of a first annular grinding element that is concentrically disposed on a backing plate. The first element includes either metal brazed single layer abrasive components or abrasive components bonded in a porous matrix. A second annular grinding element is also included, positioned concentrically inward of the first. Each grinding element is designed as a discrete unit, allowing for independent height adjustments relative to the backing plate. This innovative design simplifies both the assembly of the wheel and the height adjustment process.
