In 1985, Bourn & Koch, Inc. acquired the machine tool division of Barber-Colman. Since then, we have continued the tradition of manufacturing world-class gear manufacturing machines in Rockford, Illinois. Our gear manufacturing machines are designed and built just a few short miles from where Barber-Colman once did the same. Our H-Series Hobbers can produce AGMA Class 13 gears without grinding. Cutting gears to that level of excellence starts with the precise manufacture and assembly of our machines. Our in-house machining capabilities combined with precision assemblers ensure that every machine we build is well-crafted and designed to last.
Bourn & Koch manufactures our H-Series Hobbers in four sizes from our 25H with a pitch range of 1 module to up to our 600H with a massive 12 module pitch range. Our HDS 1600-300 herringbone gear generating machine is a revolutionary addition to our already impressive offering of gear manufacturing machinery. Each machine is CNC-controlled with servo-motion control on precision linear roller ways, hand-scraped bearing surfaces and accurate ball screws for easily achieving high tolerances. Our conversational HMI guides the operator through the gear cutting process, reducing specialized training required to run the machine. Designed to cut external spur and helical gears, each H-Series Hobber is a versatile tool crafted by precision machine tool builders with decades of experience.
