  • Gear Hobbing

    Hobbing is the most frequently used method of making gears. A gear hob is a cylindrical cutting tool with rings of teeth that are the involuted shape of the desired gear tooth. The gear hob is positioned at a right angle to the gear blank being cut. In this manner the gear blank rotates with the hob feeding across the cutting plane. Each successive tooth on the hob cuts a little deeper until it has generated the precise gear tooth profile desired.

    Broaching

    Broaching is a machining process that finishes a simple or complex bore by pulling a multi-tooth tool called a broach through the part. Because the part is finished in one pass, broached parts are inexpensive and true to size.

    Deep Hole Drilling

    Gun drilling is an ideal solution for most deep and precision drilling projects. The gundrill consists of a hollow tube with a " V" shaped groove or flute along its length, and a carbide cutting tip designed in such a way as to produce it's own guide bushing as it drills the hole. This high precision operation produces accurate, repeatable holes, with excellent surface finishes.

    Hobbing, Broaching and Deep Hole Drilling
    Hobbing Broaching
    Our gear department is equipped to handle all types of gear cutting. We use Barber Colman hobbing machines for worm, worm wheel, spur and helical gears. We provide complete gear manufacturing or cut teeth only on customer supplied blanks. Let us know how we can help you and we will work with you to meet your gear manufacturing needs. The broaching process has been used by many industries for years and yet it remains a useful and efficient method of metal removal that sometimes cannot be achieved by other means. Our vertical pull-style-broaching machine can cut keyways - both english and metric, involute and straight splines, hexagons, and squares as well as special forms on internal diameters.

    Barnes Gundrill Eldorado Knee Type Digitally Controlled Gundrill Barnes Gundrill
    Current deep hole drilling equipment consists of Barnes gundrills for on-center drilling and a Eldorado knee type digitally controlled gundrill for off-center drilling. Drilling sizes range from .078" to 2" with depth capabilities exceeding 60", from one end, depending on the part configuration and hole size. DTI stocks a wide variety of drill sizes and lengths to eliminate production delays caused by waiting for drills. Let us show you how DTI delivers more "Value-Added Services" to our customers and partners.
