Hobbing Machines for Dry Cutting Applications
Star SU offers the Bourn and Koch 400 H seven-axis horizontal hobbing machine featuring a FANUC CNC and point-to-point array hobbing capability. The machine is designed for longer spline shafts as well as spur and helical gears ranging to 400 mm in diameter and 6.4 module. The machine can be configured for dry or wet hobbing.
The company also offers the FFG Werke Modul H200 vertical hobbing machine designed for dry cutting applications for small automotive applications, with the option of using oil or emulsion. According to the company, chips are cleanly conveyed from the work area by means of a chute, which is designed to prevent any buildup. The hob head is housed within the tool column, which is tightly fastened to the sturdy machine bed. The tailstock is located on the tool column above the hob head, designed to leave the work area free for workpiece loading and unloading operations.
Speed changes the rules. To maximize metal removal rate with a high speed spindle, follow some fundamental tooling considerations and mill at just the right rpm.
Many job shops start in a garage with a used mill and a manual lathe. The owners of this Utah job shop took a different tack. Along the way to a very successful business, they've debunked a bunch of myths commonly held about job shops.
Years of trial and error combined with the appropriate machining technology allow this company to produce custom parts made of alumina, zirconia, boron nitride and other advanced ceramic materials. One example of key machining technology is a five-axis machining center used exclusively to produce the complex, tightly toleranced geometry that fire-hardened workpieces require.
