overview Generating Heads For facing, recessing, boring, and contouring. Multiple operations can be performed faster, more economically, with better quality, and at one spindle location. Used on special-purpose machines and other high production machinery, including transfer lines and dial machines. ■ Single or double-slide models are available, designed for feed-out or feed-in ■ Sizes from 100 to 250mm (3.937 to 9.842 in.) in diameter ■ Drawbar actuation- no need to pilot in part or fixture ■ Unique actuator design- smooth, accurate motion for precise repeatability ■ Internal mechanism manufactured to exacting tolerances- backlash is virtually eliminated ■ All moving parts are hardened and precision ground for lasting accuracy ■ Built-in lubeways and easily accessible grease fittings ■ Equipped with through-tool auto lube capability ■ Special lightweight slides are available (optional) for higher cutting speeds and shorter cycle times- tooling can be balanced CUSTOM-DESIGNED Custom-designed top tooling is mounted in qualified Operations such as boring, turning, facing, chamfering, and holes on the toolslide. Standard inserts are used for form cutting can be easily performed. Generating heads can most applications. Special head designs and special often be made to perform multiple operations in a single pass form cutters are available. – this provides for optimum efficiency and performance in your machining operations. Cogsdill generating heads are designed to work on machines where the tool slide stroke is controlled by a Cogsdill generating heads are made from the highest quality drawbar. The drawbar can produce finite, accurate materials, to exacting quality standards. Our engineers have built movements in the tool slide(s), allowing the head to in quality features that ensure durability and consistent accuracy. perform accurate machining operations. Drawbars can These high-quality features include hardened and ground either push or pull on the actuator, and may be components, multiple grease fittings with internal lube ways, and controlled by CNC, hydraulic, or mechanical action. anti-friction coatings on wear surfaces. 39

Operating Principle Generating HEADS The method of operation incorporated in all Cogsdill generating heads is based on the principal of a sliding inclined wedge. This actuation mechanism produces smooth, linear cutter movement with little or no backlash. Generating Head sliding Cogsdill generating heads can be utilized on a variety of drawbar- inclined equipped machines such as transfer lines, rotary transfer wedge (dial type) machines, and other special purpose machines. The heads can mechanism and lubeways be mounted on virtually any spindle that has a drawbar. Cogsdill can provide a...

Features & Options Generating HEADS Cogsdill generating heads are available as standard products in single-slide and double-slide models, ranging in diameter from 100mm to 250mm (approximately 4 to 10 inches). The head type used generally depends on the operation(s) being performed and the speed at which the head is run. Top tooling packages can be designed by our engineers to suit individual requirements. Specially designed heads are available when required to meet unique part requirements or production challenges. Auto-lube Our auto-lube feature enhances the longevity of the generating...

Features & Options Generating HEADS (continued) Drawbar Force Requirements Requests for Quotation The drawbar force required to actuate the generating head is dependent upon three variable but interrelated factors: All quote requests should be submitted through our customer service department. ■ Size of generating head ■ Spindle speed or cycle time requirement ■ Weight of top tooling As the size of the head increases, so does the required drawbar force. Cycle time requirements can also directly affect the spindle speed. In some cases, the use of high strength aluminum alloy cross slide(s)...
