Sunnen’s patented multi-feed honing technology gives gear manufacturers a choice of tool-feed modes to achieve the shortest cycle times, lowest part cost, and longest abrasive life. Multi-feed combines Sunnen’s new controlled-force tool-feed with its controlled-rate feed system. The two different tool-feed modes allow the user to select the better option to suit the workpiece geometry, material, and tool type/size. Multi-feed technology is available as an option on Sunnen’s SV-1000 and SV-500 machines, as well as a retrofit for existing machines in these series. The new controlled-force tool-feed capability maintains an optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part’s hardness, geometry or size variation. It is an ideal choice for applications using segmented diamond or superabrasive honing tools, such as Sunnen’s MMT, PH, or KRQ tools, or where incoming gear blanks have slight variations in hole diameters, hardness, and geometry. Depending on the application, controlled-force honing cuts cycle times by as much as 50 percent, lengthens abrasive life for lower consumable cost, and allows finer control of surface finish parameters. The new technology eliminates glazing of the abrasive, due to too little force, and maintains a steady, free-cutting, self-dressing condition for maximum metal removal in the shortest possible cycle time. Controlled-force honing often allows more-durable abrasives to be used, too, resulting in more parts per set of abrasives and lower cost per part. Learn more at [www.sunnen.com].
