Multifeed Honing

May 5, 2011

Sunnen’s new multifeed honing technology gives users a choice of tool-feed modes to achieve the shortest cycle times, lowest part cost, and longest abrasive life, the company reports.

The multifeed system combines the company’s controlled-force tool feed with its controlled-rate feed system. The two different tool-feed modes allow the user to select the best option to suit the workpiece geometry, material, and tool type and size. Multifeed technology is available as an option on the company’s new SV-1000 and SV-500 series, as well as a retrofit for existing machines in these series.

Controlled-force honing, a new feature in multifeed, ensures the optimum cutting load on the honing abrasive throughout a cycle, regardless of the incoming part’s hardness, geometry, or size variation.

Depending on the application, controlled-force honing can cut cycle time by as much as 50 percent, lengthen abrasive life, and allow finer control of surface finish parameters, the company states. It also eliminates glazing of the abrasive, caused by too little force being used, and maintains a steady, free-cutting, self-dressing condition for maximum metal removal.
