Skiving, Roller Burnishing System Offers Alternative to Honing

Sunnen streamlines the skiving and roller burnishing processes with the SHDS series system. "The result is a system that is 60% to 70% faster than traditional honing and engineered to deliver precise tolerances and quality surface finishes," said a company spokesperson.

The skiving and roller burnishing process may be used for a variety of part types and materials, and it is especially suitable for high production hydraulic cylinder applications. Available in 2 m, 4 m and 6 m part-length capacities, the system is designed to finish the inside of diameter of workpieces in a single pass.

"Only Sunnen offers both honing and skiving/roller burnishing solutions, so we are able to provide a completely objective consultation for the most cost-effective bore finishing process for each specific bore sizing application," said Phil Hanna, Sunnen Product Manager. "The SHDS systems were designed with extensive customer input and are easy to set up and use, providing superior finishes and dramatically reduced cycle times. Plus, we offer the complete solution with machines, tools, coolant systems, cutting fluids and chip management, all designed to work together."

The SHDS is powered by a 27 kW (38.5 HP) spindle motor with inverter drive for optimum power and heavy-duty 55 mm (2.16") linear rails for maximum durability. Beckhoff servo driven heavy-duty ball screws handle tool feeding and part clamping. An automatic chip removal system eliminates waste from the skiving/roller burnishing process, and a heavy-duty tool-drive shaft vibration dampener provides smooth operation.

The SHDS accommodates bore diameters from 38 mm to 178 mm (1.5" to 7.0"). A full range of individual or combined skiving/roller burnishing tool assemblies are available for use on non-Sunnen machines. Sunnen's SCO-885 cutting oil provides optimal lubricity and chip flushing for long tool life and enhanced surface finish.
