Skiving, Roller Burnishing System Speeds Surface Finishing

Sunnen’s SHD-series skiving and roller burnishing system is said to be 60 to 70 percent faster than traditional honing. It is engineered to deliver precise tolerances and quality surface finishes. The system may be used for a variety of part types and materials, including high-production, hydraulic cylinder applications. The SHD 2400 model is designed for part lengths up to 2 m, and the SHD-4400 model is designed for part lengths up to 4 m. The system finishes the internal diameters of workpieces in a single pass.

The system is built for easy setup and operation, and it is said to reduce cycle times. It is powered by a 57-kW (76-hp) Baldor spindle motor with ABB inverter drive for increased power, and heavy-duty 55-mm (2.16") linear rails for increased durability. Servo-driven, 80-mm (3.15") heavy-duty ball screws from Beckhoff 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 damper ensures smooth operation.
