Low cost per large, heavy honed part

The new Sunnen SV-2010 AXYS CNC honing system solves the challenge of honing large, heavy parts such as cast-iron hydraulic valve blocks and bolted assemblies common to heavy-duty machinery used in the mining, off-road and construction industries. These parts are historically difficult to fixture and hone, and Sunnen says that its SV2010 AXYS sets a new industry standard for cost-efficiency in these applications

Built around Sunnen’s field-proven SV-2000 series honing column, the system integrates the vertical honing column with a high-resolution (20 million pixel) industrial camera and a heavy-duty i5 CNC controlled servo X-Y table to facilitate precise bore positioning accuracy within 0.02 mm.

The operator loads the part, hits the start button, and the system automatically finds the centreline of each bore. Then, the machine automatically hones each bore to specification, in sequence. The operator is free to complete other tasks while the machine completes the part, exponentially increasing operator efficiency and productivity. Easy to use, intuitive controls reduce set-up time and operator training requirements. The 7.5 kW high-torque output servo honing spindle allows the machine to short-stroke or dwell in any part of the bore. The system’s automation and precision honing technology deliver low cost per honed part, while hitting tight bore tolerances.

Machine weight is approximately 6350 kg, with a rugged, solid cast-iron base and honing column to reduce vibration, increase rigidity and enhance performance. The system handles parts with bore diameters from 5‐65 mm, while the part maximum envelope is 600 mm (L) x 300 mm (W) x 300 mm (H), and the maximum part and fixture weight is 800 kg.
