The SV-500 Series vertical CNC honing system from Sunnen Products profile-hones diesel cylinder liners. Patented technology creates whole-bore, constant crosshatch, and custom profiled or tapered bores. Available with a stroke length up to 1524 mm (60 in), the SV-500 Series' 15-kW (20-hp) spindle is suitable for bores up to 300 mm (12 in) diameter and permits removal rates on materials such as titanium and iron. Standard spindle speed is 0 to 300 rpm, with a maximum stroke rate of 27.4 m/min (90 ft/min). An electromechanical design eliminates drift, while the open-base, vertical design allows pass-through of large parts and conserves floor space. Stainless-steel guarding is maintenance-free. The series is suitable for low- to mid-volume machining of oil and gas components, including gas compressors, valves, and pump liners.
