Sunnen's SV-500 vertical honing system

Designed for bore diameters of 19-300 mm, its 15 kW spindle permits high stock removal rates on tough materials, such as compacted-graphite iron. Standard spindle speed is 0-300 rpm, with options of 0-600 and 0-1200 rpm, and a maximum stroke rate of 160 per minute. Available in single and multi-spindle configurations. It is designed to automatically correct bore geometry and size, while producing a constant crosshatch angle and surface finish, end-to-end, throughout a bore. The SV-500's synchronized servo axes allow the operator to set the desired crosshatch angle through the Windows-based control, or change it mid-cycle, eliminating the "flattening" of the crosshatch angle that is inherent at the stroke-reversal points for other honing machines. For unmanned processing, the SV-500 can be equipped for in-process air gauging with Sunnen's PH hone head, or with post-process air gauging, to provide closed-loop control of bore size and geometry, along with downloadable SPC data. Part indexing options include in-line shuttles for transfer lines, as well as 2 and 32 position rotary tables or (fourth axis) servo-index table with infinite positioning. The open base of the SV-500 allows easy pass-through of large parts and makes the SV-500 adaptable for parallel manufacturing in a lean environment. The machine's vertical design conserves shop floor space and it measures 2,210 by 2,056 by 2,275 mm without coolant tank. A modular design allows processing solutions to be custom designed, end to end, for a wide range of parts, production rates and specific customer needs.
