Sunnen's SV-1000 vertical CNC honing machines are based on a modular design and engineered to scale up from a single-spindle machine to a fully automated multispindle unit for precision bore sizing and finishing. They are designed for part diameters of 3-65 mm and can size bores to accuracies of 0.25 µm. Applications include diesel fuel injectors, gears, small engine cylinders/connecting rods, and hydraulic/pneumatic components. Removable side enclosure panels facilitate flow-through part processing. The basic single-spindle module comes with a fixed tooling plate or servo rotary table with 12-position rotary air union for fixture control. Industrial PC control ensures reliability and a support path with software-based updates and commercially available replacement parts.
