PRODUCT SHOWCASE: New Single-Pass Honing Machines from Sunnen


Sunnen is introducing the new VSS Series 2 single stroke® honing systems at IMTS, offering the most accurate spindle alignment in the industry combined with flexible, easy-to-use controls. Spindles on VSS-2 machines are factory aligned, independently, for precision centering of the spindles and tooling plate to produce better bore geometry than possible with machines that use an “average” alignment for all the spindles. Alignment accuracy exceeds DIN 8635 requirements for vertical honing machines. VSS-2 Series machines incorporate up to six spindles to progressively size and finish part bores with tools of preset diameter and grit size. The machines are ideal for precision sizing of bores 3.9-50 mm (0.149-2.0") diameter in stamped parts, hydraulic valve bodies, gears and sprockets, parking pawls, rocker arms, turbocharger housings, and similar parts. Appropriate materials include cast iron, powdered metals, ceramic, glass graphite, and other free-cutting materials.
