Sunnen’s SV-15 honing machine combines the DNA of the legendary Cylinder King machine with a Siemens touchscreen PLC to provide more features, convenience, and even greater precision and consistency than the “King” of motorsports honing. A real-time display of the bore shape allows the operator to confirm bore straightness and make on-the-fly adjustments to correct taper – or simply confirm the action of the auto-dwell feature that efficiently concentrates honing action in tight spots. The control automatically switches from roughing cycle to finishing cycle for fast processing with the optimum finish, geometry and crosshatch angle. One hundred setups can be stored in the control, and additional storage with a USB flash drive can provide even more. The control eliminates belt/pulley adjustments, as well as all pushbuttons (except E-stop)
The U.S.-made SV-15 is a versatile automatic cylinder hone capable of handling bore diameters from 0.750″ to 8″ (19-203 mm) and lengths up to 11″ (279 mm) for all types of blocks, from single-cylinder and high-performance engines to diesel truck and industrial blocks up to 46″ (1168 mm) long. With separate spindle and stroker motors – 3 hp/2.25 kW and 1 hp/ 0.75 kW respectively – the SV-15 can run standard Sunnen tools as well as the DH-series diamond hone head. High surface contact with the multi-point DH tool produces the roundest bore possible for excellent sealing with today’s thinner rings.
Variable spindle and stroker speeds – adjustable while in cycle – enable infinite crosshatch angles for any bore diameter and cylinder length combination. Precise zero shutoff ensures automatic, consistent size on every bore.
The SV-15’s standard multi-position rollover fixture handles most automotive blocks, and the optional CK-6200 clamp kit further expands the range of blocks that can be accommodated. The machine’s honing fluid reservoir/filter system holds 55 gallons (206 liters). Removable settling tanks, screens and filter cartridges (two) are designed for easy servicing and replacement.
