The SVC-310 vertical CNC honing system from Sunnen sizes small and medium gas/diesel engine blocks, large gears, air compressors, aerospace parts, refrigeration compressors and other multi-bore parts using multi-spindle configurations with 762 mm stroke and a variety of tooling options.

 

The honing system’s work envelope is 1,016 mm x 1,778 mm, and it has a maximum weight capacity of 909 kg. The bore profile is displayed during cycle by a straightness sensing feature, so along with a servo stroking system, the SV-310 can auto-dwell at any point to adjust bore straightness. The system is capable of honing parts up to 710 mm long with inside diameters ranging from 19–200 mm.

 

The machine was configured with full-height access doors and enclosure, so robotic part loading systems can be used to produce mid– to high–part volumes. Automation is controlled by a 20-amp power supply while a three-axis hand wheel helps place x-axis position, vertical stroke and tool feed. The touch-screen control allows operators to program multiple bore positions with an unlimited capacity for job setups.

 

The SV-310 has a rigid base made from malleable iron. A ballscrew drives the straight-line stroke motion at 1–160 strokes per minute, and torque is provided by a 5.5 kW spindle for removing metal quickly. The machine’s horizontal and vertical guide ways are lubed-for-life.
