vertical CNC honing system

Description

Sunnen's new SV-310 vertical CNC honing system combines multi-spindle machine configurations with wide tooling choices and 762mm/30" stroke for bore sizing of small and medium-sized gas/diesel engine blocks, large gears, air compressors, aerospace parts, refrigeration compressors and similar small or large multi-bore parts.  A work envelope of 1016mm x 1778mm/40" x 70" and weight capacity up to 909 kg/2000 lb provide versatility for processing a wide range parts.  An optional tool-guide assembly and variety of bore-diameter gaging systems combine with a servo-controlled X-axis travel of 1143mm/45" to allow automated honing of multi-bore blocks with high precision.  Straightness sensing capability provides a display of the bore profile during the cycle.  Combined with a patented, servo stroking system, it allows the SV-310 to auto-dwell in any part of the bore to correct straightness automatically in the shortest cycle time.  The SV-310 can be used to hone parts with inside diameters from 19-200 mm (0.75-8.00"), depending on the tool options selected.
    Designed from the ground up for automated processing of mid to high part volumes, the SV-310 features full-height access doors and enclosure preconfigured for use with robotic part loading systems, while the CNC control includes a built-in automation interface. A 20-amp power supply and multiple E-stop contacts add versatility and allow convenient automation control.  Setup is simplified with a 3-axis hand wheel for fine-tuning X-axis position, vertical stroke, and tool feed.  The Windows®-based, color, touch-screen control features multi-language capability, pull-down menus, unlimited capacity for job setups, and programmable custom tools.  In addition to optional in-process air gaging, a variety of optional post-process air-gage systems can integrate with the control for SPC data collection, as well as automatic compensation of size, taper and straightness. The control allows easy programming of multiple bore positions.
    The SV-310 is built on a malleable iron base for rigidity and vibration damping.  The machine's servo-controlled, straight-line stroke motion is driven by a ballscrew at rates of 1-160 strokes per minute, while a powerful 5.5 kW/7.5 hp spindle provides ample torque for fast metal removal with tools outfitted with metal-bond cubic boron nitride and diamond abrasives or standard aluminum oxide and silicon carbide stones.  Oversized, lubed-for-life guide ways for horizontal and vertical axes provide smooth operation and long, maintenance-free life.  An optional T-slot table 800 x 1545 x 45.5 mm can be mounted on the casting base, along with an elevated fixture frame for holding all types of fixtures.
    The SV-310 can be equipped with a wide range of Sunnen tooling, such as the new PH precision multi-stone tool. The PH tool can hold as many as 12 stones for optimum straightness and roundness on bores 3.00-7.5"/76.2-190.5mm, while delivering high efficiency in mid- and high-volume production.  It is available in single or two-stage configurations, along with optional, integral air-gaging for in-process monitoring.
