CNC Honing System For Bore-Sizing Applications
Sunnen's SV-400 vertical CNC honing system is designed for bore sizing of small- and medium-sized gas/diesel engine blocks, oil/gas and hydraulic/pneumatic components, and other multi-bore parts. A work envelope of 915 x 1015mm (36 x 40in) and weight capacity up to 90kg (2000lb) provide versatility for processing a range of parts. An optional tool-guide assembly and variety of bore-diameter gauging systems combine with a servo-controlled X-axis travel of 1143mm (45in) 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 servo stroking system, it allows the SV-400 to auto-dwell in any part of the bore to correct straightness automatically in the shortest cycle time. The SV-400 can be used to hone parts with inside diameters from 19-200mm (0.75-8in), or diesel liners up to 150mm (6in) depending on the tool options selected. It 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 20A power supply and multiple E-stop contacts add versatility and allow convenient automation control, according to Sunnen. Set-up is simplified with a multi-axis hand wheel for fine-tuning vertical stroke, tool feed, column position (SV-410 only) and optional cradle position. Automatic tool feed can be selected for constant load or constant rate. The PC-based colour 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 gauging, a variety of optional post-process air-gauge systems can integrate with the control for SPC data collection, as well as automatic compression of size, taper and straightness.
The control allows easy programming of multiple bore positions. The SV-400 series 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 7.5kW (10HP) spindle provides ample torque for fast metal removal with tools outfitted with metal-bond cubic boron nitride and diamond abrasives or standard aluminium 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 measuring 800 x 1545 x 45.5mm can be mounted on the casting base, along with an elevated fixture frame for holding all types of fixtures. SV-400 machines can be equipped with a range of Sunnen tooling, including General Hone, GHTS, PH, CV/VK, P20/P28, HB and the PH precision multi-stone tool. The PH tool can hold as many as 12 stones to produce optimum straightness and roundness on bores, while delivering high efficiency in mid- and high-volume production. It is available in single- or two-stage configurations, along with optional, integral air-gauging for in-process monitoring.
