Sunnen’s SV-1005 series vertical CNC honing system is now available with an integrated air gaging system to provide closed-loop control of tool size, along with downloadable SPC data. Matched with Sunnen’s diamond-plated CGT Krossgrinding® tools or MMT TurboHone® multi-stone mandrel, the air-gage-equipped machine can automatically control hole size to accuracies of 0.25µm (0.000001") without operator intervention, working in a size range of 3 65 mm (0.120-2.56") diameter. It is ideal for automated, high-Cpk production of small engines, hydraulic valves/bodies, fuel injectors, gears, compressor parts, turbocharger housings, and gun barrels, in medium and high volumes.

According to Dolph Schallenberg, sales manager for Sunnen Products Company, by combining the new air-gaging system with the machine’s patent pending tool-feed control, the SV-1005 eliminates the need for an experienced honing operator to tweak the process. The new Etamic air gaging system controls bore diameter and geometry by taking post-process measurements of the parts while they are still fixtured on the machine’s rotary table. Feedback from air gage provides the highest possible accuracy for tool-feed control.

The SV-1005 matches an ultra-precise tool feed system with CNC control to allow any CNC-experienced machinist to master honing quickly. Setup is simple, with a three-axis hand wheel for fine tuning the tool feed and the servo-controlled stroke system and rotary table. The control includes several features that put honing expertise at the fingertips of novices, such as a switchable autocorrect feature for bore shape. Using measurements from the air-gage system, it allows the operator to select from a library of “problem” bore images (taper, barrel, etc.) to match to the part on the machine. The servo-controlled stroke system ensures a consistent crosshatch pattern and can dwell in any part of the bore, end-to-end, selectively removing stock for ultra-precise straightness and roundness.

The vertical design of the SV-1005 conserves shop floor space, requiring just 2400 x 2300 x 2700 mm WxDxH (95 x 91 x 107 in.). A cast polymer base and cast-iron column provide enhance vibration damping for precision honing, while removable stainless steel side doors facilitate integration with automatic part loading systems. The high-torque, belt-driven spindle is rated at 7.5 kW (10 hp) to cover a wide range of sizing and finishing work using Sunnen’s MMT TurboHone multi-stone mandrels, TC precision mandrels, or CGT Krossgrinding tools.
