The SV-1005 series vertical CNC honing system with integrated air gaging system provides closed-loop control of tool size and downloadable SPC data. Matched with the company’s superabrasive MMT tool, the air-gage-equipped machine can automatically control hole size to 0.25-µm (0.00001") accuracy within a size range of 3 to 65 mm (0.12" to 2.56") in diameter. It is suited 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 the company, combining the air gaging system with the machine’s tool-feed control eliminates the need for operators to tweak the process. The air gaging system controls bore diameter and geometry by taking post-process measurements of the parts while they are still fixtured on the rotary table. Air gage feedback provides high accuracy for tool-feed control, the company says.
 
The honing system matches an ultra-precise tool feed system with a CNC to enable any CNC-experienced machinist to master honing quickly, the company says. To set up, a three-axis handwheel fine-tunes the tool feed, the servo-controlled stroke system and the rotary-table. The control includes a switchable autocorrect feature for bore shape. Using measurements from the air-gage system enables 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, to selectively remove stock for precise straightness and roundness.
 
The vertical design of the honing system requires 95" × 91" × 107" (2,400 × 2,300 × 2,700 mm) of floor space. A cast polymer base and cast iron column enhance vibration damping, 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 range of sizing and finishing work.
