These problems led Mark Zupan, president of Micron Manufactur ing, to re place the multi- spindle manual diamond sizing machine with a fully automated one-spindle Nagel Eco 40 honing machine with post process gaging and automatic wear compensation. The one-spindle Eco 40 stroke honing machine consists of a servo with four axes—one each for spindle rotation, stroking, tool expansion and rotary-table actuation. It is controlled by an AB ControlLogix PLC. The post process/final gaging system provides feedback to the automatic wear compensation system within the honing spindle. By gaging every par t, bore size can now be monitored on 100 percent of parts and submicron adjustments can be made to compensate for tool wear.

Nagel's Eco 40 can accommodate simultaneous part handling, honing and post process gaging. 0614_MMS_better.indd 140 5/14/2014 8:50:21 AM
