High Tech Inspection Equipment and Processes

Our inspection process is differentiated by our high-tech equipment and processes, including our Shop Floor Hexagon 7-8-7 CMM Coordinate Measurement Machine. This equipment is utilized in cellular manufacturing to ensure that the non-value-added in-process inspections are done during the machining process. The shop floor measurement machine is additionally advantageous because it will not create additional queues during the machining process.

Other pieces of equipment that will save customers both time and money include:

  • Air gage technology, accuracy ±.00005 
  • Digital Calibration and Recall System
  • Digital Rockwell Hardness Inspection equipment HRA, HRB, and HRC
  • Statistical process control
