Model 911

Model 911 Cylindrical Coordinate Measuring Machine

The Adcole Model 911 is the world standard for camshaft measuring throughout the reciprocating engine industry. This gage is also ideal for measuring pistons, pump rotors and housings, transmission shafts and any other cylindrical components. The system delivers unsurpassed accuracy, speed and ease of use, whether on the shop floor or in a separate gage lab.


  • Accept new machine tools and verify grinders/polishers
  • Audit production parts and incoming inspections
  • Research and development work
  • Provide direct input to machine tools
  • Reduce fixture gage expense
  • Minimize scrap and rework
  • Measure more parts


  • Cam lobes (intake, exhaust, injector, brake)
  • Symmetrical or asymmetrical
  • Cylinders
  • Pump rotors and housings
  • Eccentric shafts
  • Splines
  • Tapers

Adcole gages can be located in clean inspection lab environments or right out on the shop floor. Measured results are displayed on a touchscreen monitor and can be printed/plotted or simply up-loaded electronically for historical tracking.


Vertical part orientation provides the optimum measurement results with no need for sag correction while minimizing floor space requirements. The tailstock can be adjusted very simply to compensate for changes in part lengths. Parts are rotated and measured for a full 360 degree analysis of each feature.
