designed to perform a two coaxial internal diameter measurement check;
utilized after turning and grinding operations on transfer machines, special purpose machines and post-process gauging stations;
typical for the measurement of valve seat and valve guide diameters of the cylinder head.

The diameter measurement plug guarantees reliability and process productivity improvement by automation of the process itself inclusive of the part measurement and closed loop feedback to the machine tool (compensation of tool wear, improvement of overall machining time and scrap reduction).

Measurements are performed by use of four Marposs measuring cells, each provided with one LVDT transducer.

The diameter measurement plug uses a body with fixed nosepiece. In order to protect it from potential collision due to part mis-positioning or part overstock conditions, the plug requires mounting to rigid recoiling devices.

The diameter measurement plug is provided with cleaning air nozzles in the diameter no.1 section (the air inlet is always at 180¬? with respect to the junction box).

It can be connected to E9066N electronic unit for complex applications or applications for which statistical analysis is required and to E3 family electronic units for simple applications.

Side-by-side assembled on the machine, the gauge plugs can measure bores having minimum center distance of 47 mm.

Diameter measurement check can be costly in terms of time, labour costs and test equipment, so to know more follow the link: M18 Diameter Measurement Plug
