Valve Seat Inspection Gauge

M9R - M9RS

M9R and M9RS are the next generation of motorized handheld gauges for valve seat inspection on cylinder heads.

The gauges measure form parameters and all the profile features of the valve seat, thanks to the integrated scanning system.

The robustness of the structure, combined with the special transmission joint and the high precision motion control ensure easy handling and excellent performance over time, minimizing the operator influence.

The software platform drives the user step-by-step all along the inspection plan of the cylinder head, guaranteeing fast and precise operations as well as a clear results analysis.

Valve Seat Inspection Gauge
DESCRIPTION

M9R and M9RS are suitable for the quality control of the cylinder head across many market sectors, including gas and diesel engines for two wheelers, light and heavy weight vehicles and others. M9R is a robust and cost-effective solution for runout and roundness inspection of valve seats: rapidity and ease of use make this gauge the perfect tool for any manufacturing dimension.

The operator introduces the gauge into the valve guide and starts the measuring cycle by pressing the button on the plug handle or on external push-button. The automatic rotation allows to quickly perform the measures of runout (between valve seat and guide) and roundness (of the seat), processing the signals from two different probes located in the plug nosepiece, in combination with the mechanical reference of the gauge. M9RS offers unique features enclosed in a single instrument, thanks to the integration of the Marposs patented scanning system.

It performs two dynamic inspections, by rotating and scanning the entire valve seat in the same cycle, providing the runout, roundness and the measures of angles, seat straightness and seat length. Upon request, it can also run a custom inspection cycle to expand the number of features to be controlled in the valve seat.

The special transmission joint and the pre-centering guide protect the measurement cycle against operator movements, minimizing their effects. Several modes to use the gauges: free hand use, free-standing system with pre-centering guide, moved with a mechanical fixture or, in some specific cases, also on automatic system.

Anyone can easily operate the M9R and M9RS, thanks to the Marposs Guided Sequence Flow Control (GSFC), the software platform designed to drive the user all along the inspection plan of the cylinder head and during zeroing operations.

The standard scope of supply is composed by two plugs (M9R o M9RS) for intake and exhaust seats, the relevant masters, GAGEPOD™ MC8 driver units, supports and software. An industrial or commercial PC with Quick SPC installed is required to run and manage the application program.

BENEFITS
  • Fast and extremely precise inspections to enhance the production process
  • Robustness and reliability for excellent performances also under continuous measuring operations
  • Clear and detailed analysis of the part under inspection
TECH SPECS

Typical Valve Seat Dimensions

Traditional cylinder head markets: two wheelers, light and heavy weight vehicles, marine, gas engines and others.

  • Ø Valve guide (mm): 5 -10
  • Ø Valve seat (mm): 22-50
  • Seat Length (mm): >1
  • Seat Cone Angle (°): 60-120
  • Deck and Throat Angles (°): ± 20-40, respect to the seat angle

All the above values represent the typical application range. Upon request, it is always possible to evaluate and offer special solutions to measure valve seats with dimensions out of the specified range.

Gauges Dimensions

  • Width (mm): 44
  • Length (mm): 146
  • Height (mm) : 336*
  • Weight (g): approx. 1250

*it depends to the final design of the nosepiece
