 Transfer machines

   

 
We are specialized in transfer machines, which test and perform assembly operations on cylinder blocks and cylinder heads. Our key capabilities are testing and assembly operations within the machining line (pre-assemblies).
Specifically, these include the following operations:

Leak test
Water jacket, oil galleries, crank case cavity, air tracts, intake ports, spark-plug domes

Flow test
Complex oil galleries are flow tested for proper cross sections

Gauging

  • Diameter and form error of cylinder bores, including grading into classes
  • Crankshaft and camshaft bearing bores
  • Valve seat and valve guide bores
  • Counter bores for lip seal rings
  • Cylinder liners

Assembly

  • Cup plugs with application of sealer to the core hole
  • Screw plugs and sealing balls
  • Bearing caps and bedplates with preceeding dowel assembly
  • Valve seats and valve guides with and without cold shrinking with liquid nitrogen
