------------------------------------------------------------
Crank shaft
Efficient measurement systems and evaluation software from HOMMEL-ETAMIC solve almost every measuring task on the crank shaft. This is considered the heart of the classic piston engine and must guarantee high power transmission, smooth running and long life at the same time as low weight. The quality requirements and demands on the metrology are therefore accordingly high.
-------------------------------------------------------------
Cam shaft
For forged or assembled cam shafts, HOMMEL-ETAMIC offers the right measuring solution for monitoring the production quality. Sophisticated technical solutions are required especially for measuring the cam form, the cam angle, the surface nature and detecting chattermarks.
----------------------------------------------------------
Cylinder block
On the cylinder block component, the form of the cylinder bore under the influence of temperature plays an important role in guaranteeing performance, smooth running and consumption. Another important characteristic is the surface nature of the cylinder liner for ensuring the life of the engine. The sealing surfaces may not exhibit any dominant waviness so that permanent tightness is guaranteed. We offer the right measuring solution for these function-oriented characteristics.

Cylinder head
Complex combustion chamber geometries with very precise valve guides and optimised geometries for the valve seats ensure a trouble-free gas change together with the valves. Owing to the high complexity of this component, a large number of characteristics needs to be checked by measurements to assure the quality. With the possibility of fully automating complex measurement runs, the HOMMEL-ETAMIC measurement systems offer optimum economical solutions which are distinguished by easy operation and high precision.
---------------------------------------------------------------
Valve
Valves are manufactured in production lines in short cycle times, large quantities and wide variety. A uniformly high quality with regard to the dimensional stability and surface quality is necessary. Supplementary to the tactile measurement principles we supply flexible, efficient solutions based on optical metrology - to exactly suit your requirements.
-------------------------------------------------------------
Piston
Pistons are subjected to high pressure and temperature loads. Optimised outer form geometries ensure a consistently good function under all operating conditions. Prerequisite for this is that the narrow tolerances are kept for the complex outer form. Just as relevant to the function is the position of the piston bolt bore and the dimensional stability of the piston grooves. HOMMEL-ETAMIC offers solutions specially for this component which measure and evaluate these complex characteristics with maximum precision.
-------------------------------------------------------------
Con rod
Relevant for measurements on the con rod are the diameter and the form and position tolerances of the con rod eyes and the distance between the con rod eyes. Narrower tolerances provide a more accurate fit of the bearings. Special geometries such as the trumpet shape optimise the bearing capacity between the con rod and the connecting bolts.
Our production-integrated measuring machines can classify the con rods according to the criteria of weight, diameter and con rod eye distance with applied creation of pairs on request.
