For accurate measurement of camshafts, our go-to machine is the Hommel Contour. This is a non-contact measurement system for diameter, length, geometry, form and position.
The Hommel can measure pieces up to 850mm long and up to 20kg in weight with an accuracy of < 2µm
From a single press of a button, the Hommel will measure all aspects of the component wear on other associated parts and produce an extensive drawing.
This machine is invaluable in performing analysis on sample products, developing new part numbers and ensuring first-off parts conform to drawing.
One of our most frequently used machines is the Zwick Roell Rockwell Hardness Tester. Hardness is a critical property of many valvetrain components such as Camshafts and Rocker Arms. If the part is not hard enough it will wear prematurely and this could lead to it failing or increasing wear on other associated parts. Generally, a failure in the valvetrain leads to extensive engine damage often necessitating a full rebuild.
The Rockwell scale is based on indentation hardness of a material. The tester applies a pre-determined force to an indenter, typically a small diamond or steel sphere, into the material to be tested. The depth of the resulting indentation is used to calculate the hardness. This process allows Eurocams to accurately control the hardness of any incoming product.
To measure other components, our Smartscope Flash 200 is invaluable. This CMM (Co-ordinate Measuring Machine) can use a multitude of different methods to ensure our products fully confirm to our specifications.
The Flash is a fully automatic measurement system, which measures up to 200 x 200 x 150mm XYZ travel. It can use a combination of camera, touch probe, laser and scanning probes to build a complete picture of the relevant part.
Finally, we have our Hydraulic Lifter Test Machine. This machine was manufactured to our specifications. We use it to check hydraulic lifters for the correct level of leakdown which is crucial to the function of the lifter.
If the leakdown rate is too high, the lifter will allow ‘lash’ in the valvetrain, creating excess noise and reducing the life of the associated components. Too low and the shock-absorbing effect of the lifter will be reduced leading to damage to the camshaft or valve stem.
