Hommel-Etamic France, S.A., Sucursal en España (Jenoptik) - Measurement instruments (durometer, callipers, profilometers, etc.)

The manufacture of trees of levy and of crankshafts has to effect with precision to be able to obtain groups motors of high qualitative quality and accionamientos of saving of promising power. To fulfil with some tolerances and some requirements of quality increasingly demanding for the manufacture of trees of levy and crankshafts, Hommel-Etamic has followed optimising his systems of measurement CFM has created, with Shaftscan 1030, a system of measurement of high precision.

Hommel-Etamic Follows a different principle without compensation laser, employing a unit guides linear of high precision with cojinetes of air in combination with an accionamiento by wire without vibration. With this system of measurement without holguras neither tension of investment, the strengths of mechanical shearing do not influence in the result of the measurement. Another advantage: the system of measurement does not see affected by the changes of temperature, the environingingmental humidity or the atmospheric pressesure. Thanks to a blade of measurement with a wand of hard metal that the user can turn after the wear and calibrate through a menu, hardly arise costs of maintenance.

During the rectification of the trees of levy and of the crankshafts can appear the calls mark of retemblado, that cause annoying noises in the engine even with some relatively small amplitudes. For palpar these ondulaciones very frequent, only can apply a system of measurement that fulfil the following requirements: a cabezal of measurement without swing with a good circular movement, a high density of the points of measurement, as well as a palpation of the ondulación of the surface without game of investment owing to amplitudes reduced. Besides, it has to offer the possibility to realise an analysis FFT for the assessment of the surface. With a tax of register of values of measurement of 3.600 points of measurement by each 360°, a precision of movement circulate of the rolling of 0,3 µm and repetibilidad of until 0,2 µm, Hommel-Etamic Shaftscan 1030 offers reproducible results of upper waves and of amplitudes.
