With the Easy-Laser® Linebore system you measure straightness of cam and crankshaft
bearing journals, with a resolution of 0.001 mm [0.05 mils] and a maximum
distance of 40 m [132 feet]. Both open and closed journals can be measured,
as well as journals with different diameters. Regardless of the engine design,
the measurement is done very fast.
Measuring the position of the journals
The laser transmitter is mounted (with magnets) axially at the end of the engine.
With its built-in offset hub the direction of the laser beam is easily fine
adjusted. Then the detector is placed in the journals and values are recorded
in each. The result of the measurement displays the position of the journals
in vertical and horizontal direction, compared to two zero points (references).
These can be any two of the journals, and can be altered to calculate minimum
tooling work. The result is displayed both digitally and graphically, and can be
transferred to a PC for documentation or further analyse.
Other applications for engine manufacurers
Other applications for engine manufacurers are for example flatness on parting
surfaces, squareness for cylinder bores, shaft alignment when mounting the drive
line.
