LAMECO Laminated Shims - LAMECO - #1

Any mechanical assembly requires machining tolerances. In a complex assembly of several hundred or thousand parts, the tolerances of each part are added up. This is why " clearances " of several millimeters are found once the assembly is completed. These clearances have to be compensated in order for the assembly to fulfill its function.Before the laminated shims were invented technicians could only resort to two methods - which today are obsolete - to suppress the clearance observed in an assembly :

Principle : after measuring the clearance to be compensated the technician submits thickness parts to a grinding operation. These accessories are named adjustment shims. He thus gives them a precise dimension, set out as a function of the measured clearance.

Disadvantage : this process is long and costly. It requires the purchase of a grinding machine and implies a lasting outage of the assembly line.

Principle : technicians pile up metal sheets which they insert into the accessible places.

Disandvantage : this method brings about a dangerous imprecision. Due to residual matters, dusts, grease and other chips which get in during any piling up, the achieved result remains very uncertain.
