In the production of high precision matching components like injectors, injection cocks and pumps, it’s extremely important to guarantee the smallest shape errors on the machined workpieces. The cylindricity tolerance on these parts is typically tight, and their inspection can be generally performed only with Metrology Lab instruments. The use of “M39S Scanning System” generally allows to detect, directly in the shop floor environment, all the shape errors related to the measurement of diameter and its variation along the axis of the part (like taper and barrel shape).
