            • rectificació Operació d'acabament a la qual són sotmeses les peces mecanitzades, especialment les que han estat trempades i tenen una tolerància acceptada molt baixa, per tal de corregir definitivament les irregularitats de caràcter geomètric de llurs superfícies, tant si són planes com si són cilíndriques o còniques, tant si són interiors com exteriors, acanalades, roscades, etc, per l'acció d'una mola damunt d'elles. Aquesta operació és efectuada en les màquines anomenades rectificadores. Amb la rectificació, hom pot obtenir acabaments de peces amb una tolerància compresa entre un centèsim i un mil·lèsim de mil·límetre. Enciclopèdia Catalana - by Núria Bonet

          • Definition(s)
            • A process to correct the concentricity and shape of a grinding wheel. As distinguished from dressing, which removes bond material to expose fresh abrasive grains, truing is designed to reduce vibration and produce a uniform cutting rate for the grinding wheel. Abrasive Engineering Society
          • Example sentence(s)
            • Truing and grinding forces and the wear mechanism of particle and rod diamond blade tools used to generate precise and intricate forms on rotating vitreous bond silicon carbide grinding wheels are presented. - Science direct
            • Once a major stumbling block to the efficient use of superabrasive production wheels, truing and dressing have come of age with the introduction of new tools, techniques and methods, including modular devices that automate the processes. - bnet
            • Manufacturers have found rotary dressing and truing to be superior to single point, cluster and stick dressing for processes that require high part production and/or close part tolerances. - G II Solutions, Inc
