Abstract:
Precision machining is a fundamental element and, in particular, due to its high level of performance, parts and tools can be produced for several types of industry such as automotive, aerospace and military, for instance.
Technological advancement succeeds in a systematic and robust way, bringing greater efficiency and reliability in precision machining, besides making the work more productive and safer.
Therefore, precision machining is the machining process state of the art, which is currently capable of producing a great variety of high complexity and perfection products. This is possible because of the computerized control of its various functions.
Among the severals components capable of entrusting the machining such responsibility, the grinding wheel stands out with great and significant importance in the parameters of geometry and surface quality of the rolls, according to the needs of the rolling mill.
The type of grinding wheel, the rolls materials and the required parameters adjustment, have an important influence on the behavior of the Flat Steel Rolling Mills rolls, as well as on the specific effective consumption of the mill rolls.
This work aims at presenting the results of the development of a new grinding wheel, as well as demonstrating the gains obtained by the grinding of rolls in Gerdau Flat Steel rolling mills with better performance of geometric parameters, surface quality, cost reduction besides greater safety together with the decreasing of people exposure during a grinding wheel changing activity
