Análise de desgaste em fuso de esferas de retíficas

Abstract

The present study analyzes wear in ball screw from grinding machines, which are essential for precision in the manufacturing of diesel injector nozzles. Given the need for precision in the assembly, it is important to identify the critical wear points in ball screws and nuts to understand how each type of wear contributes to assembly failure and to guide appropriate mitigation solutions. The wear analysis methodology included: visual inspection, sectioning for macroscopic, microscopic analyses, scanning electron microscopy (SEM) and X-ray spectroscopy. The results indicate that the main types of wear are abrasion, deformation adhesion and the worst damage are observed in the ball screws compared to the nuts.
