Starting from real shop-floor pain points, this article breaks down the core technologies behind automated motor housing deburring. We cover process comparisons (manual vs. robotic), the application of active force control technology, process flow breakdown, and consumable cost control. Through detailed technical data and actual production cases, we demonstrate the economic benefits of automated grinding solutions, helping you solve flash challenges and achieve optimal balance between quality and efficiency.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">O que \u00e9 um compartimento de motor fundido?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A carca\u00e7a do motor fundida em alum\u00ednio \u00e9 um componente essencial do trem de for\u00e7a dos ve\u00edculos de energia nova (NEVs).
