The invention discloses an automatic 
machining production device for an automobile 
brake component and a working method thereof. The production device comprises a transversely-arranged 
robot travelling ground rail, a first grabbing mechanism, a plurality of 
numerical control grinding machine tools, a feeding conveying belt, an automobile 
brake component overturning table, a second grabbing mechanism, a transfer conveying belt, a pneumatic 
scrap clearing table, a control center, two drilling and tapping 
numerical control machine tools, a 
cutting fluid filtering disc, a weighing disc, a coding 
machine, a first qualified product discharging conveying belt, an unqualified product discharging conveying belt, a sampling inspection circulating table, a detection analysis table, a manual 
processing device and a second qualified product discharging conveying belt. The first grabbing mechanism grabs the automobile 
brake component to be ground in the 
numerical control grinding machine tools, and the second grabbing mechanism grabs the automobile brake component to be subjected to drilling, tapping and other operations, so that the technical problems that in the prior art, the automobile brake component 
machining efficiency is low, the labor intensity of workers is too large, industrial accidents frequently happen, and the product percent of pass is low are solved.
