Manufacturing Process and Equipment Design of Automotive Brake Calipers
Abstract：Brake caliper, as a part of the auto brake assembly system, has a very important role,
its quality directly affects the ability to provide a effective braking force on the car at high speed when the driver stepping on the brakes, belonging to the key part. With disc brakes are increasingly widespread used by cars and light trucks,the manufacturing process and the equipment of the brake caliper body is also much attention. In this thesis, automotive brake caliper for the study, by analyzing the working principle, production and processing
requirements of parts , such as mass, dimensional accuracy, shape and position accuracy, heat treatment ,etc. Meanwhile lookup and calculation blank margin, margin of each processing step, cutting, etc. To determine the solution of the rough casting, blank dimensions, and parts of the machining process route. Ultimately determine the machining process solutions and special tools, special fixture design, complete CNC program preparation.
