Shanghai ANTISHICNC Company has successfully applied CNC lathe technology to the production of SKD11 brake bushings, achieving high-precision and high-efficiency processing, and bringing new breakthroughs to the large-scale production of key components of automotive brake systems.
SKD11 is a high-carbon, high-chromium alloy tool steel with excellent wear resistance, toughness and heat treatment dimensional stability. It is widely used in motorcycles, automotive brake bushings and other core brake parts. However, its high hardness characteristics pose a severe challenge to the processing technology. Traditional processing methods are prone to problems such as insufficient precision and low production efficiency. Shanghai ANTISHICNC Company uses the CK0640 fully automated CNC lathe machine with 0.01mm cutting accuracy and intelligent programming system. It can automatically optimize cutting parameters according to the material characteristics of SKD11, while ensuring that the cylindrical error of the bushing is controlled at ±0.005mm, and shorten the single-piece processing cycle by 40%.
The application of the CK0640 fully automated CNC lathe machine solves the two major pain points of SKD11 material brake bushing turning: surface roughness and dimensional consistency. The lathe can drive the spindle and tool holder of the lathe through the servo motor according to the preset program when the workpiece rotates at high speed, and accurately control the feed speed, rotation angle and cutting depth of the tool. It can complete the seamless connection of multiple processes such as inner hole boring, outer circle turning, and thread processing. The whole process does not require frequent manual intervention, effectively avoiding human errors. Through the combination of precision grinding and high-speed milling technology, the surface roughness of the inner wall of the bushing can reach Ra0.8μm, which perfectly meets the dual requirements of the automobile braking system for sealing and wear resistance.
As a key guarantee for automobile safety performance, the machining accuracy of the brake bushing directly affects the braking response speed and service life. The CK0640 fully automated CNC lathe not only opens up an efficient production path for SKD11 material parts, but also promotes the transformation of automobile parts manufacturing from “experience-driven” to “data-driven”. In the future, with the continuous iteration of intelligent manufacturing technology, it is expected that more high-performance metal materials will be industrialized in the field of CNC turning, helping my country’s automobile industry to move towards high-end development.
