Turning balls, especially in safety-<\/span>critical<\/span> areas such as the automotive industry, <\/span>places<\/span> the highest demands on precision, <\/span>repeatability<\/span> and cycle time. Components such as ball pins in ball joints play <\/span>a central role<\/span> in steering and chassis. Their production requires <\/span>state-of-the-art<\/span> turning technology – especially when it comes to <\/span>large quantities<\/span> and economical processes.<\/span><\/span>\u00a0<\/span><\/strong><\/p>\n

Technical requirements for ball turning<\/h3>\n

Ball turning is a special process in machining technology in which not only an exact ball shape but also a uniform, high-precision surface must be produced. This is necessary to ensure smooth movement in the joint and prevent premature wear. Depending on the size of the component, ball diameters between 16 and 40 mm with tolerances in the micrometre range must be achieved.<\/span>\u00a0<\/span><\/p>\n

Challenges in batch production<\/h3>\n

In large-scale production, the challenge is to combine this precision with short cycle times. A reliable solution must not only offer high repeatability and process reliability, but also minimize tool wear and be easy to automate. <\/span>In addition, all quality requirements must be verifiable inline.<\/span>\u00a0<\/span><\/p>\n
