Nut Raceway Turning, 150% Efficiency Increased

Rolling Functional Components Industry

• High raceway precision requirements: Strict demands on raceway profile accuracy and surface roughness.
• High workpiece hardness: Cutting force fluctuations during turning caused cutting edge chipping.
• Low machining efficiency: The original solution had low cutting efficiency, with time-consuming tool changes and setup adjustments.

A precision turning machine equipped with customized PCBN form tools was used to perform single-pass high-speed form cutting.

• Tool life: PCBN tool life was 16 times longer than that of carbide tools.
• Machining cost: Reduced by shortening machining time per part and reducing tool change frequency by 60%.
• Production efficiency: Increased by 150%, with single-pass high-speed form cutting significantly improving productivity.
• Customer feedback: “The new raceway cutting solution simplifies the process while doubling the raceway machining pass rate, it significantly improves production efficiency.”
