Ball Screw Whirling, 76% Tool Life Extended

Rolling Functional Components Industry

• High precision requirements: Strict demands on dimensional accuracy, geometric tolerances, and surface quality made conventional machining processes complex.
• Rapid tool wear: High ball screw hardness led to accelerated insert wear.
• Low machining efficiency: Frequent tool changes increased costs and reduced productivity.

High-precision CNC whirling machines combined with customized PCBN whirling tools were adopted for dry cutting, significantly extending tool life.

• Tool life: Increased by 76%, extending machining life from 50 to 90 workpieces.
• Production efficiency: Increased by 130%, with faster cutting speeds and fewer tool changes.
• Machining cost: Tool usage cost reduced by 60%.
• Customer feedback: “The new machining solution greatly reduced our tool selection and tool change frequency. It has significantly extended the tool life, substantially reduced machining costs, and ensured production capacity.”
