Especially its semispherical or arc-shaped blade part. This shape makes it difficult for coolant to evenly cover the entire cutting area. This leads to local high temperature, accelerating tool wear and damage, and the cutting area of ball milling cutter is usually narrow when machining complex curved surface, especially when machining deep groove or enclosed space. This narrow space limits the flow of coolant, making it difficult for coolant to reach the cutting point, resulting in poor heat dissipation.
