In order to extend the life of the die, the hardness of the machined material is also increasing. Therefore, higher requirements are put forward for the tool life and machining efficiency in the high-speed machining of the hardened material. In a typical environment, we could have a micro ball nose end mills selection from three points:

1. Choose the type of tool coating according to the type and hardness of the workpiece. Miracle coating can be used for workpieces with HRC50 hardness such as alloy steel S and tool steel. The tool shape, hard alloy material, and coating can be selected when machining the workpiece with higher hardness. Miracle coating is used for machining the high hardness material.

2. Choose a micro ball nose end millsprofile based on the shape of the workpiece. Micro ball nose end mills cutter neck shape is divided into scale, long neck, and cone neck, according to the depth of processing and shape of the workpiece to choose. The long neck type and the cone neck type may carry on the deep excavation processing, should consider the interference angle when choosing both. At the same time, compared with the long neck type, the cone neck type micro ball nose end mills have higher rigidity, can improve cutting conditions, and achieve better machining accuracy, should just choose the cone neck type micro ball nose end mills.

3. Choose micro ball nose end mills with different ball head precision according to machining accuracy. The arc precision of micro ball nose end mills is usually ± 10μm, but there are also ± 5μm high precision micro ball nose end mills, which can be used in high precision machining.
