Why AMG D6R3 Ball Nose End Mill Is Ideal for Semi Finishing and Finishing in Precision Machining

2025-08-04

In the CNC machining industry, many customers may see the terms "semi precision machining" and "precision machining" when purchasing ball end mills, but the specific differences are not always clear. In response to this common issue, the AMG technical team recently provided a detailed explanation of the application positioning of their D6R3 ball cutter.


It is reported that semi precision machining refers to a transitional stage after rough machining and before precision machining, with the aim of gradually approaching the final shape of the workpiece surface contour while leaving very little margin for subsequent precision machining to achieve ideal size and surface quality. Precision machining is the final dimensional adjustment and surface improvement of products, requiring tools to have higher geometric accuracy, cutting stability, and excellent smoothness performance.


The AMG D6R3 ball cutter adopts an R3 ball head radius design, which balances cutting coverage and surface following ability, making it particularly suitable for 3D surface processing scenarios with high smoothness requirements such as mold cavities and medical contours. In the semi precision and precision machining stages, its low vibration, smooth cutting, and excellent wear resistance make it an indispensable core tool in efficient machining. This product has been widely used in industries such as automotive, medical, and mold manufacturing, with a stable surface roughness controlled between Ra0.4~0.8 μ m.
