1. Use ground blades as far as possible for fine milling
The grinding blade has good dimensional accuracy and high positioning accuracy, so better machining accuracy and surface roughness can be obtained during processing. The large positive cutting edge of the thread mill allows the insert to cut at small feeds and depths of cut. Without sharp rake angle carbide inserts, the tool life will be severely damaged when deep machining at small feeds is performed.

2. In some processing occasions, pressing blades are used
Rough machining requires the use of pressed inserts, which can reduce machining costs. The dimensional accuracy and edge sharpness of the pressed blade are worse than those of the ground blade, but the edge strength of the pressed blade is better, and it is resistant to impact during rough machining and can withstand a large depth of cut and feed. The pressed inserts sometimes have chip grooves on the rake face, which can reduce the cutting force, and at the same time, reduce the friction with the workpiece and chips, and reduce the power demand.
Ground high rake angle inserts for milling sticky materials. Through the shearing action of the sharp edge, the friction between the blade and the workpiece material is reduced, and the chips can leave the front of the blade faster.
