الشق

Slotting is one of the most common applications. An end mill cutter can cut straight or curved slots into a workpiece with good accuracy. These slots can create keyways, الأخاديد, guide tracks, and assembly features.

For softer materials such as aluminum, chip evacuation is important. Therefore, machinists often select 2 flute tools when the workpiece needs better chip removal.

الطحن الجانبي

Side milling uses the side cutting edges of the tool to remove material from the vertical surface of a workpiece. This operation is useful for machining shoulders, steps, and side walls.

Machine shops commonly use side milling for precision parts, مكونات القالب, tooling parts, and general CNC production.

Profiling and Contouring

Machinists also use end mill cutters for profiling and contouring. These operations create complex shapes, curved paths, and external or internal profiles.

Machinists often select ball nose and corner radius tools for this kind of work because these tools can improve surface transitions and finishing quality.

طحن الجيب

Pocket milling removes material from a closed or recessed area inside a workpiece. This operation is common in parts that need internal cavities, weight reduction, or precise material removal within a limited area.

Good chip control, stable tool paths, and the correct cutter geometry are important for this process.

التشطيب السطحي

After rough machining, an end mill cutter can also be used for finishing. The goal is to improve dimensional accuracy and surface smoothness.

Finishing tools are selected according to tolerance, مادة الشغل, machine stability, and required surface quality.

Step Milling and Shoulder Machining
