What are the processing types of end mills?

End mill processing types include: plane milling, side milling, slot milling, profile milling, and step milling. End mills are commonly used multi-purpose tools in CNC machining, suitable for various metal cutting scenarios.

I. End Mill Processing Types and Characteristics:

1. Plane Milling (Face Milling)

Purpose : Processing the horizontal or inclined planes of workpieces, such as surface leveling and rough machining.

Characteristics : Using the end face to quickly remove material, suitable for large-area high-efficiency cutting.

Tool Selection : Flat end mill (four-blade or two-blade).

2. Side Milling

Purpose : Processing vertical or inclined side walls, cavities, steps, etc.

Characteristics : Precise cutting is performed using the side edge, with high requirements for tool rigidity and precision.

Tool Selection : Long-edged end mill or carbide-coated tool.

3. Slot Milling (Keyway Processing) / : Milling closed or open grooves (such as keyways,

Purpose T -shaped grooves). : The tool needs good chip removal ability and vibration resistance to avoid tool breakage.

Characteristics : Narrow-blade end mill or special slot milling cutter.

Tool Selection Profile Milling (Curved Surface Processing)

4. : Processing complex curved surfaces, mold cavities, and irregular contours. 3D : Requires multi-axis linkage, and the tool needs to balance precision and surface finish.

Purpose : Ball end mill or round nose end mill (with

Characteristics R

Tool Selection angle). Step Milling (Layer Milling) : Layer-by-layer cutting of deep grooves or high side walls to avoid tool overload.

5. : Layer-by-layer processing, controlling the cutting depth, suitable for difficult-to-process materials (such as stainless steel).

Purpose : High-rigidity carbide end mill.
