Milling machining

Milling Machining

Milling machining is an efficient method that uses a rotating tool (milling cutting) to remove material from the workpiece surface. In this process, the workpiece is fixed on a fixture while the milling cutting rotates at high speed and moves along the workpiece to achieve the desired shape and size.

Introduction of CNC Milling Machines Axial Concept
In the milling machine process, the axial direction refers to the direction the tool or workpiece can move. Standard axial directions include:

X axis:

Horizontal direction (left and right).

Y axis:

Horizontal direction (front and back).

Z axis:

Vertical direction (up and down).

A axis:

Rotation around the X axis.

B axis:

Rotation around the Y axis.

C axis:

Rotation around the Z axis.

Different Types of Milling Machining Processes

Three-axis Milling Machining

The three-axis milling machine is one of the most basic milling machines, with the ability to move in three axes: X, Y, and Z. This machining method is suitable for processing simple flat and curved surfaces, such as flat milling, solid milling, drilling, and tapping. Key features include:

Machining range:

It is usually used for two-dimensional surface machining and is suitable for machining basic shapes such as flats, grooves, holes, etc.

Accuracy:

It can achieve high-precision machining and is suitable for parts with high surface requirements.

Application:

It's widely used in machining, mould manufacturing, workshop production, and other fields.

Four-axis Milling Machining

The four-axis milling machine adds a rotary axis (usually the A-axis or C-axis) to the three-axis, allowing the workpiece to rotate around the rotary axis while the tool moves along the X, Y, and Z axes. This configuration enables machining on multiple sides of a workpiece without re-clamping the parts, thus improving machining efficiency and accuracy. It is suitable for machining workpieces with rotating features such as cams, crankshafts, and spiral grooves.

Four-point-five-axis Milling Machining

A four-point five-axis milling machine is between four-axis and five-axis, which usually means that, based on three axes, the rotation angle of the rotating axis (such as the A-axis or C-axis) is limited, rather than a full 360-degree rotation. Nevertheless, it can still provide more flexible processing capabilities in some specific applications than the 3-axis, such as tilt processing at a certain angle or rotation processing.

Fix axis Milling Machining

A five-axis milling machine is one of the most advanced milling technologies, and it can move in five axes: X, Y, Z, A, and B (or C). The tool and part can move in multiple axes at the same time to achieve complex spatial surface machining. This technology can significantly reduce operation times, improve machining accuracy and efficiency, and machine complex shapes that are difficult to reach with traditional machining. Suitable for industries with high precision requirements, such as aerospace, moulds, medical devices, etc., such as turbine blades, complex moulds, and artificial joints.
