Faced with the common "three-axis", "four-axis", and "five-axis" machining services in the market, many users have questions about their technical differences and cost distinctions. This article will delve into the characteristics of machine tools with different numbers of axes, assisting you in accurately matching your project requirements.

1. Three-axis CNC machining

1. Operating mechanism

A three-axis machine tool completes cutting by moving the tool in three linear directions:

X-axis: Horizontal left-right movement

Y-axis: back-and-forth motion

Z-axis: vertical lifting operation

The workpiece is fixed on the workbench throughout the entire process, and the machining of the top and sides of the object is achieved through the three-dimensional motion of the cutting tool.

2. Core advantages

Outstanding cost-effectiveness: minimal equipment investment and maintenance costs

Technology popularization: programming is simple, and there is an abundant reserve of technical talents

Wide adaptability: suitable for plate and disc parts as well as simple 3D contour machining

3. Technical limitations

Multi-face machining requires multiple clamping operations, which can easily affect the accuracy

It is difficult to deal with complex surface machining in aerospace, automotive molds and other fields

4. Typical application scenarios

Metal plate processing

Basic mold manufacturing

Connecting rod and bearing seat

Architectural sand table model

II. Four-axis CNC machining

1. Technical principle

Based on the traditional three-axis system, an A-axis that rotates around the X-axis is added, allowing the workpiece to rotate 360° along with the worktable, enabling multi-sided machining with a single setup.

2. Significant advantages

The number of clamping operations has been reduced by more than 50%, resulting in a significant improvement in accuracy

It is particularly suitable for circumferential engraving of cylindrical parts

Achieve the optimal balance between complexity and cost

3. Applicable boundaries

There are still processing limitations for parts with special spatial geometric structures

Innovative application areas

Engine housing machining

Carving of sound holes for wind instruments

Cylindrical relief creation

Multi-face machining of frame structural components

III. Five-axis CNC machining

1. Technological breakthrough

Based on three-dimensional linear motion, the A-axis (rotation around the X-axis) and C-axis (rotation around the Z-axis) are synchronously integrated to enable the tool to approach the workpiece from any angle, allowing for the machining of a pentahedron with a single setup.

Outstanding characteristics

Overcome the challenges of machining complex spatial surfaces

Prevent the accumulation of errors caused by multiple clamping

Obtain optimal surface treatment effects through dynamic tool posture adjustment

Support high-speed cutting technology, with efficiency increased by over 40%

2. Application threshold

The equipment investment and programming cost are the highest

A team of professional engineers is required

Cutting-edge application scenarios

Aeroengine blade

Automotive panel mold

Medical artificial joint

Large-scale art sculpture

Ship propeller
