What are the advantages and applications of five-axis CNC machining and milling machines

Before the advent of five-axis CNC machining and milling technology, everyone used traditional three-axis CNC machining. With the development of the times, five-axis CNC machining and milling has gradually replaced three-axis CNC machining and milling as the mainstream. Below, we will take you through our VMT to walk you through the advantages of the next generation of 5-axis CNC machining milling centers.

The traditional three-axis CNC machining equipment does not have the ability to process arbitrarily complex surfaces. Complex workpieces generally need to be processed in blocks, and the CNC machining of complex workpieces and complex processes takes a long time and requires the cooperation of multiple equipment and multiple people.

It has obvious shortcomings. The emergence of five-axis CNC machining and milling technology provides a good solution for the rapid CNC machining of any complex surface workpiece.

Five-axis simultaneous CNC machining and milling technology uses three linear motions and two rotational parallel motions to complete CNC machining of any spatial surface. One-time clamping, multi-sided automatic processing, one-time forming of complex surfaces, and tight integration. It has the advantages of CAD/CAM/CAPP, etc., and is a reliable guarantee for the CNC machining cycle and CNC machining quality.

The working principle of five-axis CNC milling

Five-axis CNC machining and milling means that there are at least five coordinate axes (three linear coordinates and two rotational coordinates) on the machine tool, and under the control of a computer numerical control (CNC) system, coordinates and machining can be performed simultaneously. time

Linearly interpolate movement using any 5 coordinates between X, Y, Z, A, B and C. Machine tools used for five-axis machining are often referred to as five-axis machines or five-axis CNC machining milling centers.

Advantages of five-axis CNC machining and milling machines

1) Five-axis CNC machining and milling can effectively avoid tool processing, and three-axis CNC machining of complex parts that are difficult to process with milling cutters;

2) CNC machining of ruled surface adopts side milling for one-time forming, which has high processing quality and high processing efficiency;

3) Five-axis CNC machining and milling can realize one-time clamping, multi-face, multi-process CNC machining, which is easy to ensure product accuracy;

4) In the five-axis CNC machining and milling, the tool has a good cutting state relative to the workpiece;

5) For channel NC machining and compound surface transition zone machining with limited NC machining space, a larger size tool can be selected for five-axis NC machining and milling to avoid machining interference and have good tool stiffness.

Five-axis CNC machining and milling applications

The five-axis CNC machining and milling center is suitable for complex, multi-process and high-precision requirements. It requires multiple types of common machine tools and multiple tools and fixtures. After many times of clamping and adjustment, the CNC machining of the corresponding batch of five-axis CNC machining milling parts can be completed.

1. Five-axis CNC machining and milling center and box parts

Box parts are parts with multiple holes and multiple cavities. There are many parts in the machinery, automobile, aircraft and other industries, such as body knowledge, gasoline, car toy boxes, diesel generators, tire pumps, etc.

2. Five-axis CNC machining and milling center and complex surfaces

In the fields of aerospace, automobile, ship, national defense and other products, complex curved surfaces occupy a large proportion, such as impellers, propellers, various surface forming molds, etc.

3. Five-axis CNC machining and milling machine to process special-shaped parts

Special-shaped parts are CNC machined parts with irregular shapes, most of which require multi-station mixed machining of points, lines and surfaces, such as brackets, bases, templates and profiling.

The rigidity of special-shaped parts is generally poor, the clamping pressure and cutting deformation are difficult to control, and the machining accuracy is difficult to guarantee. At this time, you can make full use of the processing characteristics of the five-axis CNC machining and milling center, reasonable process measures, one or two clamping, and complete multi-process or all CNC machining content.

4.5-axis CNC machining milling center for milling discs, sleeves and sheets

Disc sleeves or shaft parts with keyways, radial holes or distributed holes on the ends and curved surfaces, as well as plate parts with a large number of holes, are suitable for five-axis CNC machining and milling machine processing.

Parts with distributed holes and curved surfaces on the end face should use a vertical five-axis CNC machining and milling center, or a horizontal machining center with radial holes.

Summarize

Five-axis simultaneous CNC machining and milling has higher precision than traditional three-axis simultaneous CNC machining and milling, which solves the problem that three-axis simultaneous CNC machining cannot process complex surfaces and is time-consuming and labor-intensive. The working cycle and the quality of CNC machined parts are reliably guaranteed.
