1. what is a four-axis machining center

The four-axis machining center refers to the machining center corresponding to the fourth axis of the CNC machine tool.

In the three-axis CNC machining center, a rotating axis is added, usually called the fourth axis.

Machining center is mainly used for processing plane, groove, curved surface, is the fastest growing products in CNC machine tools, is also the most widely used machine tools, machining center for machining, mold, shipbuilding industry, automotive and parts, aerospace and other fields.

Features of 2. four-axis machining center

(1) Four-axis machining programming is complex and difficult.

Because multi-axis machining is different from the three-axis, it is in addition to the three linear motion, there are 1 to 2 rotational motion involved, the formation of the synthetic motion of the spatial trajectory is very complex and abstract, generally difficult to imagine and understand.

For example, in order to process the required space free-form surface, it is often necessary to use multiple coordinate transformations or complex tool axis pointing control methods, and at the same time consider the coordination of the movement of each axis to avoid interference and collision.

Four-axis machining can improve production efficiency.

Multi-axis CNC machining can simultaneously control the linkage of more than 4 coordinate axes, and combine the functions of CNC milling, CNC boring, CNC drilling, etc. After the workpiece is clamped at one time, the machining surface can be milled, bored, drilled and other multi-process processing, effectively avoiding the positioning error caused by multiple installations, shortening the production cycle and improving the machining accuracy.

3. The four-axis CNC machining center has the characteristics of high precision.

In the process of four-axis machining, the workpiece can complete the processing of multiple surfaces after one clamping, and can also perform high-precision machining of complex spatial surfaces. Very suitable for processing auto parts, aircraft structural parts and other parts of the forming mold.

3. compared to three-axis machining four-axis advantages

Disadvantages of three axis machining:

1. The tool length is too long, the tool cost is too high

2. Tool vibration leads to roughness problem

3. Process increase, multiple clamping

4. The tool is easy to break

5. Increased number of tools

6. Unqualified workpieces caused by over-cutting

7. Repeat the knife to produce cumulative tolerances.

Four-axis advantages:

1. The tool has been greatly improved

2. The processing process shortens the clamping time

3. No fixture required

4. Improve surface quality

5. Extend tool life

6. Centralization of production

7. Effectively improve processing efficiency and production efficiency.

Main Application Fields and Typical Parts of 4. Four-axis Machining

Main fields: aviation, shipbuilding, medicine, automobile industry, mold.

Typical parts: cam, turbine, worm, propeller, shoe mold, mannequin, auto parts, other precision parts processing.
