4 axis cnc machining center

4 Axis CNC Machining Center Introduction

Generally, when the workpiece has not been positioned in space, there are six degrees of freedom processing range, three linear displacement degrees of freedom X, Y, Z and three rotational displacement degrees of freedom A, B, and C corresponding to the processed parts.

The three-axis machining center machine tool runs through the three linear axes of X, Y, and Z, and processes the parts that need to be processed respectively. 4 axis cnc machining center is to add a very important A rotation axis on the basis of three axes.

The 4 axis cnc machining center has four displacement degrees of freedom, X, Y, Z, and A, so that different objects can be processed with high precision. 4 axis cnc machining center can adapt to various parts processing.

The 4 axis cnc machining center can be adapted to parts processing in the mold industry, auto parts and wheel processing, automatic machining, and is also widely used in aerospace and other fields.

Features of 4 Axis CNC Machining Center:

1. The programming is complex and difficult.
2. 4 axis cnc machining center can improve production efficiency.
3. The 4 axis cnc machining center has the characteristics of high precision.

Advantages of 4 Axis CNC Machining Center：

(1) Strong adaptability

The 4 axis cnc machining center is suitable for processing single or small batches of complex workpieces. CNC machine tools can process many parts with complex surfaces that are difficult or impossible to process with ordinary machine tools. High-speed CNC engraving and milling machines are such as propellers.

The 4 axis cnc machining center has the function of multi-axis linkage, and the tool can move according to the space curve trajectory. Therefore, the 4 axis cnc machining center was first used in aerospace and other fields, and it has also been widely used in the processing of complex curved molds, propellers and turbine blades.

When machining parts, we only need to change the corresponding machining program to realize the machining of new parts, without the need to manufacture or replace many tools and fixtures, and do not need to readjust the machine tool. Therefore, the 4 axis cnc machining center is especially suitable for the processing of single-piece, small batch and trial production of new products.

(2) High machining accuracy

Product quality is stable. The 4 axis cnc machining center adopts rolling guide rails or sticks with frictional resistance, so it can crawl at low speed.

The closed-loop and semi-closed-loop servo systems are equipped with high-precision position detection components, and the position error is fed back to the computer at any time, so that the error can be corrected in time, so that the 4 axis cnc machining center can obtain high machining accuracy.

In addition, the machining process of the 4 axis cnc machining center is completely automatic, which is the error caused by the operator, so that the size of the same batch of parts is consistent and the machining quality is very stable.

(3) High productivity

The time required for parts processing includes manoeuvring time and auxiliary time. 4 axis cnc machining center can effectively reduce these two parts of time.

The speed regulation range of the spindle speed and the tool feed speed of the CNC machine tool is larger than that of the ordinary machine tool, and the machine tool has good rigidity. Fast moving and stopping adopts acceleration and deceleration measures, which can not only improve the speed of idle travel, but also ensure the positioning accuracy, and effectively reduce the maneuvering time.

According to statistics, the productivity of 4 axis cnc machining center is 2-3 times higher than that of ordinary machine tools. When processing some complex parts, the productivity of CNC machine tools can be increased by ten or dozens of times.

(4) Reduce labor intensity and improve working conditions.

Most of the operations of the 4 axis cnc machining center do not need to be done manually, thus improving the working conditions. Scrap and reject rates are also reduced due to fewer operator errors.
