国际上对复合化机床尚无明确定义，正处于创新发展之中。复合加工又叫完全加工、多功能加工。早期曾将加工中心称为复合加工机床。但是随着复合加工技术的不断发展与进步

Boring, refers to the forged, cast or drilled holes for further processing. Boring can expand the hole diameter, improve accuracy, reduce surface roughness, but also can better correct the original hole axis of the skew. Boring can be divided into rough boring, semi-fine boring and fine boring.

随着工业发展速度越来越快，机床加工在工业生产中愈加重要。作为机床加工重要工具的机床也逐渐演化出诸如车床、铣床、刨床、镗床、钻床、磨床等常见的机床类型。说到各种工艺的机床加工工艺

The innovative application of five-axis machining technology in mould manufacturing With the continuous development of the manufacturing industry, especially in the field of mould manufacturing, five-axis machining technology has gradually become an important processing means. Five-axis machining refers to the processing of two rotary axes on the basis of three linear axes.

The fundamental difference between 5-axis precision machining technology and traditional machining technology is that it achieves multi-axis linkage by adding two rotary axes, which can complete the machining of complex parts in a single clamping, thus avoiding the errors brought about by traditional technology due to multiple clamping from the source.

Turn-mill composite machining centre is a place where lathe and milling machine are processed together. In order to improve the machining efficiency and machining accuracy of complex shaped products, craftsmen have been seeking for more precise machining process methods.
