Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology, specifically relating to a dual-spindle power turret turning and milling composite machine tool. Background Technology

[0002] A milling-turning machine tool is an advanced machining equipment that integrates the functions of a lathe and a milling machine, and can simultaneously complete multiple machining tasks such as turning and milling.

[0003] Traditional machine tools are typically designed with only a single spindle, a design that presents significant limitations when machining complex parts. Due to the limited number of spindles, multiple machining operations require repeated workpiece clamping, each necessitating readjustment of the positioning datum, leading to frequent interruptions in the machining process. Furthermore, tool changing on traditional machine tools is primarily manual, requiring operators to manually remove and install tools according to machining requirements. This is not only time-consuming and labor-intensive but also prone to human error. This inefficient operating mode directly hinders production efficiency, and the accumulated positioning deviations from repeated clamping significantly affect the machining accuracy of parts, ultimately leading to decreased product quality stability. Utility Model Content
