The invention discloses a seven-axis 
machine tool. The seven-axis 
machine tool comprises a 
machine tool body and a 
workbench installed on the 
machine tool body, the 
workbench can move in the directionof the 
machine tool body, the two sides of the 
machine tool body are each provided with a stand column, a cross beam is installed on the two stand columns, a ram is movably installed on the surface of the cross beam through a sliding rail, a one-axis connecting piece is installed on the ram through a power 
speed reduction component, a two-axis connecting piece is installed on the surface of the 
tail end of the one-axis connecting piece through the power 
speed reduction component, a three-axis connecting piece is installed on the surface of the 
tail end of the two-axis connecting piece throughthe power 
speed reduction component, a four-axis connecting piece is installed on the surface of the 
tail end of the three-axis connecting piece through the power speed reduction component, and a 
machining main shaft is installed on the surface of the tail end of the four-axis connecting piece through the power speed reduction component. According to the seven-axis machine tool, a series of structures are arranged, so that the seven-axis machine tool has the seven-axis five-linkage function, a Z-axis component of a traditional machine tool is omitted, the structure is simplified, and 
machining multiple faces of a large workpiece can be carried out.
