Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a five-axis machining machine tool. Background Art

[0002] In the fields of titanium alloy, high temperature alloy and high strength steel, the traditional processing method is used. When the tool contacts the workpiece for cutting, there is a force between the tool and the workpiece, which causes a slight elastic deformation of the cutting tool and the workpiece, affecting the processing accuracy. At the same time, it is difficult to process holes in some special positions, such as the processing of small holes in the engine combustion chamber, using conventional processing methods. Therefore, the existing technology uses laser processing holes.

[0003] CNC machine tools are digitally controlled machine tools. They are automated machine tools equipped with a program control system. Information is input into the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0004] Cam machine tools need to process multiple sides of workpieces during processing, and existing cam machine tools cannot achieve the various large swing angle adjustments required for processing. If the workpiece is transferred and clamped multiple times to achieve overall processing, the processing accuracy of the workpiece will be affected due to multiple clamping processes.

[0005] During the process of machining the workpiece, slag may be generated and splashed. The slag splashed into the moving parts or the processing parts is difficult to clean and will affect the operation of the moving parts and other parts. Utility Model Content
