After the transformation, the function and economic benefit evaluation can be realized. The horizontal key milling machine can realize the numerical control function of the three-axis linkage, and can fully utilize the advantages of the precise positioning of the four reference surfaces of the rotary table, and the workpiece can be loaded on the turntable reference surface at one time. The use of numerical control functions to complete the processing of the three-dimensional multi-process and improve the processing precision of the product.
CNC programming, CNC machining graphics simulation software, CAD/CAM/CNC integrated control software can be further developed. All experimental software has off-line simulation and online control functions, which can use CRT to simulate output, and output control results through small experimental milling machine to get out of the expected trajectory. Using the powerful display function and multimedia technology of PC platform, it laid the foundation for CAI of machine tool numerical control principle and system course.
In order to prevent the tool from extending too long, the sliding table is used to drive the rotary table (6 axes) to move in the direction of the boring axis to complete the deep hole machining, and the semicircle is processed by the circular interpolation method to ensure the flatness of the bottom of the hole and The coaxiality of the holes. The use of programmed machining of parts also greatly increases production efficiency.
The horizontal boring and milling machine weighs 64t, and the maximum weight of the turret is 24t. It takes about 3.5 million yuan to purchase a CNC horizontal turret milling machine of corresponding scale in China, and the actual cost after the transformation of CNC electrical equipment is only 38. Ten thousand yuan (including replacement of a new spindle). The successful transformation of the horizontal boring and milling machine will alleviate the tension of CNC punching machine processing in turbine manufacturing, which will bring greater economic benefits.
