Advantages of 3D printing technology(1) Save materials. It does not need to eliminate the leftover materials, improves the utilization rate of materials, and reduces the cost by abandoning the production line;(2) It can achieve high precision and high complexity, and can manufacture very complex parts which can not be manufactured by traditional methods;(3) Without traditional tools, fixtures, machine tools or any molds, 3D CAD graphics of any shape can be directly generated into real products;(

CNC machining is also called Computer Numerical Control machining. Before programming, it is necessary to analyze the process of the processed parts, draw up the processing plan, select the appropriate tool and determine the cutting parameters. In programming, some technological problems such as tool setting and machining route need to be dealt with. Therefore, the process analysis in programming is very important. When processing parts on ordinary machine tools, the operation procedure of each

Feature 1: symmetrical structure, frame in frame structure and gravity center double drive mode are adopted to effectively improve the rigidity of the machine tool and suppress vibration.Feature 2: improve the machining accuracy, improve the service life of machine tool and cutter, and enhance the reliability of machine tool.Feature 3: it has the function of on-line programmable control of pushing and pulling force of workpiece, which can fully improve the internal prestress of workpiece, improv

3 axis machining center and vertical machining center are widely used in traditional mold processing to complete the workpiece milling. With the development of mold manufacturing and processing technology, the ball end milling cutter commonly used in traditional mold processing has obvious advantages, but if vertical machining center is applied, its bottom linear speed is zero and its finish is poor, In this way, the weakness of traditional mold processing is gradually revealed. 5 axis machining

①A large number of tooling is reduced, and complex tooling is not needed for parts with complex shapes. To change the shape and size of parts, only the part processing procedure needs to be modified, which is suitable for the development and modification of new products.②The machining quality is stable, the processing precision is high, the repetition precision is high, which is suitable for the machining requirements of the aircraft.③The production efficiency is high under the condition of m
