What is processing of large mechanical parts? What is processing of large mechanical parts? Large machine tools are used for processing large mechanical parts. One of the machine tools in this workshop is a MAG Cincinnati U5 general copy milling machine, whose X-axis stroke is as long as 100ft (1ft=0.305m), and the Y-axis stroke is 12ft. Positioning datum: The datum used for positioning the workpiece during processing, called the positioning datum.
As the appearance (or line, point) of the positioning reference, only the unprocessed rough surface can be selected in the first process. This positioning surface is called the rough reference. The processed surface can be used as the positioning reference in each subsequent process. , this positioning surface is called a fine reference. The working part of the reamer includes the cutting part and the calibration part. The cutting part is tapered and is responsible for the main cutting work.
The main deflection angle of the cutting part is 5°-15°, the rake angle is generally 0°, and the rear angle is generally 5°-8°. The role of the calibration part is to correct the aperture, smooth the hole wall and guide. In order to make the processing of mold parts, especially complex-shaped punches, concave mold holes and cavities more automatic, and reduce the workload of fitters, it is necessary to use CNC machine tools to process mold parts.
Milling is mainly used for rough machining and semi-finishing of various planes and grooves, and a fixed curved surface can also be processed with a forming milling cutter. Its processing accuracy can generally reach IT9~IT7, and the surface roughness is Ra6.3~1.6μm. The calibration part includes a cylindrical part and an inverted cone part.
The cylindrical part ensures the diameter of the reamer and is easy to measure, and the inverted cone part can reduce the conflict between the reamer and the hole wall and reduce the hole diameter to a large extent. Therefore, the competitive advantage of exporting machine tool products is weakened. The production conditions of the manufacturing plant include the standard, performance and current state of the machine tool equipment and process equipment, the technical level of the workers, the ability of the factory's self-made process equipment, and the power and gas supply capabilities of the factory and other related materials.
The production conditions of the manufacturing plant include the standard, performance and current state of the machine tool equipment and process equipment, the technical level of the workers, the ability of the factory's self-made process equipment, and the power and gas supply capabilities of the factory and other related materials. Judging from the orders of key enterprises in the machinery industry, the cumulative orders in the past year have shown negative growth, and the orders for construction machinery, ships, commercial vehicles, and power generation equipment have declined most significantly. At the same time, exports have also fallen sharply. The development of machine tools is a major shortcoming of my country's industry. Because of the late start, many of my country's machine tool products are at the low-end level, and high-end machine tools rely on imports.
In addition, if the country can regard plastic machinery as the same as machine tools as the basic machinery of the industry (plastic machinery processing polymer materials, machine tools processing metal materials), as an important part of the national equipment industry, advanced plastic machinery is given the same support as CNC machine tools Special support and preferential policies to promote the plastic machinery industry to play a more obvious leverage role and make greater contributions to the development of my country's equipment industry. The development of the plastic machinery industry must combine my country's national conditions and the basic practice of the existing industry to strengthen three relationships, that is, to associate plastic machinery with the high-end manufacturing industry and seek development from high-efficiency industries; People's lives are closely related to specific needs, highlighting the important status of plastic machinery in the manufacturing industry. The new blown film machines produced by the blown film machine machinery manufacturing industry include sheet blown film machines, PE foam film blown film machines, multi-layer composite blown film machines, color strip blown film machines, heat shrinkable film blown film machines, etc., which are satisfactory to the market In the packaging of various products in the world, the high-end blown film quality has won the favor of high-end commodity packaging.
