You must master these knowledge to do CNC
At present, the economic CNC lathes in my country generally use ordinary three-phase asynchronous motors to achieve stepless speed change through frequency converters. If there is no mechanical deceleration, the spindle output torque is often insufficient at low speed. If the cutting load is too ...Read more -
What are the basic principles of mechanical drawings?
There are many basic rules in mechanical drawing, and ASME Y14.5-2009 stipulates 16 basic rules, which everyone must know when drawing, reading or reviewing drawings. The following will introduce these 16 basic rules one by one. Article 1: Except for reference dimensions, maximum and minimum dim...Read more -
The origin of CNC tools, it is hard to imagine the greatness of mankind!
The development of cutting tools plays an important role in the history of human progress. As early as the 28th to 20th century BC, brass cones, copper cones, drills, knives and other copper cutting tools appeared in China. In the late Warring States period (3rd century BC), copper cutting tools ...Read more -
Aluminum alloy laser welding technology
With the development of laser technology and aluminum alloy research and development technology, it is particularly important to further carry out basic research on aluminum alloy laser welding application technology, develop new aluminum alloy laser welding processes, and more effectively expand...Read more -
How to effectively prevent porosity in argon arc welding?
Causes of pores (1) The base material is unclean; the groove edge is not cleaned properly; (2) There are large differences in the composition and properties of the welding material and the base material; (3) Problems with welding shielding gas; a) The argon pressure in the gas cylinder is insuffi...Read more -
Tube-to-tube GTAW welding parameters
Tungsten Inert Gas Welding, abbreviated as TIG. Later, the American Welding Society officially named it Gas Tungsten Arc Welding, and the abbreviation was changed to GTAW. Here we talk about the welding parameters of GTAW for pipe-to-pipe butt welding. When the pipe-to-pipe butt fittings are hor...Read more -
If you want to do argon arc welding well, you must remember these process taboos!
Taboos of Tungsten Inert Gas Arc Welding Process 1 Avoid using DC reverse welding in general welding During DC tungsten inert gas arc welding, the heat generated by the anode is much greater than that of the cathode. Therefore, when using DC positive connection (workpiece positive connection) we...Read more -
Analysis of the causes of incomplete welding of branch pipe platform and its countermeasures
1 Introduction With the development of the oil and gas industry, the market has placed higher and higher demands on the exhaust pressure of natural gas compressors. In addition to high quality requirements for the main components of the compressor, higher and higher requirements are placed on th...Read more -
How many people can master the performance of welding heat affected zone?
The welding heat affected zone (HAZ) is different from the weld. The weld can be adjusted by chemical composition, redistribution and appropriate welding process to ensure the performance requirements, while the performance of the heat affected zone cannot be adjusted by chemical composition. It ...Read more -
