CNC machine tools, routine maintenance is also very important
The daily maintenance of CNC machine tools requires maintenance personnel to not only have knowledge of mechanics, processing technology and hydraulics, but also knowledge of electronic computers, automatic control, drive and measurement technology, so that they can fully understand and master CN...Read more -
Although the burrs are small, they are difficult to remove! Introducing several advanced deburring processes
Burrs are everywhere in the metal processing process. No matter how advanced precision equipment you use, it will be born together with the product. It is mainly a kind of excess iron filings generated at the processing edge of the material to be processed due to the plastic deformation of the ma...Read more -
Advantages and disadvantages of inclined bed and flat bed machine tools
Machine tool layout comparison The plane of the two guide rails of the flat bed CNC lathe is parallel to the ground plane. The plane of the two guide rails of the inclined bed CNC lathe intersects with the ground plane to form an inclined plane, with angles of 30°, 45°, 60°, and 75°. Viewed from ...Read more -
Difficulties and operating methods of mirror welding
1. Original record of mirror welding Mirror welding is a welding operation technology based on the principle of mirror imaging and uses mirror-assisted observation to control the welding operation process. It is mainly used for welding of welds that cannot be directly observed due to the narrow w...Read more -
28 questions and answers on welding knowledge for advanced welders（2）
15. What is the main function of gas welding powder? The main function of welding powder is to form slag, which reacts with metal oxides or non-metallic impurities in the molten pool to generate molten slag. At the same time, the generated molten slag covers the surface of the molten pool and iso...Read more -
28 questions and answers on welding knowledge for advanced welders（1）
1. What are the characteristics of the primary crystal structure of the weld? Answer: The crystallization of the welding pool also follows the basic rules of general liquid metal crystallization: the formation of crystal nuclei and the growth of crystal nuclei. When the liquid metal in the weldin...Read more -
The most basic knowledge that CNC people must master cannot be bought with money!
For the current economic CNC lathes in our country, ordinary three-phase asynchronous motors are generally used to achieve stepless speed change through frequency converters. If there is no mechanical deceleration, the spindle output torque is often insufficient at low speeds. If the cutting load...Read more -
Practical thread calculation formula, hurry up and save it
Relevant calculation formulas used in fastener production: 1. Calculation and tolerance of external thread pitch diameter of 60° profile (National Standard GB 197/196) a. Calculation of basic dimensions of pitch diameter The basic size of thread pitch diameter = thread major diameter – pitc...Read more -
CNC machining center programming instructions, if you don’t know it, come and learn it
1. pause command G04X (U)_/P_ refers to the tool pause time (feed stops, the spindle does not stop), and the value after address P or X is the pause time. The value after For example, G04X2.0; or G04X2000; pause for 2 seconds G04P2000; However, in some hole system processing instructions (such as...Read more -
The top ten problems that are most easily overlooked in welding. Details determine success or failure. Please read it patiently.
There are many things that need to be paid attention to during the welding process. If ignored, it may lead to big mistakes. Details determine success or failure, please read it patiently! 1 Don’t pay attention to choosing the best voltage during welding construction [Phenomena] During welding, ...Read more -
How to weld heat-resistant steel The welding process is here to tell you
Heat-resistant steel refers to steel that has both thermal stability and thermal strength under high temperature conditions. Thermal stability refers to the ability of steel to maintain chemical stability (corrosion resistance, non-oxidation) under high temperature conditions. Thermal strength r...Read more -
Causes and preventive measures of welding pores in J507 electrode
Porosity is the cavity formed when the bubbles in the molten pool fail to escape during solidification during welding. When welding with J507 alkaline electrode, there are mostly nitrogen pores, hydrogen pores and CO pores. The flat welding position has more pores than other positions; there are...Read more
