Често коришћена машина за испитивање затезања, немојте чекати да се делови оштете пре одржавања
Tensile testing machine is also known as universal material testing machine. As an important part of the instrument, different materials need different fixtures, which is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results. But the regular use of tensile testing machine is also caused by the impact, some parts may fail, so when these parts fail, how should it be maintained 1 When the tension machine is loaded, тхе... 22мар
The use of vibration testing machine precautions and maintenance finishing steps
Vibration testing machine is widely used in national defense, aviation, aerospace, комуникације, електроника, automobiles, home appliances, medicine and food packaging and other industries laboratory and production line vibration test of product samples. This type of equipment is used to detect early faults, simulate the sinusoidal and random vibration capacity suffered by the product during manufacturing, assembly, transportation and use, and assess the vibration resistance, reliability and integrity of its structure. Several details that should be paid attention to when using... 21мар
There are several factors that can analyze the quality of photoelectric direct reading spectrometer
Photoelectric direct reading spectrometer is a rapid quantitative analysis instrument for the analysis of ferrous metals and non-ferrous metals. This instrument is widely used in metallurgy, machinery and other industrial sectors, to carry out online analysis before the smelting furnace and product inspection in the central laboratory, is one of the effective means to control product quality.

После металографског брушења, постоји неколико метода полирања
После млевења, the metallographic specimen needs to be polished to remove the abrasion marks and deformation layers generated by the grinding process on the specimen, so that it becomes a smooth mirror. Сада, the methods of polishing samples include mechanical polishing, electrolytic polishing, chemical polishing and composite polishing. 1.Mechanical polishing: polishing in a special polishing machine. Mechanical polishing is mainly divided into two steps: rough polishing and fine polishing. Rough polishing: The purpose is to remove the polished deformed layer. У... 20мар
Роцквелл тестер тврдоће у коришћењу процеса наилази на квар има како да реши
Rockwell hardness tester is suitable for metal Rockwell hardness test. This test method is characterized by measuring the indentation depth and reading the hardness value of the sample directly on the dial or digital display screen of the hardness tester, which is convenient, једноставан, rapid and high efficiency. Small indentation, small damage on the working surface of the parts, suitable for batch parts testing; Rockwell hardness test has a wide range. Because the hardness tester is affected by external and... 20мар
