Detailed explanation of the characteristics and Operation steps of the Q-2 metallurgical cutting machine The metallurgical cutting machine is mainly used for the metallurgical structure of cutting materials,The metallurgical structure refers to the chemical composition in the metal,And the physical properties are the same as the crystal structure,It mainly includes solid solution and pure substance and metal compound.The influence of metallurgical structure on external factors,It will cause changes in the content structure of the metal or alloy,The metallurgical cutting machine is a precision instrument for performing this operation,It is usually used in a special laboratory,Xiaobian introduces the characteristics and Operation steps of the metallurgical cutting machine.Q-The cutting grinding wheel of the cutting machine is directly fixed on the shaft of the motor,Using the swing of the saw frame to cut the sample motor fixed in the fitter and fix it on the base,The bushing is set on the shaft of the motor,Th

Sewing machine sometimes jumpers sometimes don't jumper what's going on Put the machine needle down to the lowest level,Check the distance between the machine needle and the swing hook as shown in the figure,The hook should be in the groove above the needle eye,If not,Adjust the needle stick to complete.In addition, the shuttle part is removed to clean up the impurities,This is also the main problem.Sewing machine,The jumper is the most common and complicated one.It is affected by many factors,For example,Needle fine,The line is tight,Material thickness,The pressure is too small.But as far as the problem itself is concerned,There is only one reason for the jumper,That is, the shuttle is not on the line at the needle.Therefore, we only need to find a way to let the tip of the shuttle hook the line that the needle spit out.When the conventional adjustment does not work,Try another method: First of all,Put the needle down a little more than usual.The specific position is: loose off the three screws of the shutt
