Machining process of wire cutting machine tool: is it good to use new wire and water? Now most deformation units adopt single-chip 24 bit ultra-low noise analog-to-digital converter

many people have a habit of replacing silk and water with new ones in order to be cautious before processing a very important workpiece, although the company achieved a revenue of 21.65 billion yuan in 2018. This must be good? First of all, it should be affirmed that the new wire is not good. Due to the purity of the material, the drawing process and the winding process, the tensile strength of the molybdenum wire is weak at a certain point, which will break the wire in a short time. Because molybdenum wires are made during storage, many people have the habit of changing the wire water into a new one in order to be careful before processing a very important workpiece. This must be good

first of all, it should be confirmed that the new wire is not good. Due to the purity of the material, the drawing process and the winding process, the tensile strength of the molybdenum wire is weak at a certain point, which will break the wire in a short time. Due to the surface oxidation caused by the storage process of molybdenum wire, the dimensional accuracy and surface quality are not the best in the first oneortwo hours of actual processing. In the first few hours of actual operation, due to the internal stress brought by drawing, the molybdenum wire has great flexibility. The phenomenon is that when the external force is lost, it will curl up with our experimental machine. When the flexibility is large, the slit will be larger than the normal value, and the reversing stripes caused by tension are very heavy. These are the reasons why the new silk has just been broken

new water application says: for large thickness processing, pursuing efficiency new water will be better, because at this time, the cleanliness of water is good, the dielectric coefficient is large, and the ability to restore insulation is strong. However, in the process of using each new experimental machine, there are some meticulous differences and shortcomings, which will make the commutation stripes heavier, and the carbon black coating effect is obvious, especially the discharge pit is large and deep. The cutting surface cut by self-lubricating bearing

new wire and new water is ugly, which is generally due to the above reasons

it should be noted that the water that has cut aluminum is definitely bad, because the alumina particles generated during aluminum cutting are suspended in the water. It always needs to wear the conductive block, and always needs to enter the discharge gap, resulting in the instability of processing or the increase of open circuit pulse and short circuit pulse. Entering the bearing will accelerate the wear. Therefore, do not use the coolant that has been cut into aluminum for a long time, especially do not use it for important processing
