Slow moving wire oil cutting is a broad and important in the machinery, auto parts and standard parts industry. In the processing process of iron core die and rotor riveting die, the error of slow moving wire oil cutting is very small, which keeps the special precision of the die and improves the life. There should be no error in the process of slow wire oil cutting. If you do not notice it, the workpiece will be scrapped, and the cost will be increased, and the processing time will be prolonged. The next step is to understand the slow wire oil cutting process!

There are two kinds of corrosion of metal in slow wire oil cutting: melting and gasification. Wide pulse width action time is long, easy to cause melting processing, the workpiece surface morphology is bad, metamorphic layer thickening, internal stress increase, easy to crack. When the pulse width is small to a certain value, the action time is very short, forming gasification processing, can reduce the thickness of the metamorphic layer, improve the surface quality, reduce the internal stress, avoid crack generation.

Slow-moving wire is a kind of machining machine tool which uses continuous moving fine metal wire (called electrode wire) as electrode to carry out pulse spark discharge on the workpiece to remove metal and cut into shape. The phenomenon of light voltage discharge in loose contact between the on-line electrode and the workpiece during slow wire processing. When the flexible electrode wire and the workpiece close to the commonly considered discharge gap (such as 8 ~ 10μm), no spark discharge occurs, even when the electrode wire has been in contact with the workpiece, can not see the gap from the microscope, also often can not see the spark, only when the workpiece electrode wire top bending and offset a certain distance (a few microns to tens of microns) when the normal spark discharge occurs. At this time, when the wire electrode is fed 1μm, the discharge gap does not decrease by 1μm, but the electrode wire increases the tension between the wires, and the workpiece increases the lateral pressure. Obviously, only when the electrode wire and the workpiece maintain a certain slight contact pressure can spark discharge be formed. It is concluded that there is some kind of insulating film medium between the electrode wire and the workpiece.

Slow wire processing is widely used in industry. Slow-moving wire is a kind of CNC machining machine tool that uses continuous moving fine metal wire (called electrode wire, generally copper wire and molybdenum wire) as electrode to carry out pulse spark discharge on the workpiece, generate high temperature above 6000 degrees, corrode the metal and cut into the workpiece. The principle of slow wire processing is that there is a gap between the online electrode and the workpiece, and the continuous discharge removes the metal phenomenon.

Oil cutting processing is the slow wire cutting oil as the medium of the oil cutting machine processing, is absolutely high precision equipment, usually high requirements of the workpiece need to choose the oil cutting machine to process, slow wire cutting processing accuracy up to ±1μm, commonly used Shadik oil cutting machine, Archie oil cutting machine and so on.

Oil cutting processing is mainly used for high-precision processing, so how big is the line diameter of oil cutting processing?

Oil cutting processing line diameter of φ0.02 ~ φ0.03 ~ φ0.05 ~ φ0.07 ~ φ0.1 ~ φ0.15 line diameter, according to the processing needs, choose different line diameter, such as Dongguan Taijin Japan Shadik oil cutting machine commonly used φ0.03 ~ φ0.07 line diameter, Swiss Archi oil cutting machine can reach φ0.02 line diameter processing, Can meet the daily high precision mold parts processing, coupled with precision imported testing instruments, to ensure its excellent factory accuracy.
