Slow-moving wire machining is a kind of CNC machining machine tool that uses continuous moving fine metal wire (called electrode wire, generally copper wire) as electrode, conducts pulse spark discharge on the workpiece, produces high temperature above 6000 degrees, corrodes the metal and cuts 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. The following Xiaobian to introduce to you about the working principle of slow wire processing machine tools and processing waterways are what? The contents of Welcome to read!
Working principle of slow wire processing machine:
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 exists some kind of electrochemically generated insulating thin film medium between the electrode wire and the workpiece.
What are the waterways for slow wire processing?
The slow-moving wire has a set of water circulation system, which is used to purify the water and deionize the working liquid to achieve the role of reprocessing.
1. The storage place of the working liquid of the water tank includes the sewage tank and the pure water tank.
2. The sewage pump pumps the sewage out into the filter, the ion pump the filtered water into the resin bucket to deion, the water pump quickly injected the working liquid into the working tank to achieve the purpose of immersion processing, high pressure pump with high power to the pure water into the upper and lower head with high pressure jet to remove the work produced in the electromelt and wire wheel wire, a variety of machine tools of water layout is different, but the principle is the same.
3. Three-way valve Its purpose is to separate the water flow to achieve different functions, by air conversion.
4. Position sensor (close switch) three-way valve position induction, through the input electrical signal through the motherboard after the position information displayed on the screen.
5. Water level sensor sewage tank pure water tank each 1, induction water level to determine whether each pump can work, below the water level of the input electrical signal after processing by the motherboard output electrical signal to stop the operation of related pumps.
6. The purified water from the cotton core is used to wash the conductive block.
7. Filter the metal debris in the sewage.
8. Water pressure sensor filter, the water pressure sensor on the cotton core is used to determine whether the water pump can be injected into it, with overpressure protection.
9. The resistivity measurement of ion sensor can measure the value of ions flowing into the resin barrel.
10. Resin cask A container for storing resin, an extract from petroleum used to deionize.
