The questions you ask are not clear in a few words, it is best to find a technical book related to wire cutting to learn, and all problems will be solved.
The processing cost varies from place to place, but is generally 1 cent per square millimeter. The thicker the material, the higher the unit price. It's a good idea to inquire about the processing costs in your place.
The machining accuracy is generally fast, the accuracy of the wire is about the same, the cutting hole should be pierced through the wire hole, and if there is a margin for processing, it can also be cut with a knife, and it will not be cut. You just need to touch the wire and find the center position.
The cutting speed of molybdenum wire is related to the thickness of the cutting workpiece, the thicker the workpiece, the slower the molybdenum wire goes. Wire cutting is generally not calculated according to man-hours, but is calculated according to area.

1. If the general processing thickness is less than 100, the pulse width is 30us, and the interpulse is 150us. This parameter is more commonly used, but it depends on your situation.
2. The larger the pulse width, the greater the current, and the faster the processing, but the worse the finish. The larger the intervein, the smaller the current, the slower the processing speed, and the better the finish.
3. The machine tool is composed of a bed, a wire storage mechanism, a wire frame, an XY workbench, an oil tank and other components. The molybdenum wire wound on the wire storage cylinder is subjected to a high-speed grinding and re-grinding motion through the wire frame.
4. The processed workpiece is fixed on the XY worktable. The movement in the X and Y directions is each controlled by a stepper motor. Every time the numerical control system sends out a signal, the stepper motor takes a step, and drives the lead screw in both directions to rotate through the intermediate transmission mechanism, so that the X and Y workbenches are fed respectively.

1. EDM wire cutting
Wire-sinked wire cutting machine (wireelectric discharge machining referred to as WEDM), which belongs to the category of electrical processing, was developed by the former Soviet Union Lazarenko and his wife when they studied the phenomenon and causes of the damage caused by spark discharge corrosion of switch contacts, and found that the instantaneous high temperature of electric sparks can melt and oxidize local metals and be corroded, thus creating and inventing the EDM method.
The wire cutting machine was also invented in the former Soviet Union in 1960, and China was the first country to use it for industrial production.
2. Physical principles
Free positive ion states and electrons accumulate in the field, quickly forming a conductive channel that is ionized. At this stage, an electric current is formed between the two plates. As a result, there are countless collisions between the particles, forming a plasma region, which soon rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some material on the surface of the two conductors, and at the same time, due to the vaporization of the electrode and the dielectric liquid, a bubble is formed, and its pressure rises regularly until it is very high.
Then the current is interrupted and the temperature drops suddenly, causing the bubbles to turn inward**, and the resulting power throws the melted material out of the crater, and then the corroded material re-condenses into small spheres in the dielectric solution and is discharged by the dielectric solution. Then through the monitoring and control of NC control, the servo mechanism is executed to make this discharge phenomenon uniform and consistent.
3. Classification of wire EDM
Distinguish between fast wire cutting, medium wire cutting, and slow wire cutting.
1. The wire walking speed of EDM wire cutting is 6 12mm s, and the electrode wire moves at high speed, and the cutting accuracy is poor.
2. Wire EDM wire cutting is a new process developed in recent years on the basis of fast wire cutting to realize the function of frequency conversion multiple cutting.
3. The wire walking speed of EDM wire cutting is that the electrode wire does low-speed unidirectional movement, and the cutting accuracy is very high.

Summary. Hello, we are glad to answer the question that the parameter setting of wire cutting copper needs to be determined according to the specific workpiece material, thickness, shape and requirements. In general, here are some commonly used parameter settings:
1.Discharge current: generally between 2-4A, which is determined according to the thickness and shape of the workpiece.
2.Discharge pulse width: generally between, depending on the thickness and shape of the workpiece.
3.Working solution: generally use deionized water or add a certain proportion of working solution additives.
4.Working speed: generally between 10-30mm min, which is determined according to the thickness and shape of the workpiece.
5.Linear speed: generally between 8-12m s, which is determined according to the thickness and shape of the workpiece.
6.Wire Diameter: The wire diameter generally used.
The above parameters are for reference only, and the specific parameter settings need to be adjusted according to the actual situation. When setting the parameters, it is necessary to pay attention to maintaining a stable discharge state and avoid over-discharge or under-discharge, so as not to affect the cutting quality.
Hello, we are glad to answer for you that the parameter setting of wire-cut copper needs to be determined according to the specific workpiece material, thickness, shape and trembling pants banquet requirements. Generally speaking, here are some commonly used parameter settings:1
Discharge current: generally between 2-4A, which is determined according to the thickness and shape of the workpiece. 2.
Discharge pulse width: generally between, depending on the thickness and shape of the workpiece. 3.
Working solution: generally use deionized water or add a certain proportion of working solution additives. 4.
Working speed: generally between 10-30mm min, which is determined according to the thickness and shape of the workpiece. 5.
Linear speed: generally between 8-12m s, which is determined according to the thickness and shape of the workpiece. 6.
When setting the parameters, it is necessary to pay attention to maintaining a stable discharge state and avoid over-discharge or under-discharge, so as not to affect the cutting quality.
How much copper current is used at a height of 150, and what is the proportion of the interpulse width between the veins.
Generally speaking, the current used in the destruction of 150 high-base surplus grandchildren is between 6-8A. Generally speaking, the interpulse pulse width is inversely proportional to the size of the electrical pulsation chain, that is, the larger the current, the smaller the interpulse pulse width, and vice versa. It is recommended to adjust it according to the condition of the material in the actual operation to achieve the best cutting effect.
I have carbon deposits and can't cut now, is this too much current?
Yes, in the process of wire cutting, if the current is too large, it will cause too much discharge energy between the electrode and the workpiece, and generate too much heat, so that the surface of the workpiece will be deposed, which will affect the cutting effect. At this time, it is necessary to appropriately reduce the rapid current of electric lifting and adjust the collapse discharge parameters to ensure the cutting quality.

1.Before setting the wire cutting parameters, you need to determine the size, thickness, shape and type of sheath of the cutting wire used. Once these parameters have been determined, it is time to parameterize the cutting line.
Before setting the wire cutting parameters, you need to determine the size, thickness, shape and sheath type of cutting and vertical cutting wire used. Once these parameters are determined, the cutting line can be parameterized.
2.According to the different materials and shapes of the cutting line, the key can be divided into several parts: stubble breaking depth, cutting speed, solder joint depth, ignoring pixels, solder joint size and cutting mode. Quarrelsome.
3.The depth of stubble is used to indicate the depth at which the genus can be cut; The cutting speed indicates the running speed of the cutting line; The depth of the solder joint indicates the depth at which the cutting line needs to be able to cut off the metal completely. Ignoring pixels indicates a set accuracy range; The size of the solder joint indicates the working width of the cutting line; The cutting mode indicates the mode in which the metal is cut, and there are generally four types: straight, semicircular, flat and tanh (hyperbola).
