What is the material of the conductive block of wire cutting 5

Wire cutting conductive blocks are made of cemented carbide.

i.e. tungsten steel. materials made.

Tungsten steel (cemented carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500, it remains basically unchanged, and it still has a high hardness at 1000.

It is used for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used to cut heat-resistant steel, stainless steel, and high manganese steel.

Difficult-to-machine materials such as tool steel. The cutting speed of the new cemented carbide is equal to that of carbon steel.

Tungsten steel It is recommended that you replace the conductive block with an introductory type, so that you don't pull the wire very !

Wire cutting conductive blocks are mostly made of cemented carbide.

Theoretically, the closer the conductive block of the molybdenum wire is to the workpiece, the better. Many years ago, in order to pursue high efficiency, some manufacturers added a conductive block to the upper and lower parts of the workpiece, and conducted the high frequency from these two conductive blocks to the molybdenum wire, which doubled the efficiency of wire cutting, which also had a certain effect.

In addition, there is a broken wire protection conductive block, which is generally placed in the middle of the wire rack or the virtual ant is the middle of the wire off the frame, which is mainly to press the molybdenum wire at the moment of broken wire, so that the machine tool can be stopped.

Of course, some manufacturers' machine tools will also add a conductive block, especially the wire walking machine tool, which will add a conductive block at the back end. This conductive block plays a role in allowing the molybdenum wire to eliminate the vibration caused by the rotary movement, so that the molybdenum wire can maintain a stable movement when rotating, reduce the shaking of the molybdenum wire, and thus get a better finish. The conductive block not only plays the role of conducting high-frequency electricity, but also keeps the molybdenum wire stable and reduces the jitter of the molybdenum wire.

The function of the wire cutting conductive block: **In the process of cutting and processing, when the current passes through the molybdenum wire and the processing workpiece, the upper and lower two conductive blocks supply power for it, and the upper and lower sections of the molybdenum wire are connected in parallel for power supply, so each section also bears half of the current, and the voltage loss on the molybdenum wire is also reduced by half, so that it can withstand higher current to process.

Summary. Hello, glad to answer for you. It is not fast to cut the contact surface of the wire cutting conductive block, which is directly related to the strength of the wire cutting and the hardness of the material, and has no direct relationship with his tracking distance.

Hello, I am very happy to answer for you. It is directly related to the strength of the wire cutting and the hardness of the material, and it is directly related to the tracking distance.

Hello, I'm glad Qingqinglu answered for you. Wire cutting conductive blocks, generally used are cemented carbide, the higher the wear resistance, the better, the smoother the surface, the longer the life. It is normal for some manufacturers to wire cut conductive blocks to be pulled out of deep grooves by molybdenum wire

Because the molybdenum wire is moving at high speed when working, it will inevitably produce flutter, resulting in poor contact between the molybdenum wire and the conductive block, resulting in the discharge phenomenon and the cutting phenomenon of the conductive block. In addition, the wear of the molybdenum wire on the conductive block is also one of the reasons for the deep drawing groove. Because of this, the conductive block is a wearing part, consumables, often replace the contact surface of the conductive block and molybdenum wire, and in the case of serious wear, it must be replaced with a new conductive block.

First of all, the reasons for this are: aluminum parts are more damaged conductive blocks.

That's because alumina is produced during the cutting process. Alumina is non-conductive and very hard (the sand wheel is alumina's) Spark discharge and mechanical wear occur when the alumina particles are carried to a conductive block by molybdenum wire.

Pay attention to water filtration and cleaning; Reducing the speed of frequency conversion and tracking, reducing the probability of short circuit, can effectively reduce the ignition of conductive blocks. Decrease the pulse width to reduce the size and number of alumina particles; The above is a brief introduction to the reasons why wire cutting aluminum parts will cut conductive blocks.
