How to improve the wear of tungsten steel conductive blocks?

One: Requirements for working fluids The current aqueous solution used as the working fluid for CNC high-speed wire walking EDM tungsten steel conductive block wire cutting processing, with a conventional configuration of 1.10 and processing aluminum material of 3.8. To maintain the cleanliness of the working fluid and ensure its effective operation, the sponge after use can avoid flowing into the water tank, maintain the smoothness of the working fluid, and reduce adhesion. Sponge is regularly changed and washed. Secondly, the reasonable combination of pulse electrical parameters When CNC high-speed wire EDM machining of tungsten steel conductive blocks, a wider pulse width is prone to producing larger alumina or surface adhered alumina particles, and a smaller pulse interval can also produce larger particles. However, electrode wires are prone to adhering to these larger machining particles, which has a significant negative impact on machining. By increasing the no-load voltage value of the pulse current, reducing the pulse width, and increasing the pulse gap, the possibility of sticking to the electrode wire can be reduced. Thirdly, operational skills A sponge can be added to the rear slot of the wire rack, and the high-speed reciprocating electrode wire is rubbed by the sponge to reduce electrode wire shaking and ensure the normal operation of the tungsten steel conductive block power supply.

What are the charging and discharging principles of tungsten steel conductive blocks?

Tungsten steel conductive blocks are passive devices that store energy in the form of electric fields. When needed, tungsten steel conductive blocks can release stored energy into the circuit. Tungsten steel conductive blocks are composed of two parallel conductive plates, filled with insulating or dielectric materials between the plates. When a tungsten steel conductive block is connected to a circuit with a direct current (DC) power supply, under specific circumstances, two processes occur: "charging" and "discharging" of the conductive block. Due to the completion of the charging process of the tungsten steel conductive block, there is no current flowing through the conductive block device. Therefore, in a DC circuit, the conductive block can be equivalent to an open circuit or R=∞, and the voltage vc on the conductive block cannot suddenly change. Tungsten steel conductive blocks are found in almost all electronic circuits and can be used as "fast batteries". In the flash of a camera, tungsten steel conductive blocks act as energy storage components, rapidly releasing energy at the moment of flashing.

How to purchase tungsten carbide steel strips

Hard alloy strip is a type of hard alloy shape, named "hard alloy strip" due to its elongated shape. Also known as "hard alloy square bars", "tungsten steel long bars", "tungsten steel bars", etc. Hard alloy strips are mainly suitable for making various types of hard alloy cutting tools, such as hard alloy woodworking tools and hard alloy cutting strips. Due to their high hardness and good wear resistance, they are also commonly used for making high wear resistant parts in precision machinery and instruments. It is precisely because hard alloy strips have high hardness, good bending strength, and resistance to acid, alkali, and rust that they are widely used in national production and have made great contributions to national production and construction. Hard alloy strips come in various grades based on their different properties and uses. The most commonly used are YG series hard alloy strips, such as YG8 tungsten steel strip, YG3X hard alloy strip, YG6X tungsten steel strip, and YL10.2 hard alloy strip; In addition, there are also YT series hard alloy strips, such as YT5 hard alloy strips and YT14 hard alloy strips; There are also YD201 hard alloy square bars, YW1 hard alloy bars, YS2T hard alloy square bars, etc. The physical and mechanical properties of different grades of hard alloy square bars are not entirely consistent. When choosing, it is necessary to carefully choose according to the usage conditions, environment, purpose, and requirements. If you have any questions about hard alloy materials, please feel free to call us at 18018236888. Our professional alloy technicians will provide you with detailed answers. Below is how to choose and purchase hard alloy strips to share with everyone: 1. When purchasing hard alloy bars, it is crucial to understand their alloy grade, which is the physical performance parameters of the hard alloy bars. This is crucial! 2. When purchasing hard alloy square bars, it is necessary to check their overall dimensions. Accurate hard alloy square bars can reduce a lot of deep processing time, thereby improving your production efficiency and reducing or reducing your processing costs. 3. When purchasing hard alloy square bars, attention should be paid to checking the flatness, symmetry, and other geometric tolerances of the plane. High precision hard alloy square bars produce higher quality products and are much simpler to process. 4. When purchasing hard alloy square bars, attention should be paid to checking whether there are any defects such as edge chipping, missing corners, rounded corners, rubber, blistering, deformation, warping, and overburning at the edges. High quality hard alloy square bars will not have the aforementioned adverse phenomena.

Testing methods for high-strength bolts

The commonly used non-destructive testing methods for high-strength bolts are magnetic particle testing, color testing, and ultrasonic testing. This article focuses on magnetic particle testing. Clean the removed high-strength bolts with solvent, paying special attention to the threads and transition parts during cleaning. Place the high-strength bolt in the longitudinal magnetization coil of the magnetic testing machine. Portable instruments can be used for on-site testing. Longitudinal magnetization is carried out using the wire winding method. Select continuous magnetization and wet method, and carefully investigate the external magnetic marks when spraying magnetic suspension. When the coil passes through low voltage and high current, a longitudinal magnetic field occurs. The high-strength bolt undergoes an induced magnetic field under the effect of a longitudinal coil magnetic field, forming a closed magnetic field in the axial direction of the bolt. If there are cracks that form magnetic leakage, it forms magnetic field leakage. After using magnetic powder, the magnetic mark attracts the magnetic powder to form an enlarged magnetic mark. Magnetic particle testing has a very active induction of cracks on the surface, and the appearance of cracks is intuitive and easy to operate. However, the cleaning workload is too large, which affects the progress of the test. Moreover, the surface has rust and black marks that are difficult to clean. The color contrast between these marks and the magnetic particle is not clear, which affects the investigation of magnetic traces and may lead to leakage. The leakage of magnetic particles adsorbed on the tooth tip of high-strength bolts can also lead to misjudgment.
