Performance introduction of tungsten steel nozzle

Tungsten steel nozzle is a nozzle produced from tungsten steel material. Because tungsten steel has high hardness and high wear resistance, tungsten steel nozzles produced from tungsten steel have a longer life than nozzles of other materials.

Tungsten steel material refers to the alloy material obtained by mixing, pressing and sintering forming of WC and Co powder as main raw materials, using powder metallurgy method through a series of processing techniques. It has the
characteristics of hardness, high strength, corrosion resistance and stainless.

Tungsten steel with high hardness and wear resistance shall be made according to ISO standard. This classification is based on the material category of the workpiece (P, m, K, N, s, H). Different tungsten steel materials have different uses, such as turning, milling, hole processing, thread processing, slot cutting, etc. Tungsten steel has high hardness and wear resistance, which is often used to make metal cutting tools, measuring tools, molds, etc. Generally, when the material hardness is high, the wear resistance is also high; when the bending strength is high, the impact toughness is also high. However, the higher the hardness of the material, the lower the bending strength and impact toughness.

The composition ratio of the tungsten steel nozzle is about 18% tungsten. The hardness of the high-hardness and high-wear-resistant tungsten steel is Vickers 10K, second only to diamond. Because of this, the tungsten steel nozzle has the
characteristics of not being easily worn. High hardness and wear-resistant tungsten steel is used to produce suction nozzles, lathe tools, impact drill bits, glass cutter bits, and ceramic tile cutters. The tungsten steel nozzle has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at 500 ℃, it basically remains Change, it still has a high hardness at 1000 ℃.

The nozzle used in LED packaging can overcome the short life of materials such as bakelite nozzles and rubber nozzles, and due to its plasticity, it can be made into a tungsten steel nozzle with a smaller inner hole. Take the Yamaha YG100 nozzle core 211A,212A,213A,214A,215A,216A,219A as an example. When this tungsten steel nozzle is used to produce small-sized LEDs, it overcomes the fact that the wafer is too small, resulting in the appearance of broken edges and dark jumps on the edges of the crystal grains, which significantly reduces the IR defect rate of the LED.

How does the nozzle of Samsung placement machine correspond to the material selection

Image
Regarding how to choose the material of the Samsung SMT nozzle , the most encountered problem is that many technicians and customers do not know the component selection corresponding to the Samsung nozzle. Today I will briefly introduce how the material of the Samsung SMT nozzle corresponds to the material Selection. Take the nozzle of Samsung Chip Mounter CP-45NEO / CP-45FV as an example: Samsung CP-45NEO Nozzle Assembly: CN020,CN030,CN040,CN065,CN110,CN140,CN220,CN400, CN400N ,CN750, CN1100 Samsung CP-45FV Nozzle Assembly: TN020, TN030 , TN040 , TN065 , TN140 , TN220 , TN400 , TN750 , TN1100 Suction hole diameter: 0.18mm, 0.28mm, 0.38mm, 0.65mm, 1.4mm, 2.2mm, 4.0mm, 7.5mm, 11mm. Selection principle of suction nozzle: 1. The diameter of the selected nozzle hole cannot be larger than the minimum size of the component. 2. The diameter of the selected nozzle hole should not be too small than the minimum size of the component, and the general proportion is 1:1.2-1.7, which is ...

Solution to the dropping of nozzle of JUKI mounter ke-2050

Image
Juki KE-2050 nozzle is not directly connected to the placement machine, there is actually another part connected between them-nozzle holder. We installed the nozzle of the Juki placement machine KE-2050 on the nozzle holder, and then installed the nozzle holder on the placement machine. This will cause a problem that the nozzle is easily separated from the nozzle holder while playing. The reasons for the above problems may be as follows, we analyze them one by one: 1. The Juki KE-2050 nozzle holder with the nozzle is worn out during use and the size becomes smaller, which does not match the nozzle holder. At this time, replace the new nozzle holder. Of course, this is only a temporary solution to the problem, and the situation needs further analysis. 2. It is not the problem of the entire nozzle holder, but the inner gasket is worn or dropped in production, and it is sufficient to replace or reinstall a gasket. 3. The cause of the brake pads, there should be a phenomenon of jitter in...

Why is the black material commonly used for the nozzle of the placement machine?

Image
The SMT placement equipment has now become the mark of our fully automatic production line, and the SMT placement equipment can accurately and quickly place components all rely on the role of the nozzle. When we use the nozzle of the placement machine, we will definitely find that the nozzles are all black. Why should we use black nozzles? To understand this problem, we must first know what role the nozzle has? The nozzle of the placement machine is not only the key part of the placement machine to pick and place the sucked component, but also the background when the camera of the optical vision system takes a picture. It mainly uses the suction effect of the vacuum to suck the component, and Use blowing to put the components adsorbed on the nozzle to the coordinate position of the circuit board. Almost every nozzle will have a reflective background, which is mainly to have a good background when the image is taken, so that the target information can be accurately highlighted during ...
