What is Tungsten Fishing Bead? [Cemented Carbide Inserts]

What is Tungsten Fishing Bead?
Fishing beads can be as an attractor or be a component of the rig when you are fishing. Fishing beads can be made from plastic, brass, lead, tungsten and so on. And they come in many different colors.There are also luminous beads made of plastic which glow in low light when the water you are fishing has low visibility to attract fish. However, tungsten alloy fishing bead becomes more and more popular because of its good properties. Tungsten fishing bead is made from tungsten alloy, so some peple call tungsten alloy fishing bead as tungsten fishing bead.

Why Choose Tungsten Fishing Beads?
Tungsten fishing beads are twice as heavy as brass and heavier than lead. Perfect for any fly that has to get down deep. And tungsten fishing bead also enable the fisherman to fish in fast flowing water where the fish lie deep. Furthermore ,tungsten alloy fishing bead is non-toxic, therefore tungsten fishing lead is friendly to the environment. So tungsten alloy fishing bead is the best friend to fisher man.

Why better to use three-flute endmill for roughing aluminum?

Two-flute milling cutters and 3-flute?milling cutters are usually used to process aluminum alloys materials. Simply distinguished from the surface by the number of blades,?2-flute carbide end mill are suitable for rough Machining, 3-flute end mill?is selected for finishing.

Let’s first understand the characteristics of aluminum alloy materials:

1. The hardness of aluminum alloy is low. Compared with titanium alloy and other quenched steels, the hardness of aluminum alloy is lower. Of course, it has been heat-treated or die-cast aluminum alloy has a high hardness. The HRC hardness of ordinary aluminum plates are generally below HRC40 degrees. Therefore, when machining aluminum alloy, the load of the tool is small. Because aluminum alloy has better thermal conductivity, the cutting temperature of milling aluminum alloy is relatively low, which can increase its milling speed.

2. Low plasticity of aluminum alloys have low plasticity and low melting point. When processing aluminum alloy, the sticking problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the main reason for processing aluminum alloy is that the effect of sticking knife and roughness is not good. As long as the two major problems of sticking knife and processing surface quality are solved, the problem of aluminum alloy processing will be solved.

3. The tool is easy to wear because the unsuitable tool material is used. When machining aluminum alloy, the tool wear is often accelerated due to problems such as tool sticking and chip removal.

Generally, 3-blade aluminum milling cutters are used to process aluminum alloys. Secondly, due to the difference in processing conditions, 2-flute?ball-end Water Well Drilling Rig cutters?or 4-blade flat?endmill bits?are likely to be used. However, it is recommended that in most cases, a 3-flute flat-bottomed end mill can be used.

1. The choice of tungsten steel milling cutter for aluminum is generally 3 flutes, and the material is generally YG cemented carbide, which can reduce the chemical affinity of the tool and aluminum alloy. General CNC tool brands have a series of special milling cutters for processing aluminum alloy.

2. Milling cutters for high-speed steel and aluminum are relatively sharp, and they can also process aluminum alloys well.

3. Cutting parameters of milling aluminum alloy.

Generally, high-speed and large-feed milling can be selected for processing ordinary aluminum alloy.

Secondly, choose a larger rake angle as much as possible to increase the chip space and reduce the phenomenon of sticking. If it is a finishing aluminum alloy, you cannot use water-based cutting fluid to avoid the formation of small pinholes on the processed surface. Generally, kerosene or diesel oil can be used as the cutting fluid for processing aluminum plates.

The cutting speed of machining aluminum alloy milling cutters differs due to the material and parameters of the milling cutter, and the processing technology. The specific cutting parameters can be processed based on the cutting parameters given by the manufacturer.
