Tungsten carbide groove cutter has high cutting accuracy and longer service life, which often used in manufacturing run-out groove in bearing parts, over-run of grinding wheel, snap ring groove and sealing groove and bore groove.

Types

There are many types of cutting groove, such as run-out groove in bearing parts, over-run of grinding wheel, snap ring groove and sealing groove and bore groove and so on. Lathe grooving cut divided into the outer tank, inner hole and the end face grooving. The tool can be used to cut the outer groove of turning face groove. Cut the outer groove and the end slot are rectangular arbor, and cut the groove commonly round or square arbor. In addition, the combined size of the blade and arbor must be less than the hole diameter to ensure the accuracy and improve the efficiency.

Characteristic
1. Small feed rate, even cutting thickness, large unit cutting force, better heat dissipation performance;
2. High cutting speed and uniform distribution;
3. The workpiece rotating and the tool cut continuously and form Archimedes screw surface;
4. Narrow edge width, suspended elongation, so it easily to vibrate when cutting or grooving.

Tungsten carbide casting die has better performance in heat resistance and fatigue resistance, which make casting component obtain good structure and mechanical properties by the extrusion of the molds. There are many types of tungsten carbide casting die mainly based on the manufacturing equipment, such as tire mold, hammer forging die, mechanical forging die, upset forging die and roll forging die, etc.

Tire mold: Used in free forging, is suitable for small forging parts and small batch production;
Hammer forging die: Under dynamic action of forging equipment, the blank forced plastic flow forming die in the die bore, resulting in higher quality than free forging;
Mechanical forging die: Mechanical presses for the forging blank or semi-finished molding;
Upset forging die: In the horizontal forging machine forging the blank is formed into a mold or semi-finished products.

Compared with casting process, metal after forging can improve its organizational structure and mechanical properties. Since the deformation of the metal and recrystallization, the original coarse dendrite and columnar grains become finer grain, recrystallized structure of uniform size. In addition, to ensure the continuity of the metal forging fibrous tissue, fibrous tissue and make forging shape consistent metal flow lines intact, to ensure parts with good mechanical properties and long service life with precision forging; cold extrusion, warm extrusion process to produce forgings, castings are unmatched by forging metal was pressured by the shape or suitable plastic deformation of the compression force required to shape objects.

4. Clearance angle grinding center and side blade knife with a spiral groove cutter against the top, align wheel, push the sleeve cutter grinding corrugated side edge.

Tungsten copper FGM (Functionally Graded Material) has many processes, mainly include PM (Powder Metallurgy), plasma spraying, vapor deposition and SHS (Self-propagation High-temperature Synthesis). PM has the advantages of simple equipment, low cost, easy to realize large-scale production, etc., but it needs strict control of holding temperature, holding time and cooling rate and it is only suitable for the products with simple structure and dimensions.

According to different processes, PM (Powder Metallurgy) can be divided into laminated sintering, spray deposition. Laminated sintering filled in a layer by layer according to raw material powder or a thin film of different components uniformly mixed in different mixing ratios so that the components are distributed in gradient and sintered. This method has been successfully used by researchers in China for preparing SiC / C, ZrO2 / NiCeSi3N4 / SUS and ZrO2 / SUS multi-functional gradient materials.

Tungsten copper specific structure is also called as fixed structure, which is beneficial for improving tungsten copper performance and design the special component according to the condition. The current use of more hollow type tungsten copper electrical contacts, has low ablation and long service life.

Working in the microwave band (frequency 300 ~ 300000 MHz) of the device, known as microwave components. Microwave devices can be divided into microwave oscillators (microwave sources), power amplifiers, mixers, detectors, microwave antennas, microwave transmission lines according to their functions. Tungsten copper heat sink used for microwave component plays an important role in mechanical support and heat conductivity, which is one of the important parts of microwave system.

The microwave components can be divided into microwave electric vacuum devices, microwave semiconductor devices, microwave integrated circuits (solid state devices) and microwave power modules according to their working principle, materials and processes. Microwave electric vacuum devices include klystron, traveling wave tube, magnetron, back wave tube, gyrotron, virtual cathode oscillator, the use of electronic movement in the vacuum and interaction with the external circuit oscillation, amplification, mixing, etc. Microwave semiconductor devices including microwave transistors and microwave diodes, with a small size, light weight, low power consumption, etc., but in high-frequency, high-power case, can not completely replace the electrical vacuum devices.

CPU will produce a lot of heat when it is working, if not timely disseminate the heat out, it is easy to lead to poor computer operation, or even burn the CPU. Tungsten copper heat sink used for CPU can cool it down and keep working stability.

According to the way of cooling, tungsten copper heat sink for CPU can be divided into three types of air cooling, heat pipe and water cooling.
Air cooling: The most common type of heat sink, including a cooling fan and a heat sink. The principle is the heat generated by the CPU to the heat sink, and then through the fan to take away;
Heat pipe: It is a heat transfer element with extremely high thermal conductivity, which transfers heat by evaporation and condensation of the liquid in a fully enclosed vacuum tube. Most of these fans for the "air-cooled + heat pipe", both air-cooled and heat pipe advantages, with high heat dissipation;
Water cooling: The liquid forced by pump and take away the heat of radiator, compared with air cooling, it is more stable and less dependence to the environment.

In terms of heat sink materials, each one has different thermal conductivity. According to the thermal conductivity of high to low is silver, copper, aluminum, and steel. However, the silver for the heat sink will be too expensive, the best solution for the use of copper. Although the aluminum is much cheaper, obviously is not as good thermal conductivity of copper and its alloys (only about 50% of copper). Commonly used heat sink material is copper alloy and aluminum alloy, both of them have advantages and disadvantages. Copper has better performance in thermal conductivity, but it has high cost, large in weight (Many copper heat sink have exceeded the CPU's weight limit), but easy to oxidize. And aluminum is not sufficient in hardness and not good as copper in thermal conductivity. Some radiators to take advantage of each other, in the aluminum radiator base embedded in a tungsten copper plate.
