What Is EDM Molybdenum Wire?

EDM is Wire Electrical Discharge Machining, while EDM molybdenum wire is a thin wire used to cut and shape electrically conductive materials with a high degree of precision. This method is particularly effective for materials that are difficult to machine using traditional mechanical methods. 

Here's how molybdenum wire cutting works:

Setup: In molybdenum wire cutting, a thin molybdenum wire, typically around 0.1 to 0.3 mm in diameter, is used as an electrode. The workpiece, which is usually made of a conductive material like metal, is submerged in a dielectric fluid, often deionized water.

Electrical Discharge: An electrical potential is applied between the molybdenum wire and the workpiece, creating a spark discharge. This spark generates intense heat, causing the material in its path to vaporize and erode.

Material Removal: The spark erodes the workpiece, creating a narrow cut or kerf. The material that is vaporized is carried away by the dielectric fluid.

Wire Feeding: The molybdenum wire is continuously fed through the workpiece. As the wire advances and the workpiece is eroded, the desired shape or cutout is achieved. The process is computer-controlled, ensuring high precision.

Cooling and Debris Removal: The dielectric fluid serves several purposes. It acts as a coolant to prevent the wire from overheating. It also flushes away the eroded material and debris from the machining area.

High Precision: Molybdenum wire cutting is known for its high precision. It can be used to create intricate and complex shapes with tight tolerances.

Minimal Heat-Affected Zone: Unlike traditional cutting methods, molybdenum wire cutting generates very little heat in the workpiece. This results in a minimal heat-affected zone, making it suitable for materials that are sensitive to heat.

EDM molybdenum wire is widely used in industries where precision machining of hard or exotic materials is required. It is valuable in the manufacturing of aerospace components, medical devices, injection molds, and other applications where intricate shapes, fine details, and minimal thermal distortion are critical. Additionally, it is an efficient method for cutting materials that are extremely hard or materials that cannot be machined by conventional methods.

The Working Principles of Molybdenum Wire Cutting

Wire Electrical Discharge Machining (Wire EDM) is a non-conventional machining process that employs molybdenum wire as an electrode to cut and shape conductive materials. The working principles of molybdenum wire cutting, which is a subtype of EDM, are as follows:

1.Electrical Discharge: At the core of Wire EDM is the principle of electrical discharge. The process begins with a molybdenum wire, which acts as the cutting tool, and a workpiece made of a conductive material (typically metal). The molybdenum wire is threaded through the workpiece.

2.Dielectric Fluid: Both the molybdenum wire and the workpiece are submerged in a dielectric fluid, such as deionized water, which serves multiple purposes: It acts as an electrical insulator, preventing premature discharges between the wire and the workpiece; The dielectric fluid is continuously circulated to flush away debris and molten material from the cutting area; It helps to cool the workpiece and the molybdenum wire.

3.Electrical Discharge Generation: A high-frequency power supply is used to apply electrical voltage between the molybdenum wire and the workpiece. When the voltage is increased to a critical level, electrical discharges occur between the wire and the workpiece. These discharges are sparks or arcs that have very high energy.

4.Melting and Erosion: The intense heat generated by the electrical discharges causes localized melting and vaporization of the workpiece material at the point of contact. The high-energy discharges also create a small crater or indentation in the workpiece.

5.Removal of Debris: The dielectric fluid, which surrounds the machining area, helps remove the molten material, debris, and particles created by the electrical discharges. The flushing action of the dielectric fluid keeps the cutting area clean.

6.Controlled Motion: To cut the workpiece into the desired shape, the molybdenum wire is continuously fed through the workpiece. The wire is driven by a CNC (Computer Numerical Control) system, which precisely controls its speed and direction. The controlled movement of the wire ensures that the desired shape is cut.

7.High Precision: The process is highly accurate and capable of creating intricate shapes and fine details. The precision is achieved by controlling the electrical discharges and the movement of the wire.

8.Minimal Heat-Affected Zone: Wire EDM generates minimal heat in the workpiece, leading to a small heat-affected zone (HAZ). This is particularly advantageous when cutting materials that are sensitive to heat or when maintaining tight tolerances is essential.

Molybdenum wire cutting is used in various industries, such as aerospace, medical device manufacturing, tool and die making, and more, where precision, intricate shapes, and minimal heat-affected zones are critical. It is a non-contact and non-traditional machining process known for its high accuracy and the ability to cut even the hardest materials.

Molybdenum Crucible Price in Early November 2023

The latest price of Φ32xΦ28x150mm molybdenum crucible is USD135.00/PC, EXW XIAMEN, CHINA in early November 2023. 

Corrosion resistance, creep resistance and high temperature performance make molybdenum made crucibles very suitable for high temperature crystal growth processes. When sapphire is easy to extract, higher sapphire yield and quality can be achieved. The molybdenum-based crucible has heat resistance and a smooth surface, making it durable and cost-effective.

The surface roughness of the molybdenum crucible needs to be higher than 1.6 µm. When the surface of the crucible is rough, the sapphire is not easy to take out and it is easy to damage the crystal. In addition, the crucible will be damaged in the process. Chinatungsten Online's ultra-smooth crucible eliminates these problems. Sapphire manufacturers can benefit from this product because it eliminates complex and expensive processes. In addition, the smooth surface is resistant to corrosion caused by aggressively molten sapphire. This function can extend the service life of reusable crucibles.

Why Can Molybdenum Wire Cut Metal?

Molybdenum wire is used in a process known as Wire Electrical Discharge Machining (Wire EDM or WEDM) to cut or shape metal and other conductive materials. It can cut metal for several reasons:

Electrical Discharge Machining (EDM) Principle: Wire EDM is a non-traditional machining process that uses a thin wire electrode to cut through the workpiece material using electrical discharges. It relies on the phenomenon of electrical sparks (discharges) between the wire and the workpiece, which can remove material through a controlled spark erosion process.

Conductivity: Molybdenum is a highly conductive material. It allows electrical currents to pass through it easily, making it suitable for use as an electrode in EDM. When an electric current is applied to the moly wire, it generates localized electrical discharges that melt and vaporize the workpiece material.

High Melting Point: Molybdenum has a very high melting point (approximately 2,623 degrees Celsius or 4,753 degrees Fahrenheit). This property allows moly wire to withstand the extreme heat generated during EDM without melting or deforming.

Precision and Accuracy: Wire EDM is known for its high precision and accuracy in cutting intricate shapes and contours in various metals. The thin moly wire can create very fine cuts and tight tolerances, making it suitable for applications in industries such as aerospace, medical devices, and toolmaking.

Non-contact Process: Unlike traditional machining methods that involve physical cutting tools, Wire EDM is a non-contact process. The moly wire does not touch the workpiece, reducing wear and eliminating the risk of tool breakage.

Heat-Affected Zone (HAZ): Wire EDM generates a minimal heat-affected zone in the workpiece, which means there is little to no distortion or metallurgical changes in the material being cut. This is beneficial for cutting materials that are sensitive to heat, like hardened tool steel.

Overall, molybdenum wire is a crucial component in Wire EDM, a highly precise and effective method for cutting and shaping metal and other conductive materials without introducing mechanical stresses. This makes it a preferred choice in industries where precision and quality are of utmost importance.
