Molybdenum Machining Components

Molybdenum is used in a wide range of industries to manufacture machining parts. It is one of the most important refractory metals which has the characteristics of retaining tensile strength at above 1000 degrees centigrade. Additionally, it has a low co-efficiency of heat expansion and is able to conduct electricity very well. Due to these properties, the metal is used to make assemblies and the components used in lighting, semiconductor, and electrical industries.
Many industrial productions of alloys include molybdenum as one of the most significant constituents in order to increase electrical conductivity, strength, resistance to corrosion and wear, and hardness. This metal can be found in many different products including engine parts, lubricant additives, missiles, electric-heater-filaments, saw blades, coatings in boilers, drills, and among others.
It is shiny and silvery and although it is regarded as a toxic element, it is known as an essential micro-nutrient for the life of both animals and plants. The metal exists in a number of isotopes such as Mo-98 (24.1%), Mo-100 (9.6%), Mo-95 (15.9%), Mo-97 (9.6%), Mo-94 (9.2%), Mo-92 (14.8%), and Mo-96 (16.7%). This article looks at the machining components of molybdenum.
Molybdenum Machining Components Overview
Molybdenum can be machined to produce very simple or complex shapes, and small intricate metal parts. All the processes used in machining can be used to machine this kind of metal and no special procedure or equipment is required to ensure that the shapes are produced with the correct dimensions. The most common operations used to machine molybdenum components include sawing and shearing, milling and shaping, turning, and drilling, threading, and reaming.
Tools such as steel are used for roughing cuts on surfaces that are uneven or for making small quantities of the metal. The steel is usually of high speed. In some situations, sintered carbide with grade C2 is used. But the choice of the tool to use depends largely on the quantity of production. Carbide grades are used mostly for cast-iron. When manufacturing machined parts with molybdenum, the work should be firmly chucked, rigid machines should be used, tools should be sharp and supported well, and should be powerful enough and free of backlash.
Lubricants are not necessary when machining metal parts. But in some circumstances, they can be used with molybdenum to increase the speed of cutting, improve tool life, remove fine particles that can destroy the cutting tools, and remove heat from the cutting machines.
Soluble oils can be used in some cutting operations such as band saws and hacksaws. However, they are not effective for tapping, drilling, turning, and reaming. This is where highly chlorinated and sulfur base oils are advisable for use in most cutting operations. But cutting oils that are sulfur base are not recommended for machining parts that are electrical. This is because they are deleterious and this property can have a bad effect on the final products.
Special methods of machining can be used when making molybdenum parts. These include grinding, honing, and buffing, and photo-etching and electro-polishing.
Final View
When manufacturing and assembling molybdenum components, a lot of processes take place. Commonly, computer-aided machining is used throughout the processes although manual operations are also common especially when adjusting minor things. Most of the items we use every day are made through machining. Making these items in a more cost-effective and quicker manner can improve efficiency, and ensures proper use of technology.
