Machined components are all such components that have been built using the machining process with the help of tools like milling, shaping, drilling, etc. The machining process is carried out on raw materials to give it different shapes and sizes. These components are widely used across all industrial products and became popular after the industrial revolution of the 18th century. Machined components vary in size ranging from a small watch gear to a gigantic turbine. Precision machined components are of great importance in almost every industry to deliver excellent performance. Machined components are greatly in use across diverse industries, from tiny metal fasteners to aircraft engine components, all such components are built using the machining process. Machined components are extremely popular in the manufacturing industry as turbines, automobiles, airplanes, ships, and railways all contain machine components.  

Classification of Machined Components

Machined parts are generally specifically fabricated components using cutting machines like mills, lathes, and routers. Though, all these machines work in different ways but their basic purpose is to cut sections away from a block of material using a sharp cutting tool. Generally made from ferrous and non-ferrous metal, machined components are classified as single machined components, joined machined components, and assembled machined components. Single machined components are made of a single material and have a homogenous shape. Some examples of single machined components are castings and sintered components. Joined machined components consist of two single components connected together by a process like welding, soldering, pressing, etc. or these components are made of several materials like compound castings, bearings, etc. Assembled machined components are made of several components joined together by binders like pins, screws, or spring fits.

Machined Components Considerations

Some of the aspects that need to be considered in machined components include the type of material, machining processes, and the type of machining used. While manufacturing machined components, a few other things also need to be considered such as the amount of scrap, and amount of electrical energy consumed. Some mechanical processes create a lot of waste in the form of solid, liquid, and airborne particulates, all these should be minimized. The designing of the components is another vital consideration, though the design cost is just 5% of the actual production cost of the machined components. Perhaps, perfectly designed machined components save as much as 50% of the production cost and are also effective in:

Different Materials used to make Machined Components

Machined components are made with a wide gamut of raw materials, as per the needs of diverse industries. Some of the common materials that are used to make machined components are:

Commonly Used Machined Components

High precision machined components are used across a wide range of harsh and extreme environments like nuclear, oil, defense, and aerospace industries. These components are usually machined from materials to resist heat, pressure, steam, and corrosion. Some of the commonly available machined components are:

Summary: Machined components have become an integral part of our daily life, as these components play a crucial role in all industrial setups. Right from medical, electrical, electronics, and automobile industries, machined components are used across diverse industries where end products are manufactured by joining together several machined parts. Manufacturing machined components require dedication, expertise, as well as advanced technology.
