What is a machined part?

Machined parts can be made of any material and cut to a variety of shapes and sizes. Machining is the process by which a metal “aluminum, brass, steel”, plastic, or wooden piece is created from a raw block of material.

Machining is an ancient technique that involves the use of cutting tools to remove excess material from a metal or other substance.

A machined part is any piece of metal that has been changed by the use of milling or drilling. The machining process removes material from the surface of the metal to form the desired shape. These pieces are often used in machinery and other products.

Different Types of Machined Parts in Manufacturing Processes

Different Types of Machined Parts in Manufacturing Processes

Machining metals is a process to create three-dimensional objects from a metal block or billet by removing material to form the final shape. There are many types of machined parts in manufacturing processes such as:

The propelling systems in rockets and jet engines;

The rotating shafts, crankcases and camshafts in automobiles;

The crankshaft and camshaft in diesel engines;

The turret head and gun barrel for machine guns and cannons;

Most machine tools (e.g., lathes, mills, drills);

Engine blocks, cylinder heads, crankshafts, connecting rods for vehicles.

Regardless of the manufacturing process used to create the end-use part, CNC machining is widely used by designers as a means of creating early and late-stage prototypes with short turnarounds times. CNC prototyping allow designers to rapidly iterate ideas without tooling costs or waiting times. It is one of the best ways to create concept model and function prototype to verify the design. Compared with other rapid prototyping methods, rapid CNC machining allows us to get tight tolerance prototypes in real materials fast.

CNC Prototyping is the preferred option to bring new design life among the other rapid prototyping methods, unless the products are designed for 3D printing or other methods only.

molding making

CNC machining and EDM are the main methods to fabricate metal tooling for injection molding, high pressure die casting, blow molding, roller molding, stamping, blending and so on.

High speed CNC machines allow us to make high precision copper patterns, mold cavities, mold base, lifter and other mold components in very short term. Moreover, with 5 axis milling machines, we can mill the deep pocket features in hours which take days to make by EDM in the past. That’s how we can speed up the mold making process significantly. Check out how rapid tooling works.

Automotive

In the automotive industry, CNC machining is the most popular way to create concept cars as well as the function testing components, such as lighting, engine, transmission & steering system. It is also widely used to produce high volume automotive parts and post-machining the die casting parts, investment casting parts.

It is especially useful for custom automotive parts, which may be required for repairs or for limited-edition luxury vehicles, since it is too costly to make few parts by molding process.

aero space

CNC machining has for several years been an integral part of aerospace manufacturing. That’s partly down to the extremely high precision of CNC machines, making the process suitable for safety-critical parts that will be used on aircraft.

Machinable aerospace parts include prototype engine components, fuel panels, landing gear components and engine mounts.

medical

The machinability of many grades of titanium and stainless steel makes CNC machining a widely used process in healthcare, with the process regularly used to create implants, medical devices and surgical tools such as scalpels.

Tight tolerances and fast turnarounds are especially important for items such as titanium hip implants, which should be tailored to a patient’s anatomy.

consumer products

Though injection molding dominates the production of simple plastic parts, many off-the-shelf goods are created with CNC machining. Household goods and appliances often contain machined parts, while items like enclosures and fixtures are also suitable for the process. Goods like sporting equipment may also be CNC machined. The CNC machining of metal and plastic components plays a big role in the electronics industry. Items such as laptop casings, connectors and sockets can all be reliably made with a CNC machine.

What is a Metal Machined Part and Why Should You Consider it?

What is a Metal Machined Part and Why Should You Consider it?

metal machined parts are usually manufactured from basic metals, such as steel and aluminum. They are commonly used in industries such as automotive, aerospace and defense.

Machine metal and machine steel refer to any metal that has been cold formed through a cold working process. These processes typically involve rolling the metal into sheets before it is punched into the desired shape or cut with a saw or laser.

Metal machined parts are created by cutting metal sheets with specialized machines, so they are often used for complex shapes that require great precision and accuracy.

-Benefits of Using Machine Metals for Your Machined Products

The benefits of using machine metals for your product can be extensive. It can both lower manufacturing costs and increase the durability of a material.

Machine metals are a type of metal that is manufactured by a CNC Machine, rather than through traditional forging methods. This means that it is much easier to produce. It is also much more durable as it has been subjected to less wear and tear from being hammered out traditionally by hand.

-Types of Machine Metals & Which One is the Best For You?

There are three main types of metals used in the manufacturing process: Aluminum, brass, and steel. Each metal has its own properties that make them suitable for different applications.

01- aluminum machined parts:

 

Aluminum machined part is the lightest metal available with good strength-to-weight ratios. It is less costly than steel and easier to machine than brass or copper. However, aluminum is not as corrosion resistant or as strong as steel or copper.

Aluminum is the most commonly used metal making it great for any application where weight needs to be reduced without sacrificing strength. While there are other metals that may offer certain advantages over aluminum, it has an advantage in terms of low cost of production and ease of machining which makes it a very versatile material for many applications.

02- brass machined parts:

 

Machined brass parts are a set of plastic injection molds that are produced by injecting molten resin into a cavity in the mold.

Machined brass parts are usually used to produce plastic injection molds with repetitive designs. They can also be used in the production of expensive products such as medical equipment, medical appliances and electrical components.

03- stainless steel machined parts:

 

Stainless steel machined parts are metal components that have been manufactured through various levels of precision machining. They can be used for a wide variety of applications, from furniture to appliances. In this article, we will explore the properties and use cases of these parts in more detail.

In addition to being durable, stainless steel parts also have a useful resistance to rust due to the chromium content in the alloy mix. This makes them a popular material for any type of application where water might come into contact with the product over time – such as kitchens and bathrooms.

04- Titanium precision machined parts:

 

Titanium is a metal with a low density and high strength. It is one of the most corrosion-resistant materials known, and has a melting point that is relatively high.

Titanium machined parts are commonly used in aerospace, medical, food and beverage, consumer goods, and design sectors. Titanium machined parts are also used in defense industries such as missiles and satellites.

An example of a Titanium machined part is the nozzle on the liquid oxygen tank of the space shuttle.
