CNC Machined Car Parts

1. Engines

CNC machining can be used to create a few key components of a car’s combustion engine. For instance, a large aluminium block can be machined into a cylinder block. This is the metal structure that contains an engine’s cylinders where moving pistons travel up and down.

Though programming the CNC machine is a time-consuming process that requires a high level of skill, once prepared the machine can carry out its instructions without any assistance. Therefore, numerous engine blocks can be machined in sequence without a significant increase in labour.

Engine parts also generally produced using CNC machining techniques include:

• Cylinder heads
• Parts that enclose the cylinders above the cylinder block

1. Lighting

In the automotive industry, machining of aluminium is one of the most important applications of CNC machining. However, materials such as acrylic glass or Poly (methyl methacrylate) (PMMA) can be used to make other significant components.

Machining PMMA enables manufacturers to produce lighting for a vehicle, both its headlights and interior lighting. Even though these acrylic pieces need grinding and polishing after the CNC machining, the entire process is still quite fast. Therefore, allowing auto manufacturers to prototype new light fixtures for their cars quite quickly.

Commonly used as a shatter-resistant alternative to glass, PMMA can also be used for:

• Fish tanks
• Transparent shields
• Windows

1. Other parts

CNC machining is also used to produce a vast range of other car parts, such as:

• Fluid system components
• Exhaust parts
• Bushings
• Suspension components
• Valve retainers
• Carburettor housings

In addition, CNC machining is particularly useful for customising vehicles and their specific components, since CAD allows for the quick alteration of part designs.
