How CNC Machining is used in Automotive Production

For many of the key components, CNC machining is the go-to option for designing prototypes and finishing production, used for jobs like boring and drilling with automation and computer control.

There have been numerous changes that have occurred in the automotive industry with regard to the manufacturing processes used. In the beginning, most of the production of cars when they started to be made on mass, was completed by hand. In the time since, robots have become a more common feature, more quickly handling all the tasks like assembly and welding than human workers.

CNC machining involves the translation of digital files into sequence computer instructions. The instructions are then directed to a motor-powered tool like a mill, lathe or drill. Through cutting and other techniques, the tool produces a finished component or part from a block of the required material.

Compared to conventional machine work, CNC machining is far more accurate and precise.

Car Parts Made Using CNC Machining

Lighting

Of all CNC machining applications used in the modern automotive sector, aluminum machining is perhaps the most important. Besides aluminum, Poly and acrylic glass can also be cut using CNC machining. Machine work with Poly allows car manufacturers to create lighting for cars and other vehicles, both on the inside and outside. The process is much quicker when CNC machining is involved, even though the sections of acrylic need to be polished and ground down. You can find more details on the process at Rapid Direct.

Engines

There are several important components for car engines that can be produced using CNC machining. A cylinder block, for example, can be worked from an aluminum block using CN machine processes.

It does take a lot of time to program CNC machines and this involves a great deal of specialized skill, once you have set up the machines it will be able to carry out the instructions laid out for it without too much input. This means that many engine blocks can be worked on and produced in an efficient and time-saving sequence without requiring too much more labor.

The main parts of a car engine that can be created using CNC machine processes are:

  • The components that hold the engine cylinders above the engine cylinder block
  • The cylinder heads

Other Car Parts and Components

As well as lighting and engine-related components, there are a few other parts and components that CNC machine processes can be used to create, including:

  • The housing for carburetor
  • Valve retainers
  • Components and parts related to the suspension system
  • Bushings
  • Exhaust parts
  • Components and parts of the fluid system

Additionally, the CNC machine process can be utilized for the customization of cars and other vehicles, along with the components specific to those customizations. This is down to the fact that computer-aided design enables designers and manufacturers to quickly alter the designs of parts to fit the customization plans.
