CNC machining uses computer controls and automation to carry out various manufacturing tasks such as boring and drilling. By following a set of pre-programmed instructions, CNC machinery controls tools such as mills and lathes to create finished products.

Due to the speed and accuracy of production, CNC machining has become a very popular option for manufacturing various automotive parts and components. At KDML, we offer CNC machining solutions for the automotive industry.

CNC Machining Within the Automotive Industry

Automotive manufacturing processes have changed significantly. Originally assembled mostly by hand, the use of robots became commonplace as early as the 1960s to carry out welding and assembly in a much shorter period of time. Today, CNC machining is the favorable option for handling tasks like drilling and boring for both prototyping and the production of vehicle components.

Primarily because of its speed, CNC machining has transformed the automotive industry. The process relies on CAD models and computer instructions with little or no human intervention, making it possible to manufacture large volumes of complex auto parts with enhanced accuracy, precision, and repeatability. One example of how CNC machining is used in the automotive industry is the production of combustion engine parts. CNC machining can take an aluminum block and machine it into an engine block.

Applications for the Automotive Industry

Applications for CNC machining in the automotive industry include:


With a complex design, modern gearboxes are small and require tight tolerances. Any error can cause gear wear, misalignment, and failure. Traditional gear-making processes, like hobbing, are being replaced with precision CNC machining, as this process allows for the production of quality gears without the need for additional post operations.

Cylinder, Intake Manifold, Engine Block

Due to compatibility with a wide range of materials, CNC machining is heavily relied upon for machining the cylinder, intake manifold, and engine block. It is also used for rapid prototyping and the production of other components, like starter motors.

Custom Parts

To create custom parts that are no longer in production, OEMs depend on reverse engineering and CNC machining. The process involves the creation of 3D CAD models of obsolete parts, which are then interpreted by CNC machining equipment to produce the desired part or component.

Interior and Roof Panels

To make high-performance cars that are more lightweight, many manufacturers use plastics and polymers instead of steel for interior and roof panels. CNC machining can fabricate dashboard frames and other interior or roof panels with the necessary cutouts for the speedometer, gas gauge, lighting, and more.
