CNC machining technology has a wide range of applications in the field of automotive manufacturing and is capable of machining a wide range of automotive parts.

The following are the main categories of automotive parts that can be machined by CNC and their characteristics:

1.Engine components
Crankshaft: Crankshaft is an important part of the engine, its shape is complex and requires high precision, CNC machining technology can ensure the high precision machining of the crankshaft, so as to improve the performance and reliability of the engine.
Camshaft: The camshaft controls the opening and closing of the engine valves, and the accuracy of its surface profile has a direct impact on engine performance. CNC machining ensures accurate machining of the camshaft.
Cylinder head cover & cylinder block: These components have extremely high requirements for sealing and strength, and CNC machining enables precise machining of complex internal cavities and bores to ensure the quality of cylinder heads and blocks.
Connecting rod: Connecting rods connect the crankshaft to the piston and are subjected to high alternating loads. CNC machining ensures the precise size and shape of the connecting rods and improves their service life.

2.Transmission System
Gear rack: Gear is a key component in the transmission system, its tooth shape accuracy directly affects the transmission efficiency and noise level, CNC machining technology can achieve the precise processing of gear tooth shape.
Bearing: Bearings support rotating parts and bear loads, and their precision and surface quality have a significant impact on bearing life and transmission efficiency. CNC machining ensures high precision machining of bearings.
Drive shaft: Drive shafts transmit power and torque, and CNC machining enables precise machining of drive shaft surfaces and critical mating surfaces.

3.Chassis components
Suspension components: Such as steering knuckles, suspension arms, etc., the structure of these components is complex and requires high precision, CNC machining can ensure the accurate processing of suspension system components, thereby improving the stability and safety of the vehicle.
Brake system components: Such as brake discs, brake pads, etc. These components have strict requirements for flatness and dimensional accuracy, and CNC machining can ensure high-precision machining of brake system components.

4.Body components
Structural body parts: Such as the body frame, door hinges, etc., these parts need to bear the weight and vibration of the body, the strength of the material and precision requirements, CNC machining can ensure that the body structure parts of the precise processing.
Exterior body parts: Such as doors, windows, roofs, etc., these parts have high requirements for surface quality and appearance, CNC machining technology can achieve precise machining of complex curved surfaces and structures, and improve the aesthetics and airtightness of the body.

5.Electronic components
CNC machining technology is also widely used in automotive electronic parts processing. For example, in the manufacture of automotive electronic control components, CNC machining centres can process sensors, actuators, controllers and other parts, improving production efficiency and product quality.

6.Other components
Fasteners and connectors: CNC machining technology is also able to process a variety of automotive fasteners and connectors, the quality and accuracy of these parts have an important impact on the performance and service life of the car.
In automotive welding, for example, CNC machining centres can process complex welded structures and welded joints, improving welding efficiency and product quality.
