CNC turned parts play a crucial role in automotive manufacturing. The following are some common CNC turned parts used in automobiles:
Axis parts: such as transmission shafts, half shafts, camshafts, etc. These parts require high-precision dimensions and good surface quality to ensure the power transmission of the car and the normal operation of the engine.
The transmission shaft is responsible for transmitting power from the transmission to the drive wheels, and its accuracy directly affects the smoothness and power transmission efficiency of the vehicle.
The camshaft controls the opening and closing of valves, and its shape and accuracy have a significant impact on the performance and fuel economy of the engine.
Piston components: including piston pins, etc. The piston undergoes high-speed reciprocating motion within the engine, and the piston pin needs to withstand significant pressure and friction, thus requiring high quality and accuracy.
Various connectors, such as steering rod joints, suspension system connectors, etc. These parts affect the handling performance and driving safety of the car.
The key components of oil pumps and water pumps, such as pump shafts and impeller shafts, ensure their accuracy and performance to ensure their normal operation, thereby maintaining the lubrication and cooling system of the engine.
Sensor components: Some precision parts in sensors used to monitor the operation status of cars may also be machined by CNC machining.
The characteristics of CNC Turned Parts as follows:
High precision:
CNC technology ensures extremely high precision in the size and shape of CNC Turned Parts by precisely controlling the motion of the machine tool.
The reverse clearance of the feed transmission chain and the pitch error of the lead screw can be compensated by the CNC device, enabling the CNC machine tool to achieve high machining accuracy.
High efficiency:
The CNC machine tool has a high degree of automation and can continuously process CNC Turned Parts, significantly improving production efficiency.
The adjustment range of the main oil speed and feed rate of CNC machine tools is larger than that of ordinary machine tools, so the most favorable cutting amount can be selected for each process.
Especially for CNC machining centers that use automatic tool changing devices, multiple continuous processes can be achieved on a single machine tool, resulting in a more significant improvement in production efficiency.
Strong adaptability:
CNC machine tools only need to develop machining programs for workpieces to achieve CNC Turned Parts machining, which is particularly suitable for single piece, small batch, and trial production of new products.
No need to produce batches of fixtures and repeatedly adjust the machine tool, reducing production costs and time.
Wide processing range:
CNC machine tools can process various complex shaped parts, such as CNC Turned Parts with complex shapes and special requirements.
Through multi coordinate axis linkage, it is possible to complete the machining of many spatial curves and surfaces that are difficult or impossible to machine with ordinary machine tools.
Low labor intensity:
The work of CNC equipment is automatically and continuously completed according to the pre programmed processing program, greatly reducing manual operations and lowering the labor intensity of workers.
Good economic benefits:
Although CNC equipment is expensive, using CNC equipment can save many other costs, such as the manufacturing cost of fixtures and the time required to adjust the machine tool.
Meanwhile, due to stable processing accuracy, low scrap rate, and overall cost reduction, enterprises can achieve good economic benefits.
