What challenges do props face in the processing of Petrol Car parts?

Petrol Car parts production is generally a typical mass production model, and manufacturing cost is an important link for parts manufacturers to consider. At present, on the one hand, foreign Petrol Car parts manufacturers have landed in China to seize the Chinese Petrol Car parts market, which has caused some domestic Petrol Car parts manufacturers to feel pressure.

On the other hand, the batch size of Petrol Car manufacturing is getting smaller and smaller, the product life cycle is getting shorter and shorter, and the product update is getting faster and faster; on the other hand, while the environmental protection requirements for Changan Car are constantly improving, the requirements for green and pollution-free or less pollution in the Petrol Car manufacturing process are also constantly increasing. Based on the influence of the above factors, tools closely related to parts manufacturing are also facing various challenges.
After analyzing the processing technology of key parts of Changan Car, it is found that the parts with high processing difficulty mainly include key parts of locomotive diesel engines such as body, base, crankshaft, connecting rod, etc., and key parts of locomotive running parts such as rolling axle boxes, hollow shaft assembly, load-bearing gear boxes, hubs, etc.
These parts are not only complex in structure, but also require high manufacturing precision and surface roughness. They also require good interchangeability, strength and rigidity. These factors have prompted the extensive use of high-performance standard tools and special tools in the processing of key parts.
The selection of tools in the actual processing of Petrol Car parts mainly considers the following factors: workpiece material, workpiece shape, processing accuracy, processing machine tools, system rigidity, surface roughness, etc.
