Because the main engine production line pursues high efficiency and production takt balance, and on limited equipment, for high efficiency and takt balance, the tool is often required to 

use the largest possible processing parameters. In the process of machining, the tool life is often sacrificed to meet the takt requirements, but at the same time, the minimum tool life must 

be guaranteed. In order to keep auxiliary times as low as possible, compound tools and special tools are also used extensively. This reflects the characteristics of high efficiency.

Automotive production requires extremely high reproducibility and repeatability. It is required that the quality of long-term supply tools should be highly consistent, such as achieving the 

same tool life and dimensional deviation. The consistency of key dimensions in the production of automobile enterprises is very high, which also requires different batches of tools to have 

a high degree of identity.

The processing requirements of the automotive industry are relatively high (up to um level), and quality is the first indicator for tool purchases by automotive companies. Moreover, 

high-quality cutting tools can bring about a significant reduction in production costs, and high-quality cutting tools can also reduce the cutting tool cost of the powertrain.

Specialization can achieve high efficiency, improve processing efficiency, and increase productivity. Specialization can also improve processing quality, achieve high stability, maintain high 

processing stability, and achieve high reliability. Specialization can promote low cost, consistent with "lean manufacturing" principles.
