In the dynamic landscape of new energy vehicles, the direct - drive gear sleeve stands as one of the pivotal components. As the linchpin connecting the motor and the drive shaft, it shoulders the critical responsibility of power and torque transmission. Its ability to curtail transmission losses and enhance transmission efficiency is not only a testament to its significance but also a determinant of the vehicle's overall performance. The machining quality of the direct - drive gear sleeve, in fact, wields a profound influence over the power transmission efficiency, performance, and long - term reliability of new energy vehicles.

However, the traditional machining procedures for direct - drive gear sleeves are fraught with formidable challenges. Quenched and tempered steel, a prevalent material for these gear sleeves, poses a significant hurdle during the cutting process. Owing to its high hardness, the material generates intense heat, leading to rapid tool wear. Conventional tools simply fall short of meeting the demanding processing requirements. In the finishing stage, the grinding process, while essential for ensuring precision and surface quality, escalates the machining cost substantially. Moreover, the intricate and convoluted traditional process chain hampers any attempts to boost machining efficiency.

This is where LINKUT, a leading name among PCBN Tools Manufacturers, steps in with innovative solutions. Leveraging its expertise in PCBN tool production, LINKUT has successfully addressed these challenges. By deploying LINKUT PCBN inserts to directly hard - turn quenched and tempered steel gear sleeves, remarkable outcomes have been achieved. This application within the realm of PCBN Tools Application Fields showcases the versatility of these tools in the demanding sector of new energy vehicle part machining.

The exceptional PCBN Tools Cutting Performance is vividly demonstrated in this process. LINKUT's PCBN inserts have enabled the elimination of the traditional grinding process, streamlining the machining technology. This not only enhances machining efficiency but also cuts down on costs significantly, translating into tangible economic benefits for customers.

In a specific case, the workpiece was a new energy direct - drive gear sleeve crafted from quenched steel with a hardness of HRC58 - 62, and the machining focus was on the end face. Given the intermittent machining nature of the end - face keyway, LINKUT employed an intermittent finishing method coupled with a wet - cutting cooling approach to guarantee machining stability and quality. Stringent machining accuracy requirements were in place, with the roughness target set at Ra0.8 and the machining allowance controlled at 0.1.

For the unique working conditions of finish - turning the end face of the quenched and tempered steel gear sleeve, LINKUT capitalized on its technical prowess and introduced a customized cutting edge. This innovative design effectively extended the tool life by an impressive 53% compared to previous methods. The outstanding performance of LINKUT tools allowed them to replace the original imported tools, meeting customers' strict quality demands while reducing the unit machining cost significantly, thereby empowering customers to gain a competitive edge in the market.

As a dedicated PCBN Tools Manufacturer, LINKUT remains committed to technological innovation, constantly striving to provide customers with superior, efficient, and cost - effective machining solutions. In the future, LINKUT will continue to explore and innovate in the machining domain of new energy vehicle parts, further expanding the horizons of PCBN Tools Application Fields and contributing to the growth of the new energy vehicle industry.
