Manufacturers continue to expand the business areas of hybrid and pure electric vehicle products. Kennametal utilizes the design flexibility of the additive manufacturing process to meet the growing needs of customers for lightweight tool solutions in the field of electric vehicle parts processing. Innovative 3D printed motor hole finishing tools combined with carbon fiber body and mature technology RIQ blades can perform well in deep hole machining applications of motor housings, greatly improving productivity and reliability.
What was the original intention of developing this new cutting tool product?
Kenner launched this tool to meet customer application needs. As global automakers transition to the hybrid and pure electric vehicle business areas, new tool solutions are needed to meet the unique challenges of electric vehicle parts processing, such as special tool products designed for machining motor housings. In this application field, in addition to the short processing time and reliable chip removal performance, the tool is usually required to have simple operation performance, such as error-free cutting edge setting process. The tool must also be designed to be lightweight to meet the requirements of the tool change system. In the manufacturing process of electric vehicles, manufacturers need to switch tools on different production lines, and Kennametal’s motor hole finishing tools weigh about half of the traditional manufacturing type tools, so automakers can use their existing high-speed machining centers Use this tool on the site. In the field of motor housing machining, we face the challenges brought by deep holes and a variety of large-diameter machining. Kennametal’s tools can effectively meet these challenges.
How to help customers increase productivity and processing efficiency?
The motor hole finishing tool can process three diameters at the same time in one operation, and ensure that the machined surface has excellent parallelism and concentricity, while also significantly shortening the processing cycle.Lightweight3D printingCombined tools can achieve faster tool change operations, even on machines with lower power and torque, they also have excellent performance.
No other additional conditions are required to meet the requirements of surface dimensions and part tolerances. The wing-shaped arm design ensures smooth chip removal performance, and the stacked internal cooling design can ensure that the coolant is accurately delivered to the cutting edge and the guide bar, while also ensuring a strong and efficient coolant supply.
In addition, Kennametal’s RIQ tool holder can easily adjust the machining diameter and can easily set new cutting inserts. While improving processing reliability, it can also save customers valuable tool adjustment time.
Why use 3D printing and carbon fiber reinforced composite materials
Through 3D printing, materials can be stacked according to our needs-no need to start from a cube or cylinder blank, so we can make complex tools more lightweight and ensure better performance in the processing process.By using the design flexibility of finite element simulation and 3D printing, we have reduced the weight of the motor hole finishing tool by about 50% (compared to the traditional tool), and at the same time can meet the high
standard
Dimensional accuracy, form and position tolerance and surface quality requirements. 3D printing allows us to achieve complex spatial geometries, thereby improving the performance of the tool, which is difficult or impossible to achieve economically with traditional manufacturing techniques. This includes the unique cooling channel of the tool and the wing-shaped connection design between the tool body and the cutting edge, which helps to improve chip evacuation performance, avoid the formation of built-up edge, and protect the surface of the workpiece.
The use of new materials such as carbon fiber reinforced composite materials (CFRP) can ensure excellent rigidity and strength performance, as well as the best damping performance, while also significantly reducing weight, which also helps to improve the overall performance of the tool.
What are the unique features of this tool?
Motor hole finishing tools provide a combined tool solution, which applies Kennametal’s expertise in additive manufacturing and traditional manufacturing. This tool is used in conjunction with our proven RIQ inserts, which have demonstrated excellent finishing performance in many customer applications. This tool can be used with all commonly used tool holder interface forms. In applications with higher requirements for rigidity, speed and accuracy, Kennametal’s unique KM4X tool holder is recommended.
The EV motor hole finishing knife uses the combination of additive manufacturing and traditional manufacturing processes to provide unparalleled productivity in the field of motor processing.
